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

How are estrogen & progesterone produced naturally?

How are estrogen & progesterone produced naturally?

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.

After releasing its egg, the follicle becomes a corpus luteum and makes Progesterone instead. ...Read more

Gonadotropin-releasing hormone (gnrh) stimulates the production what?

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

Is estratest (esterified estrogens and methylestosterone) a biochemical hormone?

Is estratest (esterified estrogens and methylestosterone) a biochemical hormone?

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 more

Effectiveness of cervadil vs pitocin (oxytocin) induction?

Effectiveness of cervadil vs pitocin (oxytocin) induction?

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

Does estroven balance hormone levels during peri menopause?

Does estroven balance hormone levels during peri menopause?

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
