  3. Basic steps in Human Reproduction 1. Gametogenesis 2. Insemination 3. Fertilization 4. Blastocyst development 5. Implantation 6. Embryo development 7. Parturition


  4. Male Reproductive Systerm The 1. Testes 2. Accessory ducts 3. Glands 4. External Genitalia male reproductive system has four main parts:


  5. Testes . Situated in the pelvic region outside the abdominal cavity within a pouch called as scrotum Scrotum is a small muscular sac that contains and protects the testes. It is a part of the external male genitalia and is located behind the penis. .The testes are placed outside the abdominal cavity so as to maintain a temperature that is 2-2.5 C lower than the average human body temperature. . The lower temperature in testes is required for spermatogenesis as the normal human body temperature can lead to mutation in the sperms Testis is oval in shape. It is 4-5cm long and 2-3cm wide. Each testis has about 250 compartments called as Testicular lobules


  6. Ureter- Seminal vesicle Urinary bladder Vas deferens Prostate Penis Urethra Ejaculatory duct Rectum Anus Glans penis Foreskin Testis Scrotum Bulbourethral gland


  7. Spermatic cord This cord contains muscle, blood vessels, nerves, and the vas deferens Vas deferens Epididymis Seminiferous tubule


  8. Each lobule contains 1-3 highly coiled seminiferous tubules . Seminiferous tubules are the site for meiosis that leads to the formation of spermatozoa. e . > The inner lining of each seminiferous tubule consists of two types of cells Spermatogonia and Sertoli cells. Spermatogonia are the immature male germ cells that undergo meiosis that leads to formation of sperms. Each spermatogonium is diploid and contains 46 chromosomes > Sertoli cells provide nutrition to the spermatogonia Interstitial spaces: These are the regions outside the seminiferous tubules. They contain small blood vessels, some immunocompetent cells and interstitial cells or the Leydig cells >Leydig cells: These are the cells that synthesise and secrete testicular hormones called androgens


  9. Sertoli Cell Spermatozoon n lumen Differontiating Meiotic Division I Lurnen Spermatid Leydig Cells Spermatocyte Meiotic Division I Primary Spermalocyle Mitosis Bacal lamina. o0a Basal Lamina pominterous tubule


  10. Accessory Ducts The accessory ducts transport the sperms from the testes to the urethra for their release outside the body. There are tour acesory ducts in the male reproductive system . Rete Testis . Vasa efferentia . Epididymis Vas deferens
