Physiology reproductive

continuation of the species and to pass on your genes "the selfish gene concept"

gonads produce gamates theres 2 types of gamates eggs and sperm

progesterone and estrogen and then androgens

3C degrees less then the rest of the body with help from the cremaster muscle that brings the boys up when its cold and down when its warm to not over heat and denature the soldiers

60% of the total volume of a ejaculation, mainly fructose, capacitation begines here which is the beginning of getting the sperm to be able to be mobile

secretes a antibiotic (seminalplasmin) that cleans out the urethra before ejaculation. 20-30% volume

the antibiotic that the prostate gland releases to kill the bacteria from the urethra.

or cells of leydig creates androgen that then creates testosterone see phone for the picture.

where sperm production takes place, sertoli cells create the sperm cells.

like the blood brain barrier but found in the seminiferous tubules, the immune system will actually attack the sperm cells if they could since they weren't around when the immune system was learning self.

sperm production, stem cells is called spermatongia goes through mitoesis daughter cells A and B 1 stem cell creates 4 sperm.

the maturation of the sperm cells after they are made (so after spermatogenesis

dissolves mucus plug in there external os

antibiotic from the prostate gland

makes the sperm clot up so that it can capacitation 30 minutes after ejaculated it dissolves and the sperm will be all ready to move and fertilize that egg.

breaks down the clot after 30 minutes in the vagina getting used to the environment so that they are capacitation.

the movement of the sperm

aren;t indirect contact with the ovaries, they create currents with a pumping action to suck the egg into the fallopian tube when the egg is ready to ovulate

the most superficial layer of the endometrium, this is what is shed every month during menstruation, responds to ovarian hormones, temporary room and board for sperm.

2nd layer in the endometrium, its the rejuvenating layer it creates the stratum functionalis. it doesn't respond to ovarian hormones

creates the progesterone and estrogen spikes, after the egg is ovulated.

the dead corpus luteum that becomes scar tissue

low estrogen levels inhibit the GnRH from the hypothalamus.

hypothalamus becomes less sensitive (by either the number of receptors increase or a change in recpetors we dont know for sure) to the same amount of estrogen

low percentage of body fat and less menstral cycles big debate if its good or bad to have less or more menstral cycles,

follicular phase (follibrae is creating that current for ovulation) this is different number of days for all woman

luteal phase, this doesn;t differ between woman. if pregnant the corpus luteum stays alive till the babys big enough to take care of the hormones by its self which is 2-3 months. no pregnancy and it lasts 14 days later then dies becomes the corpus albicans
