__**Reproduction System Notes**__

(1) When is an individual capable of producing children? (2) Where are sperm produced? (3) Where are eggs produced? (4) How many chromosomes does the mother contribute via the egg to the new individual? (5) How many chromosomes does the father contributed via the sperm to the new individual? (6) What male structures are involved in the making of seminal fluid? (7) Describe the cells and structures involved in making mature sperm. (8) Which hormones control the male reproductive cycle? Describe the function of each. (9) Describe the function of the ovaries, oviducts, uterus, cervix, and vagina. (10) Which hormones control the female reproductive cycle? Describe the function of each.
 * At the completion of puberty
 * it is produced by the testes and mature within the **epididymis**
 * the ovaries
 * 23
 * 23
 * **seminal vesicles**
 * **prostate gland**
 * **bulbourethral glands**
 * **spermatogonia** divides and produces primary **spermatocytes** that moved away from the outer wall in the **seminiferous tubules** and increases in size and goes through meiosis I which produces secondary spermatocytes.
 * Meisis II the spermatocytes produce four spermatids each of which have 23 chromosomes
 * It takes 74 days for a sperm to undergo development from spermatogonia to sperm
 * **gonadotropin-releasing hormone** which stimulates the anterior pituitary to secrete the gonadotropic hormones
 * //follicle-stimulating hormone// promotes the production of sperm in the seminiferous tubules
 * //luteinizing hormone// controls the production of testosterone by the interstitial cells
 * Testosterone is essential for the normal development and functioning of organs and also brings about and maintains the male secondary sex characteristics that develop at the time of puberty
 * **ovaries**- produce eggs and sex hormones
 * **oviducts**- conduct eggs and location of fertilization
 * **uterus**(womb)-housing developing for fetus
 * **cervix**-contains opening to uterus
 * **vagina**-recieves penis during sex and serves as birth canal and as an exit for menstrual flow
 * **Estrogen**- is made in the ovaries and the signal is to mature an egg
 * not released until puberty and stops making estrogen during menopause
 * 2 weeks out of every menstrual cycle estrogen is released by the ovary
 * **Progesterone**- is made in the ovary by the empty egg sac and made from puberty until menopause
 * is released the last 2 weeks of the menstrual cycle
 * the receptors are found in the womb (uterus) and keeps the lining of the uterus thick
