Gynaecology (or gynecology in American English) is the area of medicine concerned with conditions affecting the female reproductive system. It is sometimes combined with the field of obstetrics, which focuses on pregnancy and childbirth, thereby forming the combined area of obstetrics and gynaecology (OB-GYN).
Gynaecology encompasses preventative care, sexual health and diagnosing and treating health issues arising from the female reproduction system, such as the uterus, vagina, cervix, fallopian tubes, ovaries, and breasts; subspecialties include family planning; minimally invasive surgery; paediatric and adolescent gynaecology; and pelvic medicine and reconstructive surgery. Transgender, intersex and nonbinary individuals can in some instances require gynaecological care.
