Remember Isaac Newton said – “Every action has an equal and opposite reaction“? Similarly, although birth control pills resist woman from becoming pregnant, which is a good thing from one point of view, at the same time from the other point of view, they have an equal and opposite reaction. A new study shows that birth control pills can halve the size of woman’s ovaries.
The study is led by Kathrine Birch Petersen from the Copenhagen University Hospital in Denmark. The was made upon 833 women between the ages of 19 and 46 who were attending the Fertility Assessment and Counselling Clinic in Copenhagen University Hospital.
However, the study shows that contraceptive pills can reduce the size of women’s ovaries by up to 50 percent, but it’s not as dangerous as it sounds. According to this research, women who take birth control pills have 29 to 52 percent lower ovary volume than women who are not on the pill, with the biggest reductions in women aged 19 to 30. That means, the contraceptive pills are able to mask a woman’s true fertility.
Birch Petersen said, “We expected to find an effect of the Pill. But during the project we were surprised at the quantified effect on ovarian reserve parameters as defined by anti-Müllerian hormone, antral follicle count and ovarian volume. Young women typically have well-developed and well-functioning ovaries, while women approaching their menopause have smaller ovaries with reduced egg production.”
But ladies, don’t panic! The good news is the contraceptive pill can improve your brain function and the ovaries appear to return to their normal size after the you stop taking the pill. The results were presented at the European Society of Human Reproduction and Embryology fertility conference (ESHRE conference) held in Munich last month.
