Comparison of estradiol levels of oral contraceptives on mood

The results of a study comparing two different forms of triphasic oral contraceptive pills (OCP) on both mood and sexual interest were compared in a recent study which was published in the journal Contraception. Both pills had the same amount of progestin, but differing amounts of estradiol. The OCP with the lower amount of estradiol reducted free testosterone less and also resulted in a greater improvement in mood in a popluation of 60 university students.

"The lower EE (Ethinyl estradiol) pill reduced FT (free testosterone) less and was associated with greater improvement in premenstrual mood. A causal relation between these two effects is uncertain" (Greco et al, 2007).

New research links oral contraceptives to artery clogging plaque

As noted elsewhere on my site, birth control pills are one treatment option for women who suffer from the symptoms of PMS.

Data from a recent study was presented recently at the Amercian Heart Association. It's already well established that oral contraceptives or 'birth control pills' confer several risks including an increased risk of blod clots which can result in heart attacks or strokes--particularly in women who also smoke cigarettes.

Now, new data suggests that BCP's may also increase the risk of artery clogging plaques, even in women who no longer use the pill.
