support development of fetus
Anatomy of male reproductive structures
testes

Anatomy of female reproductive structures
ovaries

uterine tubes

uterus
nourishes fertilized egg
vagina
serves as birth canal and copopulatory organ
Hormones of the reproductive system
gondadotropin-relasing hormone (GnRh)
stimulates FSH and LH secretion
follicle-stimulating hormone (FSH)
stimulates follicles to grow and secrete sex hormones
luteinizing hormone (LH)
.
testosterone
promotes spermtogenesis
estrogen
promotes oogenesis
progesterone
works with estrogen to regulate uterine cycle
Events of the female hormonal cycles
ovarian cycle
follicular phase(1-14)
1 dominant follicle becomes sensitive to FSH and undergo meiosis to form secondary oocyte
ovulation(14)
ovary wall ruptures expelling secondary oocyte
luteal phase(14-28)
corpus luteum forms and starts to secretes progesterone and estrogen if no pregnancy then corpus luteum becomes corpus albicans
uterine cycle
menstrual phase(1-5)
stratum functionlis detaches and uterine wall is shed
proliferative phase(6-14)
estrogen levels rise to make new stratum functionlis
secretory phase(15-28)
prepares for implantation
Disorders associated with the reproductive system
gonorrhea
bacterial infection
painful urination & discharge
syphilis
bacterial infection
rash & fever
HPV
most common STI
genital warts & usually asymptomatic
