Overview of Ovaries and Testes in the Human Reproductive System

The ovary, pear-shaped and part of the female reproductive system, plays crucial roles in the production of oocytes and hormones. It is connected to mesenteries and lined with germinal epithelium, featuring different stages of Graafian follicles. In contrast, the testis is a key component of the male reproductive system, responsible for sperm and testosterone production. Encased by tunica albuginea, each testis consists of seminiferous tubules and interstitial cells, with stages of sperm maturation, including spermatogenic cells and Sertoli cells, which provide support.

Presentation Transcript

  1. Reproductive system Biology 106

  2. Ovary • it’s a part of female reproductive system. • Pear in shape • The ovaries have two functions - "production" and ovulation of oocytes and the production and secretion of hormones.

  3. Structure of Ovary • Connected to the mesenteries by hilum • Surrounded by peritoneal epithelium (simple squamous epithelium) • Lined with germinal epithelium

  4. Have different stages of GraafianFollicle: • oogonia, • primary oocyte, • secondary oocyte, • mature ovum in the Graafian Follicle)

  5. Have Corpus luteum(the remnant tissues after discharging of mature ovum and secrete some hormones the beginning of the pregnancy for its stability)

  6. Testis • It is part of male reproductive system • Its a gland where sperms and male hormones ( testosterone) are produce.

  7. The structure of testis Each testis is covered by a layer of white fibrous connective tissue called tunica albuginea. The testis is formed of seminiferous tubules,interstitial cells and blood vessels.

  8. The seminiferous tubules are long and coiled tubes. Contain of these types of cells: • spermatogeniccells. • Primay spermatocyte • Secondary spermatocyte • Spermatids • Spermatozoa • Sertoli cells: Found in between the different stages of maturation of sperm for nutrition and support

  9. Any questions ??
