Birth control prevents pregnancy by preventing the release of an egg from the ovaries. If an egg isn't released, it can't be fertilized. (No egg means no fertilization and no pregnancy.) So technically, birth control makes a woman keep her eggs.
The ones that break down along the way go through what's called "atresia." If you're taking the pill, you'll stop that mature egg from developing, but it doesn't stop the waves of atresia. So, it doesn't "save" your eggs or delay menopause.
Birth control doesn't affect fertility long-term. Some women think that long-term hormonal birth control use could “mess up” their fertility; others believe that because they're not ovulating while they're on birth control pills, patches, rings, or shots, their egg supply will be better than it would be, otherwise.
The hormones in the pill stop a woman's ovaries from releasing an egg (ovulating). They also make it difficult for sperm to reach an egg, or for an egg to implant itself in the lining of the womb.
So, whether you're on the pill, past menopause, or just trying to figure out where all those extra eggs we've all got but never use go, there's a pretty simple answer for a seemingly complex question: your body just absorbs them. Our bodies absorb cells all the time, actually.
A woman is born with all her eggs. Once she starts her periods, 1 egg develops and is released during each menstrual cycle.
Many of our patients wonder what happens when a woman doesn't ovulate. The answer is simple: the absence of ovulation or anovulation causes infertility, because without ovulation there can be no pregnancy.
In general, research suggests that for women who consistently have periods every 26 to 32 days, conception (getting pregnant) is most likely to occur during days 8 to 19.
For example, a woman at 30 often has around 100,000-150,000 eggs in reserve. By 35, that number is likely around 80,000. Late into the thirties, that number could be 25,000, 10,000, or fewer.
Women who are taking such contraception are more likely to present with lower-than-expected ovarian reserve. However, the majority of women willing to wait at least a few months should see an improvement in AFC and likely an improvement in oocyte yield.
If you consistently take an oral combination birth control pill, the hormones in the pill (progestin and estrogen) stop you from ovulating, which is what makes them effective birth control methods. However, if you are taking the progestin-only minipill, you may still experience ovulation.
How many eggs do women have in their 30s? There is no one right answer to this question, as certain factors – such as smoking or other personal factors – may mean a woman has fewer eggs than others. The average number of oocytes at the age of 30 would be around 72,000 (12% of maximum pre-birth levels).
Consumption of oral contraceptives for more than 2 years before pregnancy is associated with a higher risk of miscarriage.
Technically, yes you can—but because your natural hormone levels will be altered due to the synthetic hormones in your system, you won't be able to get an accurate result of your natural menstrual cycle hormone levels, including your follicle stimulating hormone (FSH), lutenising hormone (LH), or oestradiol (E2)..
How many eggs does a woman release each month? After a woman starts her menstrual cycle, one egg is ovulated and about 1,000 (immature) eggs are lost each month.
By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely.
The short answer is no. “Using hormonal birth control doesn't affect your ability to have a baby in the future,” says women's health specialist Miriam Cremer, MD.
More than 7 pills missed
If you've missed 8 or more pills straight after each other, you will not be protected against pregnancy. If you have had unprotected sex, you may need to do a pregnancy test or take emergency contraception. Contact a sexual health clinic, doctor, nurse or pharmacist urgently.
Did you know you can determine if an egg is fertile or not by looking at the germ spot? The germ spot is the white spot on the yolk. The non-fertile germ spot contains only the female's cells and looks like a solid white spot. In a fertile egg the germ spot contains both the female and male cells.
A menstrual cycle that's too long (35 days or more), too short (less than 21 days), irregular or absent can mean that you're not ovulating. There might be no other signs or symptoms.
Intro to assisted fertility. Any successful pregnancy is viable with just one egg. As an increasing number of women delay pregnancy until their 30s and 40s, getting pregnant is increasingly a sociotechnical process.
A vaginal ultrasound is the best way to accurately assess and count the number of antral—or resting—follicles in each ovary. These sacs contain immature eggs that may potentially develop in the future. Counting the number of follicles is called an antral follicle count (AFC), which is performed via an ultrasound.
