Touted as "the" option for preventing pregnancy and "normalizing" painful and difficult menstrual cycles - most women I see in my office don't seem to fully understand that shutting down your ovaries is the implication of using birth control pills. Moreover, if you thought about birth control pills in this way what do you think the response would be from roughly 60-70% of the Canadian female population who use them?
What if you asked a man to take something that stopped him from producing sperm, what do you think he'd say? ... and therein lies my point.
Let's talk about how oral contraceptives work...
In the last two weeks alone, I have had several women look at me with shocked expressions when I explain to them how birth control pills work. They have ALL said - they just wish they had known, as they may have made different decisions regarding long-term contraception methods. In fact, when I was in naturopathic medical school our whole classroom of naturopathic med students responded the same way, men included.
Please understand, as a naturopathic physician, I am not categorically "anti-birth control pill", as the benefits of taking it are obvious and useful for many women. I am however, "pro-informed choice", and this over-looked aspect of birth control education appears to game-changer for enough of my patients, I thought you might find it useful.
The answer depends on the particular product, but generally oral contraceptives fall into 2 groups:
The pill is believed to inhibit ovulation via means of a "trick" played on the ovaries and pituitary. To understand this, you need a simplified crash course in ovarian hormone cycling... bear with me...
Phew... now, back to the birth control.
So, with birth control pills providing post-ovulation levels of the ovarian hormones (estrogen and progesterone) to your body without the work of your ovaries, your pituitary is kind of "in the dark" - assuming everything is going "according to plan" and it is just humming along doing it's thing. If your ovaries aren't producing the hormones because the pills are, they aren't doing the work (i.e. no egg recruitment). The trick is, by shifting hormone levels to make it appear like you've ovulated, the pituitary doesn't provide the LH/FSH surges required to release an egg. This is how we believe the birth control works to prohibit ovulation. Effectively, your ovaries aren't doing much of anything... At best, they push the odd hormone around, but mostly are waiting for hormonal instructions from the pituitary (FSH/LH) that never come.
Now imagine, this has been going on for 5-10 years or more without a break! It's surprising how many people do this to their ovaries, and then when they decide to become pregnant are baffled as to why they are having trouble with it.
The short answer to what that means for your fertility, is that we don't know. Whether you plan on having children or not, it seems counter-intuitive to have the function of any body part suppressed for that length of time. What risk implications does this have for your health in the long term? Menopausally or as a senior? We don't know that either. Not really...
As a physician, I am concerned that our young women are being prescribed birth control pills routinely as a method of "regulating" painful or difficult menstrual cycles. When in fact, their young pubescent ovaries are simply being "turned off" before they even get the hang of things. Young women seem to believe that their bodily menstrual cycles are "regulating" with birth control use, which is the exact opposite of what is happening. 10 years later for the same woman now wanting a child, finally coming off of birth control pills, this means that their ovarian function (and so, fertility) may be compromised.
The consolation prize is, that many fertility treatments (including natural ones) out there are helpful in improving ovarian function. But, wouldn't you consider condoms more seriously if you understood that it would mean healthy ovaries and avoiding the need for expensive fertility treatments and procedures in the future?
