- prostaglandins- chemicals in the body that makes the smooth muscle in the uterus contract.
- implantation- (a process) Progesterone, another hormone released by the ovaries, keeps the endometrium thick with blood so that the blastocyst can attach to the uterus and absorb nutrients from it.
- vulvovaginitis-an inflammation of the vulva and vagina. It may be caused by irritating substances (such as laundry soaps or bubble baths). Poor personal hygiene (such as wiping from back to front after a bowel movement) may also cause this problem.
I heard that there is a such thing called menstrual problems and alot of them affect girls.
Here are some that is most common:
- dysmenorrhea (pronounced: dis-meh-nuh-ree-uh) when a girl has painful periods.
- menorrhagia (pronounced: meh-nuh-rah-zhuh) when a girl has a very heavy periods with excess bleeding.
- oligomenorrhea (pronounced: o-lih-go-meh-nuh-ree-uh) when a girl misses or has infrequent periods, even though she's been menstruating for a while and isn't pregnant.
- amenorrhea (pronounced: a-meh-nuh-ree-uh) when a girl hasn't started her period by the time she is 16 years old or 3 years after starting puberty, has not developed signs of puberty by age 14, or has had normal periods but has stopped menstruating for some reason other than pregnancy.
I noticed that alot of things can go wrong in the female anatomy system. For an example, nonmenstrual vaginal bleeding is due to urethral prolapse, a condition in which the mucous membranes of the urethra protrude into the vagina and form a tiny, donut-shaped mass of tissue that bleeds easily. It can also be caused by a minor injury (such as when falling onto a beam or bicycle frame) or vaginal trauma from sexual abuse.
I wonder why does so many things occur in the female anatomy system more than in the male anatomy system?
