1. Human Reproduction

2. Outline Male Anatomy Female Anatomy Spermatogenesis Oogenesis
Menstrual Cycle
Fertilization
Pregnancy and Childbirth

4. Male
Organs and tissues testes, seminiferous tubules, epididymis, vas deferens, seminal vescicle, prostate gland Hormones testosterone, FSH, LH Spermatogenesis production of mature sperm by meiosis

5. Male Anatomy

6. Male Anatomy Epididymis Seminal Vesicle Prostate Gland
Storage and maturation of spermatozoa
Seminal Vesicle
60% of semen, high fructose content provides nourishment for sperm, alkaline
Prostate Gland
25% of semen, high zinc content, alkaline, neutralizes acidic female tract

7. Epididymis

9. Testosterone Produced by cells in testes
Embryonic secretion causes development of male sexual organs
Secretion levels rise with onset of puberty
Secondary sexual characteristics
Pubic hair, growth of skeletal muscles, etc.

11. Structure of Testis

12. Sperm Production Termed spermatogenesis, a meiotic division
Occurs in seminiferous tubules of testes
Hormonal Control
Follicle Stimulating Hormone (FSH) / pituitary
Stimulates first division of meiosis (2n -> n)
Testosterone / testes
Stimulates second division of meiosis
Leutenizing Hormone (LH) / pituitary
Stimulates secretion of testosterone

13. Seminiferous Tubule

14. Spermatogenesis

17. `

18. Female
Organs and tissues ovary, oviduct, uterus, cervix, vagina Hormones estrogen, FSH, LH, progesterone, HCG, oxytocin Egg production – oogenesis Menstrual cycle Pregnancy, the placenta, and childbirth
