  1. Andrologi

  2. Pengertian • Andrologi (dari bahasa Yunani andros yang berarti laki-laki) adalah spesialisasi medis yang berhubungan dengan kesehatan pria, secara khusus kepada masalah-masalah yang berhubungan dengan sistem reproduksi dan sistem urin pria. • Andrologi merupakan lawan dari ginekologi yang menangani masalah kesehatan wanita

  3. Testis terbungkus di suatu kantong di luar rongga tubuh yang disebut skrotum. • Tempat produksi sperma di dalam testis adalah di tubulus seminiferus. • Dalam setiap testis terdapat sekitar 250 meter tubulus seminiferus • Produksi sperma dimulai setelah usia dewasa • Pematangan dan penyimpanan sementara sperma di dalam epididimis.

  4. Struktur Alat Reproduksi Pria • Sperm pass through the vas deferens and connect to a short ejaculatory duct that connects to the urethra. The urethra passes through the penis and opens to the outside. Secretions from the seminal vesicles add fructose and prostaglandins to sperm as they pass. The prostate gland secretes a milky alkaline fluid. The bulbourethral gland secretes a mucus-like fluid that provides lubrication for intercourse. Sperm and secretions make up semen.

  5. Hormon Reproduksi Pria • The anterior pituitary produces follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Action of LH is controlled by the gonadotropin-releasing hormone (GnRH). LH stimulates cells in the seminiferous tubules to secrete testosterone, which has a role in sperm production and developing male secondary sex characteristics. FSH acts on cells to help in sperm maturation. Negative feedback by testosterone controls the actions of GnRH
