What is Syntest DS (esterified estrogens and methyltestosterone)?

Esterified estrogens are female sex hormones necessary for many processes in the body.

Methyltestosterone is a man-made form of testosterone, a naturally occurring sex hormone that is produced in a man's testicles. Small amounts of testosterone are also produced in a woman's ovaries and adrenal system.

The combination of esterified estrogens and methyltestosterone is used to treat symptoms of menopause such as hot flashes, and vaginal dryness, burning, and irritation.
