 Context examples 

The decreased release of LH inhibits ovulation.

(Drospirenone/Ethinyl Estradiol, NCI Thesaurus)

This results in a suppression of LH activity and an inhibition of ovulation as well as an alteration in the cervical mucus and endometrium.

(Drospirenone, NCI Thesaurus)

In males, the inhibition of LH secretion prevents the synthesis of androgens, including testosterone, by the testes.

(Estrogen Receptor Agonist GTx-758, NCI Thesaurus)

The authors note that future studies of the BNST to LH pathways will inform the development of improved therapeutic approaches for psychiatric disorders.

(Researchers identify key brain circuits for reward-seeking and avoidance behavior, National Institutes of Health)

This agent is used for the inhibition of premature LH surges in women undergoing controlled ovarian hyperstimulation, and in combination with other hormones for retrieval of the mature follicles for in-vitro fertilization.

(Ganirelix Acetate, NCI Thesaurus)

The release of luteinizing hormone (LH) is also inhibited, thus preventing ovulation.

(Ethinyl Estradiol/Norgestrel, NCI Thesaurus)

Mimicking the negative feedback mechanism of testosterone, nandrolone decanoate also suppresses the secretion of luteinizing hormone (LH).

(Nandrolone Decanoate, NCI Thesaurus)

Extracts from human menopausal urine containing FOLLICLE STIMULATING HORMONE and LH activity.

(Menotropins, NLM, Medical Subject Headings)

This agent also exerts progestational agonist properties at the level of the pituitary that reduce luteinizing hormone (LH), resulting in reductions in testicular androgen secretion and serum testosterone levels.

(Cyproterone acetate, NCI Thesaurus)

This leads to an alteration in protein synthesis and results in an inhibition of LH release.

(Norethindrone, NCI Thesaurus)
