Or to be more precise, a woman has 3.3 percent chance of conceiving twins naturally. By naturally, we mean without any kind of fertility treatment.

Ectopic pregnancy is any pregnancy in which the fertilized ovum implants outside the intrauterine cavity.

Other causes of infertility include poor sperm quality, sperm not moving well (poor motility), or not having enough (or any) sperm to begin with.

An over-the-counter ovulation prediction kit — a test that you can perform at home — detects the surge in luteinizing hormone (LH) that occurs before ovulation.

Extra-uterine growth is affected by the patient's monthly hormonal cycle. The resulting bleeding does not have an exit route.

It can be managed medically with simple medication, such as bromocriptine and cabergoline, which normalizes serum prolactin levels, restoration of gonadal function, reversing infertility caused by hyperprolactinemia and induces reduction in the prolactinoma size in the majority of patients.
