About 10-15% of all couples attempting to conceive will not become pregnant within one year. Among those, the majority will have ovulatory dysfunction, mild male infertility or unexplained infertility. The traditional first line therapy for those couples is ovulation induction or superovulation using clomiphene citrate. Probably due to anti-estrogenic effects of this agent will, some patients will have a thin endometrium as measured by sonography at the time of ovulation. This phenomenon may be associated with a lower chance to conceive. Tamoxifen is a similar molecule that has been used to clomiphene citrate that has been shown to be equally effective to clomiphene in ovulation induction. Preliminary observations showed that tamoxifen does not cause a negative effect on the endometrium as compared with clomiphene, and may increase the chance to conceive in those patients who have a thin endometrium under clomiphene.

A gonadal stimulant and inducer of ovulation. It is used in the treatment of infertility and amenorrhea, but is thought to be less effective than CLOMIPHENE.
One of the SELECTIVE ESTROGEN RECEPTOR MODULATORS with tissue-specific activities. Tamoxifen acts as an anti-estrogen (inhibiting agent) in the mammary tissue, but as an estrogen (stimulating agent) in cholesterol metabolism, bone density, and cell proliferation in the ENDOMETRIUM.
Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.
An enzyme that, in the presence of ATP and COENZYME A, catalyzes the cleavage of citrate to yield acetyl CoA, oxaloacetate, ADP, and ORTHOPHOSPHATE. This reaction represents an important step in fatty acid biosynthesis. This enzyme was formerly listed as EC 220.127.116.11.
Enzyme that catalyzes the first step of the tricarboxylic acid cycle (CITRIC ACID CYCLE). It catalyzes the reaction of oxaloacetate and acetyl CoA to form citrate and coenzyme A. This enzyme was formerly listed as EC 18.104.22.168.
