Abstract: The goal ofpostmenopausal hormone therapy is to alleviate the symptoms that are associated with the loss of estrogen. Many formulations of estrogen and progestin are available, depending on the needs and circumstances of each individual woman. For postmenopausal women, the choice of whether or not to begin therapy requires knowledge of the risks and benefits of estrogen and/or progest...

Estrous synchronization and artificial insemination have potential to increase the rate of genetic improvement, calf uniformity and improve calf weaning weight in beef cattle operations. Synchronization programs utilizing exogenous progestins, gonadotropin releasing hormone (GnRH), and prostaglandin (PGF 2 α) have been shown to be effective for estrous synchronization in beef cows and heifers (...

There is some evidence that women with a higher number of CAG repeat lengths on the androgen receptor (AR) gene have increased breast cancer risk. We evaluated the association between AR-CAG repeat length and mammographic density, a strong breast cancer risk factor, in 404 African-American and Caucasian breast cancer patients. In postmenopausal estrogen progestin therapy users, carriers of the ...

Endometrial cancer contains estrogen and progestin receptor proteins. The receptor content inversely correlates with histologic differentiation. The correlation between receptor content and histologic subtype and stage of the disease may depend upon the degree of differentiation of the tumor. The status of the peritoneal cytology and depth of myometrial invasion by tumor do not correlate with t...

Objective: To examine the relationship between progestin-only contraception and breast cancer, and to make recommendations regarding contraception for the breast cancer survivor. Outcome: Incidence of breast cancer among users of progestin-only contraception. Evidence: PubMed and Medline databases were searched using the terms “breast cancer” and “progesterone,” “contraception,” “depot medroxyp...

Abstract Study question Could exogenous progestin replace the use of an antagonist GnRH (GNRH-antagonist) without any effects on embryo morphokinetics and implantation rate in freeze-all cycles? Summary answer Exogenous leads to slower development increased cyclés cancellation rate, with when compared cycles using GnRH-antagonist. What is known already Improvements cryopreservation techniques a...

The key message on the use of unopposed estrogen and estrogen plus progestin after menopause is clear: increased risks of stroke, coronary heart disease, pulmonary embolism, and breast cancer outweigh reduced risks of fractures and colorectal cancer. Individual riskbenefit profiles will, of course, vary, but current clinical guidelines emphasize use for symptom relief only, at low doses and for...
