Knowra Male reproductive system Male reproductive system The organs and structures that produce, transport, and deliver sperm and male sex hormones. Its components include the testes, reproductive ducts, accessory glands, and external genitalia.
Testis : The male gonad that produces sperm and secretes testosterone. Seminiferous tubules inside the testes are where sperm production begins.
Spermatogenesis : The process by which germ cells develop into sperm in the seminiferous tubules. It is the system's central process for producing sperm.
Male infertility : The inability of a male reproductive system to contribute to conception after a period of regular unprotected intercourse. Disruptions in sperm production, transport, or ejaculation can impair fertility.
Female reproductive system : The organs and structures involved in producing ova, supporting fertilization, and enabling pregnancy and birth. It performs complementary reproductive functions using distinct anatomy and gametes.
Seminiferous tubule : A tightly coiled tube in the testis where sperm develop. These tubules house the cells that produce sperm.
Sertoli cell : A supporting cell in seminiferous tubules that nourishes developing sperm and regulates their environment. These cells sustain sperm development and respond to follicle-stimulating hormone.
Semen analysis : A laboratory examination measuring properties of semen, including sperm concentration, motility, and morphology. It assesses sperm-related factors in fertility evaluation.
Urinary system : The organs that produce, store, and excrete urine, including the kidneys, ureters, bladder, and urethra. The male urethra serves both urinary and reproductive functions, unlike most urinary structures.
Epididymis : A long, coiled duct on the back of each testis where sperm mature and are stored. Sperm acquire motility and fertilizing capacity as they pass through this duct.
Leydig cell : A testicular cell that produces testosterone in response to luteinizing hormone. Testosterone from these cells supports sperm production and male reproductive functions.
