Making Babies: Is it Possible to Influence Gender?

Note: for the purposes of this article, the terms “gender” and “sex” are used interchangeably.

This week’s double parasha, Tazria-Metzora, begins with the laws of when “a woman conceives and gives birth to a male…” (Leviticus 12:2) The actual Hebrew wording here is ishah ki tazria, literally “when a woman gives seed”. Based on this, our Sages taught that if a woman “gives seed” first, the child will likely be male, whereas if a man “gives seed” first, the child will likely be female (Niddah 31a). How exactly is this to be understood?

The classic explanation is that if the woman climaxes first during intercourse, the child from that union is more likely to be male—and vice versa. Of course, this statement is not a guarantee, for there have surely been countless situations where this was not the case. Some say, therefore, it is only a segulah for having boys. A further issue with the statement is that, scientifically-speaking, while for the man the climax does coincide with “giving seed”, for a woman the emission of the ovum (egg) is not related to climax. A woman “gives seed” on a cyclical basis, roughly once per month. Having said that, there may be a scientific basis to our Sages statement after all.

In the 1960s, Dr. Landrum B. Shettles, one of the pioneers of in vitro fertilization technology, proposed a method for sex selection during conception. Physiologically, it is the male seed that determines the gender of the baby: sperm carrying a Y chromosome produce a male, while sperm carrying an X chromosome produce a female. (Eggs, meanwhile, always have an X chromosome.) The Y chromosome is significantly smaller than the X chromosome which would, together with other factors, make the “male” sperm lighter and faster than the “female” sperm. At the same time, male sperm are more fragile and less likely to survive the acidic conditions of the uterus.

Based on this, to conceive a male, it is best to wait a few days so that the egg has travelled further down the fallopian tubes, allowing the male sperm to reach it faster, and before dying out. To conceive a female, it is best not to wait at all, and try to conceive earlier, while the eggs are deeper in the fallopian tubes, where male sperm are unlikely to reach. Shettles recommended that, if a couple desires a boy, they should start trying at ovulation time while if the couple wants a girl, they should try two or three days before ovulation. Ovulation is usually around Day 14 of the cycle.

Factoring in halakhah, if we add the seven clean days following menstruation, it generally comes to around Day 12 of the cycle. All other factors aside, this may favour the conception of a girl. Waiting a couple of days, meanwhile, might favour the conception of a boy. It is important to note that cycles vary; for some women ovulation might be a day or two earlier, or later. This may explain why some families have all girls, or all boys, for it is likely that conception always takes place on mikveh night, ie. at the same point in the cycle every time. Having said that, the Shettles Method is thought to be only 75% effective, and some studies say it isn’t effective at all, for there appear to be no major physiological differences between Y- and X-carrying sperm.

Intriguingly, the Shettles Method also recommends, as our Sages did, that a woman should climax first if the couple seeks a male child. This is because a woman’s uterine environment is acidic, but the secretions are actually more alkaline (basic), which diminishes some of that acid and makes it more likely for the male sperm to survive the journey.

The most significant factors are probably not biological at all, but spiritual. At the end of the day, God will send whichever gender is meant to be born. Thus, our Sages state that whoever is expecting a child and prays for a particular gender, “it is a vain prayer” (Berakhot 60a). However, Rav Yosef raises an objection to this statement, since we see in the Torah how Leah, after six boys, prayed for her next child to be a girl, the result being Dinah. It appears that praying for the desired gender does work! The Talmud resolves the contradiction with a Baraita:

The first three days [after intercourse], one should pray that the seed not putrefy. From the third day until the fortieth, one should pray that it will be male. From the fortieth day until three months, one should pray that it will not be deformed. From the third month until the sixth, one should pray that it will not be stillborn. And from the sixth month until the ninth, one should pray that it will be delivered safely.

So, one is permitted to pray for the desired gender of the child until the fortieth day of pregnancy. This is an incredibly precise scientific statement from our Sages, as today we know that the sex organs begin to form in the fetus around Day 42. While the chromosomes may have already determined the gender right at conception, God could certainly make a switch before Day 40 (who would know?) but after that point, the sex organs have begun to form and there is no going back. The Sages were also accurate regarding the putrefaction of the male seed, for today we know that sperm survives in the uterus for around three days, and no more than five days.

