Prostaglandins
Where the fetus develops, aka the womb
Uterus
Another organ that forms in the uterus during pregnancy
Placenta
the female sex organ that produces eggs and hormones
Ovary
The expulsion of semen from the penis
Ejaculation
The release of an egg on day 14 in the cycle due to a surge in luteinizing hormone
Ovulation
The ejaculatory ___ carries semen from the seminal vesicles to the urethra

Progesterone
Ovulation occurs in response to
A surge of estrogen
HCG hormone is produced by a newly implanted embryo, sending a signal to the _______ to continue producing progesterone to maintain the uterine lining.
Corpus luteum
LH has the function of
causing Ovaries/Testes to produce Estrogen/Testosterone
FSH has the function of
Causes the follicle in the ovary to develop, and acts on the Sertoli cells to produce sperm
Progesterone has the function of
Prepares the endometrium for implant, most common during the second stage of the menstruation cycle
GnRH has the function of
stimulates the anterior pituitary gland to release LH
HCG has the function of
Maintaining hormone balance
What is at the head of the sperm so it can penetrate the egg?
Acrosome
The Seminal vesicles secrete (2 things)
Fructose (Acts as energy for the sperm), Prostaglandins (cause uterine contractions which help propel the sperm towards the egg.)
A hormone that indicates sperm levels. Lots of this hormone causes the slow of sperm production
Inhibin
Where is sperm stored? (2 places)
Epididymis and vas deferens
