Vote up the zaniest gender-determining methods from history.

For thousands of years, men and women have wanted to control the sex of their babies. Just like there were weird ways to test for pregnancy, there were all kinds of ways to determine the gender of a baby during pregnancy. Kings like Henry VIII wanted sons to ensure their royal lineage, and merchants wanted to avoid too many daughters so they didn't go broke because of rising dowry costs. Not surprisingly, most of these crazy theories about determining gender were about having a boy. 

These methods for how to know the gender of the baby during pregnancy at home used a lot of common objects: bananas, parsley, and bread, for example. But some of the ways people tried to determine gender were pretty crazy, like eating rabbits' unmentionables or even chopping off a man’s right nad. 

All of these home remedies to know the gender of a baby required dedication, from rubbing a woman with goose grease to testing the winds before conception. Some even advised getting it on right before a woman’s period

    In 18th-Century France, Men Who Seriously Wanted A Boy Cut Off Their Left Nut

    Men who only sort of wanted a boy could drink cola, but the truly committed took even more drastic actions. According to an 18th-century French text, The Art of Boys, the best way to guarantee a male baby was to cut off the left testicle. The left side was clearly where girls came from, so once it was gone, a man was biologically incapable of having a girl. 

    Of course, this theory was completely wrong. The men who did self-castrate were probably very disappointed!

    Start Looking For A Hare To Pulverize If You Want A Boy

    The Trotula, a 12th-century medical text, had some interesting advice for women who want to conceive a male child. “Let her husband take the womb and the vagina of a hare and let him dry them, and let him mix the powder with wine and drink it.”

    But before you start stalking rabbits, keep reading. “Let the woman do the same thing with the testicles of a hare, and at the end of her period let her lie with her husband and then she will conceive a male.” This advice is clearly only for people who are really serious about having a son.

    The Ancient Egyptians Said To Find A Green-Skinned Woman

    Sex-selection theories are nothing new in human history. As early as 2000 BCE, people were writing down tips for controlling the sex of your baby. An Egyptian papyrus written 4,000 years ago said that women with a greenish cast would certainly have boys.

    Once you’ve found a green-skinned woman, she can perform a pregnancy test that will predict the sex of her baby. She should urinate on emmer and barley, and if the barley grows, she is pregnant with a boy.

    Watch Out For Parsley On Your Head, And Stock Up On Goose Grease

    One of the most revered medical authorities in history, the ancient Roman Galen, claimed that placing a black ribbon on a woman’s left foot would lead to the conception of a girl. He also warned about the power of parsley. If parsley is placed on a pregnant woman’s head without her knowledge, her baby’s sex will be determined by the first person with whom she speaks. Men who really want sons could hide out with parsley waiting for the right moment.

    Galen also suggests rubbing a woman’s body with goose grease for two days and then copulating the next day – this will certainly result in a boy.

    If You Don’t Want A Girl, Find A Man With Strong Swimmers

    According to 12th-century nun Hildegard of Bingen, the sex of a baby is determined by the strength of the man’s seed. “When a man has intercourse with a woman with an emission of strong semen... a male child is conceived, since it is ordained by God.” If, on the other hand, the semen is thin, “then a female child is born, due to the weakness of the semen.”

    Yes, Hildegard was a celibate nun – but she was also a saint known for her medical writings, so people probably paid attention to her warnings.

    The Ancient Romans Suggested Tying Up The Family Jewels

    Pliny the Elder reported in his Natural History that tying up one testicle can determine the sex of an animal’s offspring. The method was guaranteed with sheep, Pliny promised. “If a ligature is put on the right testicle [the ram] gets females and if on the left, males.” Others pointed out that the same held true for cattle

    Pliny was silent on whether the same technique applied to humans, but it’s pretty much guaranteed that some Roman tried.
