FSH,LH: Gnrh stimulates follicle stimulating hormone & luteinizing hormone which stimulates the ovary to produce estrogen and Progesterone which stimulates ovulation which causes increased Progesterone which causes secretory endometrium which prepares the endometrium to allow implantation of a fertilized egg. If no fertilized egg, Progesterone falls which stimulates gnrh to again rise & the cycle repeats. ...Read more
Interesting question: Nocturnal secretion of melatonin has been shown to affect secretion of prolactin. To my knowledge melatonin can exacerbate mild hyperprolactinemia. The relationship between Progesterone and prolactin i think is more unclear. We know thatprogesterone can affect prolactin in various ways. I'm curious to know in what context you would like to know the answer to this question? ...Read more
By the follicle: An amazing dance of hormones coordinates the reproductive system. One of the thousands of egg sacs that are in the ovary matures each month during the reproductive years. During the first two weeks of the menstrual cycle, the follicle releases estradiol, a potent estrogen. After releasing its egg, the follicle becomes a corpus luteum and makes Progesterone instead. ...Read moreSee 1 more doctor answer
Good question: Gnrh would seem by its name to help release gonadotropin. And if used in a certain fashion it could cause the release of gonadotropins (lh, fsh). However when given in a shot and having a sustained effect on the pituitary, it actually suppresses the release of lh and fsh. And this aspect of the medication can be used to help in many situations. ...Read more
Yes...: ...But perhaps you mean bioidentical. All hormones are biochemicals. Estratest (esterified estrogens and methylestosterone) is a combination of methyltestosteone, which is synthetic and not the same as your own testosterone, and mixed estrogen hormones which are excreted by pregnant mares in their urine. These hormones are similar to, but not identical to, natural human hormones. ...Read moreSee 1 more doctor answer
Depends on cervix: Before induction your current cervical exam is used as a determinant for which mode of induction. Cervidil is most likely used when the cervix is less soft, dilated, and effaced (thinned out), and more posterior, as it increases prostaglandins release to stimulate dilation, thinning and softening. Those who are already dilated and effaced benefit more from pitocin (oxytocin). ...Read more
For some yes: Estroven is an over the counter herbal supplement to improve hormonal imbalance during perimenopause. It can help women who have mild symptoms and are good candidates for hormone use. (a poor candidate are women with heart disease, diabetes, cancers, blood clots). If you have severe symptoms, this will not help and you can consider bio identical hormone replacement. ...Read more
Tamoxifen is given to breast cancer patients to suppress estrogen or both estrogen & progesterone?
Estrogen: Tamoxifen is given to individuals with specific breast cancers that are driven to grow by the presence of estrogen receptors. Tamoxifen interferes with the activity of estrogen in the breast, preventing cancer growth. The role of Progesterone receptors is unclear, though Progesterone receptors in breast cancer are generally associated with estrogen receptors, making tamoxifen an effective therapy. ...Read moreSee 2 more doctor answers
No: Premarin (conjugated estrogens), (conjugated estrogens) a synthetic estrogen, is prescribed for menopausal symptoms such as hot flashes, vaginal dryness, anxiety etc. It can actually increase vaginal bleeding.
