Andrology is the branch of medicine and biology that concentrates on male health, with particular emphasis on the reproductive system and sexual function. It overlaps with urology, endocrinology and reproductive medicine and addresses conditions such as erectile dysfunction, infertility, low testosterone, congenital or acquired disorders of the testes and penis, and certain infections. Andrology complements but differs from gynecology, which focuses on female reproductive health.
Scope and key topics
The field covers diagnosis, treatment and research into male fertility (including semen quality and sperm function), sexual dysfunction, hormonal evaluation and management, and surgical or medical interventions. Preventive care and counseling—on lifestyle, contraception choices and genetic risks—are increasingly part of andrological practice. Andrology also examines how systemic diseases and aging affect male reproductive health.
Anatomy, diagnosis and clinical methods
Practitioners use clinical examination and a range of tests to evaluate patients. Typical assessments include hormonal blood tests, semen analysis, imaging (such as ultrasound), specialized sperm function tests, and measurements of erectile physiology when appropriate. Treatments may be medical (hormone replacement, phosphodiesterase inhibitors), assisted reproductive technologies, microsurgery, or behavioral and rehabilitative approaches.
History and development
Although doctors have long treated male reproductive conditions, andrology emerged as a distinct discipline in the mid-20th century. The specialty gained formal recognition and dedicated literature from the late 1960s onward; early specialist journals helped consolidate research and clinical practice in the decades that followed. See historical summaries and journal records for more detail: foundational background, the German periodical Andrologie and its publication notes publication history.
Public health and notable distinctions
Andrology intersects with public health because some male-specific patterns of disease influence reproductive health. For example, men generally have different cardiovascular risk profiles and life expectancy patterns compared with women, which can affect sexual function and fertility; readers can consult resources on cardiovascular risks for context. Conversely, conditions such as osteoporosis are less common in men than women, but remain clinically relevant in older patients: see summaries on bone health.
Research directions and clinical importance
Current research in andrology spans basic studies of spermatogenesis and hormone action, improvements in male contraception, refinement of assisted reproduction techniques, and the longer-term effects of environmental and lifestyle factors on male reproductive potential. As awareness grows, many health systems are integrating andrological services into broader men's health programs to improve outcomes and access to care.
