Background:
Danazol is a synthetic progestin with androgenic effects that is approved by the Food and Drug Administration for treatment of endometriosis, benign fibrocystic breast disease, and hereditary angioedema. In recent years, increasing numbers of transgender and nonbinary individuals seeking menstrual suppression have been offered danazol due to its potential to both induce amenorrhea and cause reversible androgenic side effects including pigmentation of vellus hairs and voice changes, which may be desirable in this population. There are currently no studies assessing use of danazol within the transgender population for menstrual suppression.
Objective:
This study's primary aim was to evaluate the use of danazol as a menstrual suppression agent in transgender patients.
Design:
This was a retrospective multisite cohort study of all individuals who had been on danazol at two tertiary care centers between 2000 and 2022.
Methods:
All patients prescribed danazol were identified using a search of the electronic medical records. For demographic purposes, comparisons were made between those who did and did not use danazol for the purpose of menstrual suppression. A detailed chart review was then performed to analyze the experiences of menstrual suppression in transgender and nonbinary patients.
Results:
Most transgender and nonbinary patients on danazol for menstrual suppression remained on it at their most recent follow-up visit, and many charts noted improvements in gender dysphoria, pelvic pain, dysmenorrhea, endometriosis, and heavy menstrual bleeding. Most transgender patients achieved amenorrhea.
Conclusion:
Danazol may be a reasonable option for menstrual suppression in transgender and nonbinary patients. Our findings show its potential to not only induce amenorrhea but cause desired androgenic symptoms and improve gender dysphoria, pelvic pain, dysmenorrhea, endometriosis, and heavy bleeding. While the androgenic effects of danazol are less desirable in cisgender populations, it is an attractive option for menstrual suppression in transgender and nonbinary patients.

01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
