Almost all types of hormonal birth control switch off ovarian function and, therefore, switch off the ovarian hormones estradiol, testosterone, and progesterone. Here’s a bit more about each method.
hormone therapy
Body-identical or bioidentical menopausal hormone therapy uses hormones that are exactly identical to human hormones. Bioidentical hormones are safer than other types of hormone replacement, both in terms of cardiovascular risk and breast cancer risk. Examples include transdermal estradiol patches and oral micronized progesterone.
How Science Got It Wrong About Progesterone
Progesterone has been both ignored and mistakenly blamed for side effects it does not cause. How did that happen?
For one thing, progesterone was discovered shortly after estrogen. Thus missing out on the tidy hormone dichotomy of “testosterone for men and estrogen for women.” Also, progesterone could not (at first) be made into a medication that could be absorbed orally.
How Too Much Testosterone Can Cause Weight Gain in Women
In women, too much testosterone can cause insulin resistance and abdominal weight gain.
That’s why androgen excess is the main driver of weight gain with polycystic ovary syndrome (PCOS), menopause, and some types of birth control.
High Histamine Can Make for a Tougher Perimenopause
A tendency to allergies or high histamine can increase the risk of perimenopausal symptoms such as night sweats, anxiety, pain, sleep disturbance, migraines, and heavy periods. That’s because histamine increases with estrogen, and estrogen is higher than normal during the early years of perimenopause.
