Normal women normally ovulate one egg at a time. Ovulation stimulants increase the number of eggs a woman ovulates, so in theory, they increase the chances of conceiving multiple children to some extent. Ovulation stimulants may theoretically increase the chances of conceiving twins, but at the same time, they can significantly increase the risk of pregnancy and even put the fetus at risk of malformation! “Ovulation stimulants are prescription drugs, originally developed for women who are unable to ovulate naturally, and it is very dangerous to take them without medical supervision, and they have side effects that cannot be ignored. The ovaries are born with a life span and the number of follicles has long been determined and will not be regenerated by any factor. During a woman’s lifetime, there are usually only 400-500 follicles that develop and ovulate. A normal woman usually ovulates 1 follicle a month, and when all the follicles in her body have been ovulated, the function of her ovaries will begin to deteriorate. If you have 3 follicles a month, you may have to face follicle depletion in your 30s and menopause will come early. 2, causing ovarian hyperstimulation syndrome artificially prompted ovaries to ovulate more, the normal body is difficult to withstand this change, easy to trigger ovarian hyperstimulation syndrome, such as dizziness, nausea, causing liver and kidney function damage, etc., and in serious cases, even lead to amputation, shock. This is very dangerous for both the pregnant woman and the fetus. 3, increase the chance of fetal development malformation This is the most worrying adverse consequence for pregnant mothers. The weight of a normal fetus is usually above 2500 grams, while more than half of the twins are below 2500 grams, and some multiple babies even weigh only a few hundred grams. Low weight babies are more likely to have cerebral palsy and mental retardation later in their development.
