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.
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 most cases, being overweight does not affect your ability to get pregnant. However, being obese (rather than overweight) can decrease your chances of getting pregnant. That's because weight can have an effect on your hormones and can prevent your ovaries from releasing an egg (ovulation).
You should aim for a BMI of between 20 and 25, as this will optimise your chances of conception. Even in these modern times, nature knows best. If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition.
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.
If you're overweight—which typically means you have a BMI of 25 or higher—your doctor may suggest losing weight to regulate ovulation and boost fertility. Even if you have PCOS, weight loss can help to improve the condition.
If you're overweight, doctors advise losing the extra pounds before you conceive, if possible. Going into your pregnancy overweight means you could put your own health and your baby's health at risk, and potentially set your child up for a lifetime of health issues.
Losing weight for fertility is different for every woman, but it can usually be achieved through a healthy diet and exercise plan. Exercising for roughly 30 minutes a day, eating balanced meals, and minimizing trans fats are a few common recommendations.
Losing weight while pregnant, other than in the early weeks, is not healthy for you or your baby. Dieting, trying to stay the same weight or losing weight in the second or third trimester of your pregnancy can deprive your baby of nutrients needed to grow and develop.
Other than age, causes such as endometriosis, ovarian cysts, some immunological disorders, obesity, chemotherapy, drug use, smoking, alcohol and caffeine consumption may also lead to decreased egg quality.
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.
The ideal BMI for getting pregnant, either naturally or through IVF, is between 19 and 25; typically, IVF can be less successful in women with a BMI over 30. High BMI can also be associated with anesthetic risks during egg collection, and pregnancy complications such as diabetes and high blood pressure.
It is possible to become pregnant during or after your period. This is because there can be irregularities in your menstrual cycle and ovulation days. As you get older, it becomes more difficult to pinpoint precisely when you are at your most fertile.
Fertility treatment
Some fertility drugs work by stimulating a woman's ovaries, which can sometimes cause them to release more than one egg. If sperm fertilizes both of these eggs, this can result in twins. In vitro fertilization (IVF) can also increase the chance of conceiving twins.
“Obesity can require special care, but a majority of women with B.M.I. over 30 don't have a complicated pregnancy and do have healthy babies.” Even when the risk for complications increases, the frequency of such events remains low.
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.
under 18.5kg/m2 – you are considered underweight and possibly malnourished. 18.5 to 24.9kg/m2 – you are within a healthy weight range for young and middle-aged adults. 25.0 to 29.9kg/m2 – you are considered overweight. over 30kg/m2 – you are considered obese.
This is weight in kilograms divided by the height in metres squared. In adults Overweight, or pre-obesity, is defined as a BMI of 25-29.9 kg/m², while a BMI ≥ 30 kg/m² defines obesity.