For the strict materialist-rationalist, there is nothing that can be done to select gender—it is just a game of chance, depending on which sperm penetrates the egg first. For the most pious person, there is no need to do anything either, for God knows best and it all depends on Above. Truly, it makes no difference, for each child is precious, and a miracle in its own right. I believe this is the deeper message behind our Sages’ debate on what is the ideal number of children that a couple should strive to have (Yevamot 62a):

Rabbi Natan taught: Beit Shammai say two males and two females, and Beit Hillel say a male and a female… It was alternatively taught [in a different Baraita]: Rabbi Natan said that Beit Shammai say a male and a female, and Beit Hillel say either a male or a female. Rava said: what is the reason? …as it is written: “He did not create it to be void; He formed it to be inhabited…” (Isaiah 45:18)

We are first given the most stringent opinion, that of Beit Shammai as expected, that a couple should ideally have two boys and two girls. At the end, we are given the most lenient opinion of Beit Hillel, the school of thought that Judaism is practically based on, which is that even a single boy or girl is enough to fulfil the mitzvah of reproduction. The Scriptural proof is a verse in Isaiah where the prophet quotes God as stating how He created the world to be full of life. The Sages are making an equivalence between the entire world and the birth of even a single child, which is enough to fulfil the mitzvah of populating the entire world. Each child is a world of his or her own and, as Abarbanel (1437-1508) comments on that verse in Isaiah, brings the world one step closer to the Final Redemption.

Do Men Have More Mitzvot than Women?

This week’s parasha, Tazria, begins by describing the rituals that a mother must perform upon giving birth to a new child. If the child is male, the mother is considered “impure” for seven days following her delivery, and then spends an additional 33 days in purification. For a female child, the durations are doubled, with the mother “impure” for 14 days, and purifying for another 66 days. Why is the duration of purification for a female doubly longer than a male?

‘Garden of Eden’, by Thomas Cole

The apocryphal Book of Jubilees (3:8) suggests an interesting idea: Adam was made on the Sixth Day of Creation but, apparently, Eve wasn’t made until a whole week after. This is why a mother of a male child is impure for a week, but a mother of a female child for two weeks! Jubilees also holds that Adam was only brought into Eden forty days after being created, while Eve was brought in after eighty days. This is why a mother of a male child needs a total of forty days to purify, and a mother of a female child needs eighty days. Of course, Rabbinic tradition rejects the Book of Jubilees, and it is accepted that Adam and Eve were both created on the Sixth Day, and were in Eden from the beginning.

Commenting on this week’s parasha, the Zohar (III, 43b) states that it takes a soul 33 days to settle in the body. This is primarily referring to the new soul that enters a newborn baby, as it takes time for the ethereal soul to get used to its descent into a physical world. The Zohar doesn’t add too much more on this, but we might assume that, based on the words of the Torah, it takes a male soul 33 days to settle, and a female soul 66 days to settle. At the same time, the Zohar may be referring to the soul of the mother, too, as she is the one that spends 33 or 66 days in purification. As we’ve explained in the past, the severing of the mother’s direct connection to her child distresses her soul for 33 or 66 days following childbirth.

Whatever the case, the implication is that a female soul is somehow greater than a male soul. It has more spiritual power, taking longer to settle. The notion that female souls are greater is found throughout Jewish texts, especially mystical ones. Sefer HaBahir, one of the most ancient Kabbalistic texts, states that the female soul is the most beautiful of all, and an aspect of the Shekhinah, the Divine Presence (chs. 173-175). It explicitly makes clear that life on Earth would be impossible without the life-giving mother, who in this regard is much closer to God.

On that note, it has been said that God created the world sequentially from simple to complex, starting with the basic elements: light, air, water, earth; progressing to plants, then simple animals, then mammals, then man, and finally woman. The woman is the last of God’s creation, and therefore the most intricate and the most refined. It may be because of this that the Arizal taught that while male souls typically reincarnate to rectify themselves, female souls rarely if ever reincarnate at all (Sha’ar HaGilgulim, ch. 9).

It is important to mention here that we are speaking of female souls, not necessary to all women. The Arizal (as well as the Zohar cited above) speak of the possibility of female souls in male bodies, or male souls in female bodies. And it should also be mentioned that this does not necessarily affect the body’s sexuality. A “female” soul in a male body can still very much be a heterosexual male, and vice versa. (For more on this, see Rav Yitzchak Ginsburgh’s lecture here on the female soul of the forefather Isaac, as well as the prophets Samuel, Jonah, and Habakkuk.)

There are a number of consequences to the greater souls of females. For one, it gives them binah yeterah, an “extra understanding” sometimes referred to as “women’s intuition” (Niddah 45b). This is one reason why the women of the Exodus generation, for example, did not participate in the sin of the Golden Calf, nor the sin of the Spies. In fact, the Kli Yakar (Rabbi Shlomo Ephraim Luntschitz, 1550-1619, on Numbers 13:2) states that, had Moses sent female spies, there would have been no problem at all!

