Should symptomatic menopausal women be offered hormone therapy?

UNLABELLED: Many physicians remain uncertain about prescribing hormone therapy for symptomatic women at the onset of menopause. The American Society for Reproductive Medicine (ASRM) convened a multidisciplinary group of healthcare providers to discuss the efficacy and risks of hormone therapy for symptomatic women, and to determine whether it would be appropriate to treat women at the onset of menopause who were complaining of menopausal symptoms. MAJOR FINDINGS: Numerous controlled clinical trials consistently demonstrate that hormone therapy, administered via oral, transdermal, or vaginal routes, is the most effective treatment for vasomotor symptoms. Topical vaginal formulations of hormone therapy should be preferred when prescribing solely for the treatment of symptoms of vulvar and vaginal atrophy. Data from the Women's Health Initiative indicate that the overall attributable risk of invasive breast cancer in women receiving estrogen plus progestin was 8 more cases per 10,000 women-years. No increased risk for invasive breast cancer was detected for women who never used hormone therapy in the past or for those receiving estrogen only. Hormone therapy is not effective for the treatment of cardiovascular disease and that the risk of cardiovascular disease with hormone therapy is principally in older women who are considerably postmenopause. CONCLUSIONS: Healthy symptomatic women should be offered the option of hormone therapy for menopausal symptoms. Symptom relief with hormone therapy for many younger women (at the onset of menopause) with menopausal symptoms outweighs the risks and may provide an overall improvement in quality of life. Hormone therapy should be individualized for symptomatic women. This involves tailoring the regimen and dose to individual needs.

Alterations in reproductive function in SRC tyrosine kinase knockout mice.

The role of Src tyrosine kinase in regulating reproductive processes in female mice was investigated using Src wild-type (+/+), heterozygous (+/-), and knockout (-/-) mice. Ovarian Src kinase activity transiently increased in Src +/+ mice following eCG administration. Src knockout mice were infertile. Estrous cycles and vaginal opening in Src knockouts were variable and altered compared with Src +/+ and +/- mice. Follicle development was compromised in Src knockout mice as evidenced by reduced numbers of large pre-antral and antral follicles compared to Src +/+ mice. Corpora lutea were not observed in the ovaries of Src knockout mice; however, administration of eCG and hCG did result in ovulation. Serum LH and FSH on d 40 and 52 of age did not differ between Src wild-type and knockout females. Results from these studies reveal that female Src knockout mice are infertile due to reduced follicle development and anovulation.
