like bunches of grapes between the seminiferous tubules in which sperms are produced.; the
interstital cells in the testes that produce testosterone; they are packed between the
seminiferous tubules in which the sperms grow.
LH (luteinizing hormone): a gonadotropin secreted by the anterior lobe of
the pituitary gland that stimulates testosterone secretion from the testis, in the male,
and the formation of the corpus luteum and the secretion of progesterone from the ovary,
in the female; one of the gonadotropic hormones of the pituitary gland. It induces release
of the egg from the graafian follicle and transformation of the latter into a corpus
luteum. LH in the female is the same as ICSH (interstitial cell stimulating hormone),
which stimulates testosterone production in the male; see also FSH.
LHRH (luteinizing hormone-releasing hormone): from the hypothalamus, a
hormone that triggers the release of the pituitary gonadotropins, LH and FSH. LH frees the
