During hormonal control of sperm production, what is the role of LH (ICSH)?
LH (ICSH) stimulates the production of testosterone.
What is the role of testosterone?
Testosterone stimulates the production of sperm in the seminiferous tubules.
It also activates the prostate and seminal vesicles.
During the hormonal control of sperm production, what sort of inhibition takes place?
Negative feedback inhibition.
Which gland in the brain releases FSH and LH (ICSH)?
Pituitary gland.
What is the role of FSH during the menstrual cycle?
FSH stimulates the development of the follicle
It also stimulates the follicle to produce oestrogen

FSH
LH (ICSH)
During the menstrual cycle, which type of hormone stimulates the secretion of FSH and LH (ICSH).

During menstruation, which hormone triggers ovulation ( release of an egg from a follicle)?
LH
During which phase in the ovary is progesterone secreted?
