5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Fertility Agents, Female

Compounds which increase the capacity to conceive in females. (See all compounds classified as Fertility Agents, Female.)


Estrogen Antagonists

Compounds which inhibit or antagonize the action or biosynthesis of estrogenic compounds. (See all compounds classified as Estrogen Antagonists.)


Selective Estrogen Receptor Modulators

A structurally diverse group of compounds distinguished from ESTROGENS by their ability to bind and activate ESTROGEN RECEPTORS but act as either an agonist or antagonist depending on the tissue type and hormonal milieu. They are classified as either first generation because they demonstrate estrogen agonist properties in the ENDOMETRIUM or second generation based on their patterns of tissue specificity. (Horm Res 1997;48:155-63) (See all compounds classified as Selective Estrogen Receptor Modulators.)
