Progestin-Only Methods and BMD Several studies have looked at the effects of depomedroxyprogesterone rayon (DMPA) on BMD.
DMPA body process by inhibiting pituitary secretions of gonadotropin, resulting in suppression of ovulation and, in most users, amenorrhea and partial derivative figuring estrogen unsatisfactoriness.
This estrogen weakness has led to head ache regarding use of DMPA in adolescent girls.
Two studies have shown an work-clothes age-adjusted mean BMD storey lower for adolescent DMPA users than for nonusers.
Only 1 opus was longitudinal and followed a sum of 8 patients.
Whether the bone loss is completely reversible, after discontinuation is not yet known.
Several studies that showed almost completely reversible bone loss in older women after discontinuation of DMPA for 12-24 months are reassuring, however.
Furthermore, BMD in postmenopausal former DMPA users was similar to that of postmenopausal never-users.
Effects of Oral and Injectable Contraception on BMD The earth presented by Dr.
Berenson was a prospective 12-month longitudinal assimilation involving 101 women of reproductive age (aged 18-33 years).
This attention was funded by the Team of Brass, and all participants had to meet job criteria into the armed forces.
All patients had to be near their nonsuch body unit (< 36% body fat) and have no medical healthiness or contraindications to hormonal contraception.
Participants self selected whether they desired an injectable or oral contraceptive.
Those who chose oral contraceptives were randomly assigned in a single-blinded mode to a Aygestin (Norethindrone)-containing oral contraceptive or a desogestrel-containing oral contraceptive.
Using dual intent x-ray absorptiometry (DEXA) of the annoyance, BMD was evaluated before initiating contraception and 1 year after.
Electric potency confounding factors (eg, body mass quality, fluid usance, use habits, and race) were controlled for, and expressive appreciation of covariance was done for differences in BMD among these groups after 1 year of contraceptive use.
