hormones causing twins
HCG can cause early puberty in young boys. Call your doctor if a boy using this medicine shows early signs of puberty, such as a deepened voice, pubic hair growth, and increased acne or sweating. Using HCG can increase your chances of having a multiple pregnancy (twins, triplets, quadruplets, etc).
What is HCG? Human chorionic gonadotropin (HCG) is a hormone that supports the normal development of an egg in a woman's ovary, and stimulates the release of the egg during ovulation. HCG is used to cause ovulation and to treat infertility in women, and to increase sperm count in men.
