The main reason why twins are more likely to be born when oral ovulation drugs are taken is that normally, one follicle will develop and expel an egg each month, so the majority of pregnancies are singleton pregnancies. If you take ovulation medication, you may have more than one follicle growing, developing and expelling more than one egg, which is more likely to result in twins in clinical practice. However, there are indications and contraindications for ovulation stimulating drugs. Before taking them, it is important to know whether the ovaries are ovulating or not. If there is natural ovulation, ovulation-promoting drugs should not be used to avoid ovarian overstimulation. In addition, if the drug is not applied properly, it may lead to premature ovarian failure, so be sure to use the drug under the guidance of a doctor.
