Ch. 8: Reproductive Function Flashcards
(130 cards)
stores sperm
epididymides
conduct sperm to the urethra
vans deferens
produce seminal fluid that nourishes sperm
sex accessory glands
provides proper temperature for the testes
scrotum
the inner mucosal lining of the uterus which undergoes hormonal changes to facilitate and maintain pregnancy
endometrium
the middle layer of the uterus which is made up of smooth muscle and a vascular system
myometrium
the outer serous layer of the uterus that covers all of the fundus and part of the corpus, but none of the cervix
perimetrium
inability to contribute to reproduction
infertility
what are male problems that can cause infertility?
decreased sperm or sperm abnormalities, hormone deviations, physical impediments
what are female problems that cause infertility?
ovulation dysfunction, hormone deviations, physical obstructions (usually in the Fallopian tubes), severe reproductive tract infections
anatomical defect in which the urethral meatus occurs on the dorsal surface of the penis and may extend the entire length of the penis in males and where the urethral meatus may be placed in the clitoris in females
epispadias
what problems is epispadias likely to cause?
urinary tract infections, urination problems (usually in men), sexual dysfunction (usually in women)
why may epispadias cause reproductive problems in men?
they may have trouble propelling the sperm when they ejaculate
condition in which the urethral meatus is on the ventral surface of the penis instead of the end. the opening can extend the length of the penis. males with this condition may have chordee
hypospadias
downward curvature of the penis that occurs with hypospadias and is most apparent when the patient has an erection
chordee. can be painful and need surgical correction
occurs when the foreskin cannot be retracted from the glans penis
phimosis
when is phimosis normal?
during the first three years of age, but the foreskin should become retractable as the child grows
what things can lead to phimosis?
poor hygiene, infections, inflammation, they could be born with a defect in which the skin is just too tight
what complications can arise because of phimosis?
could cover the urethral meatus and cause a urinary obstruction, and cause a lot of pain
when the foreskin is retracted and cannot be returned over the glans penis
paraphimosis
what occurs when the foreskin cannot be returned to the glans penis?
the penis becomes constricted and the glans becomes edematous. lack of blood flow can lead to gangrene, making it a medical emergency
prolonged, painful erection that is not the result of sexual stimulation
priapism
what are the two things that priapism can result from?
from too much blood shunting within the corpus cavernosum (nonischemic or high-flow priapism) or from blood becoming trapped in the penis (ischemic or low-flow priapism)
at what ages is priapism most common?
5-10 and 20-50
