Being underweight (BMI under 18.5) can reduce a woman's fertility by causing hormone imbalances that affect ovulation and the chance of getting pregnant. Compared to women in the healthy weight range, women who are underweight are more likely to take more than a year to get pregnant.
If you are underweight (your BMI is 18.5 or less), you may have problems getting pregnant. Being underweight can cause your body to stop making estrogen. This can cause irregular menstrual cycles. You may stop ovulating and getting your period.
In fact, obesity is the cause of fertility struggles in six percent of women who have never been pregnant before, says the American Society for Reproductive Medicine (ASRM). Obesity affects infertility by changing the way a woman's body stores sex hormones.
The ideal BMI for getting pregnant is between 18.5 and 24.9. This is known as the healthy range. If you have a high BMI, bringing it closer to the healthy range before trying for a baby will help you get pregnant as well as improving the health of your future pregnancy and child.
Being overweight, obese or underweight can affect a woman's fertility. Obesity can lower fertility in men. You have a greater chance of getting pregnant and having a healthy baby if you are close to a healthy weight. A small weight loss can improve fertility and pregnancy health.
Men whose AGD is shorter than the median length -- around 2 inches -- have seven times the chance of being sub-fertile as those with a longer AGD, a study finds. When it comes to male fertility, it turns out that size does matter.
If your menstrual cycle lasts 28 days and your period arrives like clockwork, it's likely that you'll ovulate on day 14. That's halfway through your cycle. Your fertile window begins on day 10. You're more likely to get pregnant if you have sex at least every other day between days 10 and 14 of a 28-day cycle.
Women with a body mass index (BMI) above 27 are three times more likely than women in the normal weight range to be unable to conceive because they don't ovulate. Women who are overweight or obese are much less likely to conceive.
Affects ovulation, hormones & sex drive
This can be reversed by weight loss. A 5 to 7 percent decrease in body weight, or about 10 to 20 pounds, by an obese woman will increase her chances of getting pregnant. It takes longer for obese women to become pregnant, which can be a mentally debilitating factor.
Women with a BMI of less than 18.5 are considered underweight. The average woman's height is 5 feet, 4 inches. If you weigh 107 pounds or less at this height, you are considered underweight with a BMI of 18.4. A healthy weight range for that woman would be 108 to 145 pounds.

Obese and overweight women tend to have lower estrogen levels than those with a normal BMI. As estrogen is responsible for triggering ovulation, a lack of it may lead to infertility. Insulin resistance, another obesity-linked condition, can also disrupt ovulation.
If you don't get pregnant after one year of trying, talk to your doctor. If you're 35 years old or older, you should see your doctor after six months of trying without success to get pregnant. If you have a possible sign of infertility before the one-year mark, your doctor can run some basic fertility tests.

There's a very good chance if you are experiencing a regular monthly period, you are fertile. While it is true that women have a finite number of eggs, lack of conception is predominately due to other causes. From the moment a girl is born, she typically has between one and two million eggs in her ovaries.
Your basal body temperature falls slightly, then rises again. Your cervical mucus becomes clearer and thinner with a more slippery consistency similar to that of egg whites. Your cervix softens and opens up. You may feel a slight twinge of pain or mild cramps in your lower abdomen.
