GlossaryGonadotropin-Releasing Hormone Agonists

medications that initially boost, then suppress, sex hormone production

Gonadotropin-Releasing Hormone Agonists (GnRH agonists) are medications that mimic the natural hormone GnRH, which regulates the release of other hormones like luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. Initially, they increase the production of these hormones, but with continuous use, they suppress their release, leading to reduced levels of sex hormones such as testosterone and estrogen. This makes them useful in treating hormone-sensitive conditions like prostate cancer, endometriosis, and certain types of breast cancer.

community My Estradiol Level on Finasteride

in Research/Science 17 upvotes 1 year ago

Finasteride has no effect on the user's estradiol levels, and body fat may influence aromatization. The user is on testosterone replacement therapy and uses everyday injections to manage high RBC count, with plans to measure DHT, DHEA-S, and pregnenolone levels.

community My Testosterone is less than 1/3rd In 7 Months since I took Finasteride!

in Finasteride/Dutasteride 117 upvotes 3 years ago

A user experienced a significant drop in testosterone levels after taking finasteride, leading to side effects like low libido and muscle mass loss. Despite its effectiveness for hair, the user decided to stop finasteride due to its impact on hormones, preferring to be bald.

community 35 MtF | 16 Months | Minoxidil + Dutasteride + Microneedling + Exosomes. Note that since I'm early in my transition (and I was coming from a bald state), I still have short hair. Very few MtF progress pictures here, I figure this might help some of you.

in Transgender 125 upvotes 2 years ago

A 35-year-old transitioning female (MtF) shared her hair regrowth journey using Minoxidil, Dutasteride, Microneedling, and Exosomes, starting from a bald state. Commenters discussed the impressive results, skin care routine, and the effects of estrogen on hair and skin.
