Term
| During puberty in males, the secretion of testosterone increases, what happens because of this? |
|
Definition
| prenatal development of male genitalia and both sperm production and development of male secondary sexual characteristics during puberty |
|
|
Term
| During puberty in females, the secretionof progesterone and estrogen increases, what happens therefore? |
|
Definition
| prenatal development of female reproductive organs and female secondary sexual characteristics during puberty |

|
Term
| What is the first half phase of the menstrual cycle? |
|
Definition
| the follicular phase, is when follicles develop in the ovary. |
|
|
Term
|
Definition
| In each follicle an egg is stimulated to grow. |
|
|
Term
| What is the second half phase of the menstrual cycle? |
|
Definition
| luteal phase, the wall of the follicle that releases an egg becomes a body called the corpus luteum. Continued development of the endometrium prepares it for the implantation of an embryo. |

Term
| Where are the menstrual hormones FSH and LH produced? |
|
Definition
|
|
Term
| Where are the menstrual hormones estrogen and progesterone produced? |
|
Definition
|
|
Term
| What are the 2 functions of FSH (first hormone released in menstrual cycle) |
|
Definition
| stimulates the development of follicles, each containing an oocyte and follicular fluid. FSH also stimulates secretion of estrogen by the follicle wall. |
|
|
Term
| What are the three functions of estrogen (second hormone of the menstrual cycle) |
|
Definition
| stimulates growth of the endometrium, stimulates the release of LH (positive feedback), and inhibites the production of FSH (negative feedback). |
|
|
Term
| What are the two functions os LH (third hormone of the menstrual cycle) |
|
Definition
| stimulates ovulation to happen in the ovaries, stimulates progesterone to be released. |
|
|
Term
| What are the 2 functions of progesterone (fourth and last howmone of the menstrual cycle) |
|
Definition
| endometrium wall is maintained, inhibits LH |
|
|
Term
|
Definition
high doses of FSH and LH are injected daily for 10 days to develop many follicles.
When the follicles are large enough they are stimulated to mature by an injection of HCG, a hormone usually secreted by embryos. The eggs are then washed out of the follicles. Each egg is mixed with 50 – 100 thousand sperm cells and incubated at 370C for 24 hours. then it is put into a woman's uterus. |
