Human Reproduction Flashcards
testicle
- the production of sperm
- secrete testosterone
scrotum
layer of skin around the testicle
- protects testicle
- temp control in the sperm
germinal epithelium
seminiferous tubules are lined with special cells
seminiferous tubules
*
epididymis
store sperm temporarily
penis
- insures that internal fertilisation takes place
- release of semen
prostate gland (just below bladder)
-neutralises the pH of the vagina
seminal vessicle
-releases sugar (fructose)
use sugar in order to produce energy - sperm can swim
Cowper’s gland
below prostate gland
- acts as lubricant to help sperm swim faster
- releases a liquid prior to ejaculation to clear the urethra of any residual urine
urethra
- urination
- ejaculation
sertoli cells
germinal epithelium cells develop into larger columnar cells
leidig cells
*
sperm
a structure that carries the male gametes
semen
sperm + glandular liquids
ovary
- produces egg cells
- releases oestrogen - released by follicle
- releases progesterone - released by corpus luteum
ejaculation
release of sperm
erection
*
fallopian tubes / oviduct
- fertilisation takes place
- contracts and relaxes (makes peristalsis movements) - pushes egg cells towards uterus
uterus
- embryo develops
- contract during birthing process (push baby into vag)
cervix
- protects uterus against infection
- during birth - dialate about 10 cm so that baby’s head can pass
endometrium
- required for implantation (blastocyst attaches to endometrium)
- once that happens, form part of placenta
vagina
- serves as birth canal
- semen will be released during internal fertilisation
condoms
prevent STI’s
Diaphragm
prevents sperm from entering uterus
IUD
prevents implantation
morning after pill
delays ovulation
birth control pill/patch (contraceptive)
prevens ovulation
-synthetic progesterone inhibts FSH and LH
vasectomy
prevents sperm from reaching urethra
rhythm method
having sex on “safe days”
tubal ligation
prevents fertilisation
spermicide
kills sperm
