G
GALACTORRHOEA
A clear or milky discharge from the breasts associated with
elevated prolactin.
GAMETE
A reproductive cell: Sperm in men, the egg in women.
GAMETE
INTRAFALLOPIAN TRANSFER (GIFT) A technique that may
be used in lieu of in vitro fertilisation for women with
patent (clear and open) tubes. After egg retrieval the eggs
are mixed with the husbands sperm and then injected through
the fimbria into the womans fallopian tubes for in vivo
fertilisation.
GERM
CELL In the male the testicular cell that divides to
produce the immature sperm cells; in the woman the ovarian
cell that divides to form the egg (ovum). The male germ
cell remains intact throughout the mans reproductive life;
the woman uses up her germ cells at the rate of about one
thousand per menstrual cycle, although usually only one
egg matures each cycle.
GERM
CELL APLASIA (SERTOLI CELL ONLY) An inherited condition
in which the testicles have no germ cells. Since men with
this condition have normal Leydig cells, they will develop
secondary sex characteristics. May also be caused by large
and/or prolonged exposure to toxins or radiation.
GONAD
The gland that makes reproductive cells and "sex"
hormones: the testicles, which make sperm and testosterone,
and the ovaries, which make eggs (ova) and estrogen.
GONADOTROPINS
Hormones which control reproductive function: Follicle Stimulating
Hormone and Lutenizing Hormone.
GONADOTROPIN
RELEASING HORMONE (GNRH) The hormone which controls
the production and release of gonadotropins. Secreted by
the hypothalamus every ninety minutes or so, this hormone
enables the pituitary to secrete LH and FSH, which stimulate
the gonads. See FSH,LH.
