Which are the hormones responsible for secondary sex characteristics?

The Leydig cells produce testosterone, which also is responsible for the secondary sexual characteristics of males. In females, FSH and LH cause estrogen and progesterone to be produced.

FSH (follicle-stimulating hormone)

a hormone secreted by the anterior pituitary gland that promotes the formation of ova or sperm.

Where does sperm travel during ejaculation?

ductus deferens

Where is sperm stored?

epididymis

Which hormones are responsible for maintaining pregnancy?

estrogen and progesterone

Which hormones are responsible for the menstrual cycle?

estrogen, progesterone, follicle stimulating hormone (FSH), and luteinizing hormone

fertilization

fusion of the nuclear material of the egg & sperm

Where is sperm produced?

testes, specifically the seminiferous tubules

LH (leutinizing hormone)

a hormone secreted by the anterior pituitary gland that stimulates ovulation in females and the synthesis of androgen in males.

progesterone

a steroid hormone released by the corpus luteum that stimulates the uterus to prepare for pregnancy.

Testosterone

a steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex.

meiosis

cell division resulting in 4 daughter cells each w/half the chromosomes of the parent cells *occurs mostly in the gonads

Pathway of sperm

epididymis, ductus deferens, (ejaculatory duct), urethra
