The medroxyprogesterone (Depo-Provera) injection has a black box warning due to:
decreased bone density
Testosterone gel negatives
expensive, can touch clothes
Estrogen
has positive effects on bone mass, increases serum triglycerides, and improves ratio of high-density lipoprotein to low-density lipoprotein. stimulates coagulation and fibrinolytic pathways.
transdermal testosterone
more common than gel, oral doesnt work well
menopause
no menses for 12 months
depot provera
one dose every 12 weeks
testosterone
primary male androgen
Luteal phase:
progesterone prevents new follicle development as well as differentiation of the endometrium
symptoms that are helped with menopause and HRT
reduce vasomotor symptoms, reduce vaginal atrophy, reduce osteoporosis,
Gonadotropin-releasing hormone (GnRH) pulses
regulate follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn, regulate the secretion of estrogen and progesterone from the ovary.

implanon
up to threee years, rod

•Increases bone density •Results in normal skin and blood vessel structure •Affects lipid levels •Reduces bowel motility •Enhances coagulability of blood •Causes edema because of its action on the renin-angiotension system •Maintains stability of the thermoregulatory center

•Low-dose estrogen (0.3 to 0.625 mg daily) alleviates symptoms. •Vaginal application of estrogen (ring or cream form) can improve symptoms in as little as 2 weeks. •Topical application is preferred because of lower overall estrogen dose and no systemic effect.
