The field cooperates with and overlaps mainly with reproductive endocrinology and infertility, sexual medicine and andrology, but also to some degree with gynecology, obstetrics, urology, genitourinary medicine, medical endocrinology, pediatric endocrinology, genetics, and psychiatry. Reproductive medicine is a branch of medicine that deals with prevention, diagnosis and management of reproductive problems; goals include improving or maintaining reproductive health and allowing people to have children at a time of their choosing. It is founded on knowledge of reproductive anatomy, physiology, and endocrinology, and incorporates relevant aspects of molecular biology, biochemistry and pathology. It addresses issues of sexual education, puberty, family planning, birth control, infertility, reproductive system disease (including sexually transmitted diseases) and sexual dysfunction. In women, reproductive medicine also covers menstruation, ovulation, pregnancy and menopause, as well as gynaecologic disorders that affect fertility.
