Gynaecology or gynecology is the medical practice dealing with the health of the female reproductive systems (vagina, uterus and ovaries), breasts and pregnancy related management. Literally, outside medicine, it means "the science of women". Almost all modern gynaecologists are also obstetricians and therefore the term obstetricians & gynecologists or O&G or OBGYN in short.
