Reproduction Study Guide
Hormone / Stimulated by / Function in Females / Function in MalesGonadotropin Releasing Hormone (GnRH) / · Low E and P (females)
· Puberty (males) / Releases FSH and LH / Releases FSH and LH
Follicle Stimulating Hormone (FSH) / GnRH / · Matures egg
· Release E and P / Sperm production
Luteinizing Hormone (LH) / GnRH / · Egg prepares for release
· Release E and P / Releases testosterone
Estrogen and Progesterone / · FSH and LH
· Corpus Luteum
· HCG / Thickens the endometrium /
Human Chorionic Gonadotropin (HCG) / Placenta formation / Releases E and P
Oxytocin / Baby dropping / · Uterus contractions
· Milk production
Testosterone / LH / / Secondary sex characteristics
Egg Does Not Get Fertilized:
Start of Menstrual Cycle: low levels of estrogen and progesterone
1. Gonadotropin Releasing Hormone (GnRH) released
2. Follicle Stimulating Hormone (FSH) released: causes egg to mature in follicle
3. Luteinizing Hormone (LH) released: causes egg to burst from follicle
4. FSH and LH stimulate release of estrogen and progesterone
5. Endometrium thickens
6. Egg released in a process called ovulation
7. Corpus luteum, or ruptured follicle, releases estrogen and progesterone
8. Egg does not get fertilized.
9. Corpus luteum breaks down.
10. Levels of estrogen and progesterone decline.
11. Endometrium breaks down
12. Menstrual flow
Egg Gets Fertilized:
Start of Menstrual Cycle: low levels of estrogen and progesterone
1. Gonadotropin Releasing Hormone (GnRH) released
2. Follicle Stimulating Hormone (FSH) released: causes egg to mature in follicle
3. Luteinizing Hormone (LH) released: causes egg to burst from follicle
4. FSH and LH stimulate release of estrogen and progesterone
5. Endometrium thickens
6. Egg released in a process called ovulation
7. Corpus luteum, or ruptured follicle, releases estrogen and progesterone
8. Egg is fertilized in fallopian tube
9. Mitosis occurs to make more cells and form an embryo.
10. Embryo implants in uterus and forms a placenta
11. Human Chorionic Gonadotropin (HCG) released and detected in pregnancy tests.
12. Releases more estrogen and progesterone
13. Endometrium thickens
14. After 40 weeks, oxytocin stimulates uterus to contract and baby pushed out
15. The placenta separates from the uterine wall and is expelled.
16. Levels of estrogen and progesterone decline.
Male Reproductive System
Reproductive Part / FunctionSeminiferous Tubules (Testes) / Produce sperm
Scrotum / Regulates temperature of testes
Epididymis / Matures and stores sperm
Vas Deferens / Transports sperm out of testes
Prostate Gland / Produce seminal fluid
Seminal Vesicles / Produce seminal fluid
Urethra / Release semen from body