On the other hand, a more elevated soul and an extra depth of understanding means a greater sensitivity to the world, which makes women generally less prone to violence and drug abuse, but significantly more prone to depression and anxiety. The greater female soul has the amazing potential to bring life, yet simultaneously (to balance the equation) the potential for severe destruction, “more bitter than death”, to borrow from King Solomon in Kohelet 7:26. This is symbolically reflected in the menstrual cycle, where a lack of conception of life necessarily results in the shedding of blood, a “minor death” that is then rectified in the living waters of the mikveh.

Finally, a greater soul means that women require slightly less mitzvot than men. After all, the “mitzvot were given only in order that human beings might be purified by them… their purpose is to refine…” (Beresheet Rabbah 44:1) A more refined female soul does not need the same mitzvot that a male soul does. Unfortunately, this has sometimes been a point of contention in modern times. Yet, upon closer examination, we see that the differences in mitzvot between men and women are actually minimal and, contrary to the general belief, there is a perfect balance between those mitzvot done exclusively by men and those done exclusively by women.

“Time-Bound” Mitzvot?

The general rule is that, at least in principle, women are exempt from any mitzvah that can only be done at a particular time. This includes mitzvot like prayer, tefillin, and tzitzit. However, in practical terms we see that this “rule” isn’t really a thing, and there are many time-bound mitzvot that women are obligated in. For example,

A Mystical Look at Pregnancy and Abortion

This week’s parasha, Tazria, begins by stating that a woman who gives birth to a son is spiritually impure for seven days, and requires another 33 days of purification afterwards. If she gives birth to a female, the impurity lasts fourteen days, followed by 66 days of purification.

The Zohar (III, 43b) comments on this section by first reminding us that each soul has male and female halves, and when the soul enters this world, it splits and enters two different bodies, male and female. If the two soulmates merit it, they will find each other and reunite. We are then told that the female part of the soul is larger and more powerful, which is why a woman who gives birth to a female needs double the purification time.

The Zohar explains why the Torah prescribes these specific time periods: 7 and 33 days for boys; 14 and 66 days for girls. It states that at birth, the soul first enters the body and is in complete disarray. For the first seven days, the unsettled soul “roams the body to find its place”. On the eighth day, the soul is finally getting comfortable in its new home. This is one reason why circumcision is done on the eighth day, once the soul is no longer distressed. The soul then needs an additional 33 days to acclimatize to its new environment until it has completely settled into the body. For the greater female souls, the time periods are doubled.

Note how these time periods are referring to the soul of the newborn, yet it is the mother that is described as being “impure”. This is because the mother carried the child, and its soul was housed within her temporarily. (Perhaps this extra soul is responsible for the well-known “pregnancy glow”.) Once the baby is born, its soul leaves the mother’s shelter and is now independent in the baby’s body. (And that pregnancy glow is gone!) The sudden loss of spiritual energy is difficult on the mother as well, and she requires forty (or eighty) days to get back to herself.

A major question arises here: if the soul only enters the newborn at birth, why is abortion forbidden? Religious groups of various faiths have argued for centuries on when exactly the soul enters the body, and many have taken the stance that a fetus already carries a soul, making abortion indistinguishable from murder. What do Jewish texts say?

Abortion and Gestation in the Talmud

In one passage, the Talmud includes abortion under the category of murder. However, it also famously states that if the mother’s life is at risk—at any point in the pregnancy—the fetus must be removed, “limb by limb” if necessary. In such cases, the fetus is seen as a rodef, a “pursuer”, referring to the Torah law that if one is “pursuing” another to kill them, it is permitted to kill the pursuer first. The Talmud concludes that a fetus can be aborted at any point until its head has emerged. Once the head has emerged, the newborn is considered completely alive, and in cases of life-risk, it is no longer clear who the “pursuer” is. The Sages suggest that the soul fully enters the newborn only at birth, and it is only then that the newborn is a complete person.

Elsewhere in the Talmud (Niddah 8b), we are told that the fetus already resembles a person at the three-month mark. We now know that it is precisely around this point that the developing baby has the features of a human (and is no longer called an “embryo”, but a “fetus”). The Talmud adds (Berakhot 60a) that until this three-month mark, a person should pray every day that there shouldn’t be a miscarriage. After three months, a person should pray that the fetus will not be stillborn, and after six months, a person should pray that the mother has an easy delivery. We are told that one should pray for the baby’s desired gender only before the 40-day mark. This, too, shows incredible wisdom on the part of our Sages. Today we know scientifically that the sex organs begin their development around day 42. The ancient rabbis knew that after day 40, gender development is already in progress, and there is no point praying for something different.

