Wat doet de anticonceptiepil met je hersenen?

What Are Birth Control Pills Doing to Your Brain?

The majority of you are taking birth control pills to control your PCOS symptoms.
Besides providing you with immediate relief, maybe you think these pills are completely harmless and you can continue to take them with impunity for as long as you want.
But do you ever wonder those artificial hormones you're taking every day are doing to your body besides giving you a "monthly bleed" and a sense of normalcy?
Take your brain for example. Do you think they might be affecting your brain in some way?
I was doing some research on vitex extract when I stumbled across some studies regarding oral contraceptives and brain function. I'll share a few of them here. I think this is important.
1) University Hospital Essen at the University Duisburg-Essen in Germany studied 94 women ranging in age from 18-80. They took a magnetic resonance image (MRI) of each woman's pituitary gland, which is located in the brain. The pituitary is one of the two "master glands" that governs everything going on in your body.
As expected, the researchers verified that the pituitary gland shrinks as women get older. But they found out something else.
They also discovered that the women who had taken birth control pills also had smaller pituitary glands.
Folks, I don't know what happens to you when your pituitary gland shrinks. But it can't be good, can it?
2) Are you taking one of those newer "third-generation" "anti-androgen" birth control pills such as Yasmim? These birth control pills contain a synthetic progesterone mimic called "drospirenone".
These anti-androgen birth control pills are often prescribed to you because women with PCOS tend to have androgen levels that are too high. Androgens are male hormones such as testosterone. The excessively high levels of androgens is one of the main factors causing polycystic ovary syndrome problems.
If you're taking one of these newer birth control pills such as Yasmin, this study from the University of Wisconsin will interest you. They gave a mental task to 115 women who were taking various oral contraceptives.
Women who were using the older types of birth control pills that had an androgenic effect performed the mental task better than anyone else, including women who were not using birth control pills at all.
On the other hand, Yasmin users not only performed more poorly on the mental task in comparison to older generation pill users, but they performed significantly worse than women who were not on birth control at all.
The authors concluded: "visuospatial performance is hindered with the introduction of anti-androgenic preparations."
3) Birth control pills containing drospirenone have another disturbing attribute, according to a study published by the Universitaire du Sart-Tilman in Belgium.
Thirty-two young women taking birth control pills containing ethinylestradiol (synthetic estrogen) and drospirenone (synthetic progesterone) were compared to 30 young women not taking birth control pills.
They found that the birth control users had significantly higher levels of "lipid peroxides" than the women not using the pill.
Lipid peroxides are essentially rancid fats that act like loose cannons in your body, blowing up whatever they touch and causing a chain reaction of cell damage.
4) Some of you may be using another synthetic progesterone mimic called "medroxyprogesterone acetate". What effect might this imitation progesterone have on your brain?
The University of Southern California performed an experiment on female rats. They exposed the rats to medroxyprogesterone, to an estrogen, or to a combination of both.
They found that medroxyprogesterone impaired brain cell function, and caused an increase in lipid peroxides, which in turn leads to cell damage.
Interestingly, they noted that medroxyprogesterone has a different effect in the brain than does the "natural progesterone" created by the body.
Well, what do we do now? Just carry on and ignore this information?
I can't tell you what to do. But as a minimum, you can maintain an awareness that you are introducing some very powerful, unnatural substances into your body when you take a birth control pill. When you do so, there will be unintended consequences.
Personally, I cannot in good conscience recommend birth control pills as the preferred way to treat PCOS.
The foundation for long-term effective management of PCOS without the risk of side effects is to improve the quality of your diet, reduce chronic stress, exercise consistently, take selected nutritional supplements as needed, and live a healthier lifestyle. To this you can add pharmaceuticals if required.
