Organs Hormonal Control

2. Male Reproductive System
Seminal vesicle: fructose, prostaglandins for semen
Penis: erectile organ
Prostate gland: alkaline secretion for semen
Urethra: exit tube for semen
Bulbourethral gland: mucoid fluid for semen
Vas Deferens: sperm transport
Epididymis: sperm maturation
Scrotum: suspends testes
Testis: sperm production

3. Sperm Formation Site of sperm production within testis
Contains enzymes for digesting through the egg’s protective coat
Contains chromosomes
Has mitochondria for energy release
For movement

4. Hormonal Regulation in Males
Gonadotropin Releasing Hormone stimulates Pituitary to release LH, FSH
Follicle Stimulating Hormone
Luteinizing Hormone
Negative feedback to pituitary & hypothalamus
Negative feedback to pituitary & hypothalamus
Male sex characteristics

5. Applying Your Knowledge
Epididymis
Prostate Gland
Testis
Urethra
Vas Deferens
Which one produces an alkaline secretion as part of semen?
From which one do sperm exit the body?
Where are sperm produced? 2 4 3

6. Female Reproductive System
Fallopian tube: egg transport, site of fertilization
Ovary: egg production
Uterus: site of fetal development
Female Reproductive System
Vagina: birth canal, exit for menstrual flow, site of sexual intercourse
Clitoris: erectile organ

7. Ovarian Cycle immature egg
1. Primary follicles contain oocyte and begin producing the sex hormone estrogen

8. Hormonal Regulation in Females
Stimulates Pituitary to release FSH, LH
Follicle Stimulating Hormone: development of follicle, containing egg
Luteinizing Hormone: controls ovulation, development of corpus luteum
Estrogen: produced in ovary, stimulates thickening and vascularization of uterine lining
Progesterone: produced in ovary, stimulates increased thickening of uterine lining
Estrogen and Progesterone exert negative feedback on hypothalamus and pituitary
Female sex characteristics

9. Hormone Levels in Ovarian and Uterine Cycles

10. Fertilization and Implantation
Fertilization: Sperm enters egg
Implantation: embryo attaches to uterine lining

11. Applying Your KnowledgeLH

Testosterone
Which hormone stimulates egg development?
Which hormone stimulates sperm development?
Which hormone maintains the buildup of the uterine lining? 2 2 4