In a related passage, we are told that until day 40, the fetus is insignificant and more lifeless than living (Yevamot 69b). Today we know that the neural tube which will make the brain forms around day 40, and this is when the first neurons start signalling. Scientifically speaking, there could be no talk of any kind of consciousness or brain activity before day 40.

Because of this, most rabbinic authorities are far more lenient when it comes to abortions before the 40th day of pregnancy. Rabbi Chaim Ozer Grodzinski (1863-1940), who was widely recognized as the greatest posek of his generation, even suggested that abortions before the 40th day are not Biblically prohibited (Achiezer, III, 65:14). Nevertheless, even before the 40th day there is a potential to produce a living human being, and life is valued above all else, which is why abortions are still forbidden except for cases of absolute necessity.

By the 20-week mark (midway through pregnancy), fetuses are seen rolling around, sucking their thumbs, and responding to the prodding of the ultrasound. There is no doubt that the fetus is alive and aware at this point, and any abortion other than a life risk is hardly distinguishable from murder.

Soul Infusion

The fact that the fetus is aware by the 20-week mark (if not sooner) suggests that it does indeed have some level of soul. Yet, earlier we saw sources seemingly propose that the soul does not enter until birth. How do we reconcile these apparent contradictions?

To answer this question it is important to keep in mind that the soul is not one uniform entity. Rather, the soul is composed of multiple layers, each made up of countless sparks. The lowest level of soul is called nefesh, the basic life essence. Above that is the ruach, “spirit”, an animating force that, among other things, gives a person their drives and inclinations. Then comes the neshamah, a higher level of consciousness and the part that gives one their unique traits and qualities. Further still is the chayah, the aura that emanates from the body, followed by the loftiest level, the yechidah, which may be described as a spiritual umbilical cord between each soul and its Creator.

The Arizal taught that ever-higher levels of soul are accessed gradually over the course of one’s life. At birth, a person has only a complete nefesh. As they grow, they are infused with ruach, which becomes fully accessible at bar or bat mitzvah age. At this point one starts to tap into their neshamah, which is wholly available only at age 20. (For this reason, the Torah considers an adult one who is over 20 years of age. Only those over 20 were counted in the census and allowed to join the military. Our Sages state that although one may be judged for their crimes before age 20 here on Earth, only those sins accrued after age 20 are judged in Heaven. Meanwhile, the Midrash notes that Adam and Eve were created as 20 year olds.) The Arizal taught that most people never end up accessing their entire neshamah, and only the most refined individuals ever unlock their chayah and yechidah.

Based on this model, we see that right from conception the developing embryo is steadily infused with nefesh, the basic life force. By day 40, there is enough nefesh for the embryo to be considered alive. In fact, it is said that this is why the gematria of אם, “mother”, is 41, since a woman becomes a mother on the 41st day of pregnancy.

Once its entire nefesh has been infused, the baby is ready to be born. At birth, it begins to receive its next soul level, the ruach. A careful look at the Zohar passage with which we started reveals that this is precisely what the Zohar meant, as it explicitly mentions the ruach entering at birth, requiring forty days to fully settle in. Therefore, a developing fetus does indeed have a soul, which is why abortion is so highly discouraged—reserved only for true medical cases—and why it has been compared to murder.

Solving a Scientific Mystery

The above also answers a mystery that has been perplexing biologists for decades: what is it that drives an embryo to grow? Why do the cells multiply, and how do they know to differentiate? Each cell is exactly the same, with the exact same set of DNA, yet one clump of cells knows to form the eyes while another knows to form the liver, and so on. Scientists have still not been able to figure out how the embryo “knows” what to do. (For that matter, we can’t figure out how any cell really “knows” what to do.)

The Kabbalists have an answer: it is the steady infusion of soul that drives a mass of undifferentiated cells to do what it needs to. It is the soul that gives the instructions for how the DNA is to be transcribed and translated in each cell, and how the cells are to interact with one another. As the soul grows, so too does the body. It is therefore not surprising that around the age when most people’s bodies stop growing, their souls tend to stop “growing” as well.

This should remind us that our education does not end with formal schooling, nor does maturing stop with the end of puberty. The process of growth and refinement, both physical and spiritual, must continue throughout life. This is the key to true self-fulfillment and happiness.
