One of the most important specialties in medicine is Gynecology and Obstetrics. Gynecology includes treatments involving the female reproductive organs, such as the vulva, vagina, cervix, uterus and tubes. Obstetrics, on the other hand, deals with pregnancy and its follow-up. Also included in this field are female infertility, oocyte monitoring, vaccination, uterine shots, and in vitro fertilization methods.
