Your weight might determine your fertility or infertility

Most people know that being overweight or obese boosts the danger of health problems like heart condition and diabetes. But many are oblivious that this can also diminish fertility and the prospect of having a healthy baby.

If you are trying to get pregnant, or intend to start trying, the closer you are to a normal weight, the higher your chance of conceiving (getting pregnant) and having a healthy baby.


Ideal weight for conception differs

The ideal weight for conception depends on how tall you are. Your body mass index (BMI) is a number based on your height and weight. The healthy BMI scale is between 18.5 to 24.9. Grown-ups with a BMI between 25 and 29 are regarded as overweight and a BMI over 30 shows obesity. You can find out what your BMI is using our BMI tool.


Overweight and fertility in women

Being an unhealthy weight can influence a woman’s fertility by causing:

  • hormonal imbalances
  • difficulties with ovulation (discharging an egg from the ovaries)
  • menstrual disorders.

It can also guide to difficulties with aided reproduction, such as in-vitro fertilization (IVF), ovulation induction, and intracytoplasmic sperm injection (ICSI).

Obesity is also linked with polycystic ovary syndrome (PCOS), a common reason of low fertility or infertility.


Overweight and fertility in men

Being very overweight or obese can also decrease a man’s fertility. This is possible due to a mixture of factors including hormone problems, difficulties with erection, and other health conditions linked to obesity. Erectile Dysfunction is prevalent in a lot of men. Some of the most effective drugs or medicines for erectile dysfunction are sildenafil citrate 100mg, sildenafil citrate tablets 100mg, sildenafil citrate 20 mg, Cenforce 100, Cenforce 200, Vidalista 20 mg, tadalafil 20mg, fildena 100, fildena 150, fildena 100 mg, i 10 pill, fildena ct 100, Viagra etc.


Weight loss in men who are overweight or obese can significantly improve total sperm count and quality. Attaining a healthier weight at least three months before conception can enhance the likelihood of conception. This is because sperm take about three months to mature and being within the healthy weight range during this point helps produce healthy sperm.


Overweight and pregnancy health

Getting closer to a healthy weight before conception raises the prospect of the baby being normal at birth and into adulthood.

Obesity and excess weight gain during pregnancy is also associated with a number of pregnancy complexities. These involve heightened risk of miscarriage, pre-eclampsia, high blood pressure, gestational diabetes, cesarean birth, and stillbirth.

Babies born to very overweight mothers have an enhanced risk of childhood and adult obesity and other long-term health predicaments.

A small weight loss can enhance fertility and pregnancy health

While the truths about obesity and reproductive outcomes can seem daunting, there is some good news. In women who are obese, even a little weight-loss advances fertility and pregnancy health. Also, some diet and lifestyle changes that curb excessive weight gain during pregnancy can enhance health results for both mother and baby.


Getting ready for pregnancy

If you are preparing to get pregnant, beginning a healthy eating and exercise plan now advances your chances of getting pregnant and having a healthy baby. By forming healthy changes to your diet and increasing your daily physical activity, you’ll be taking measures toward approaching a more healthy weight. This also essential when using IVF and other assisted reproductive technologies (ART).

Researches have found that obesity diminishes the speed of pregnancy and live births in women using ART, and increases the speed of miscarriage. But weight loss through diet, lifestyle, and other changes significantly better these outcomes.

Ask your specialist about any dietary supplements you may need, such as folic acid.


Suggestions for a healthier weight before pregnancy

Try these steps to a healthier weight:

  • Develop a healthy balanced diet drawn from the five food groups: vegetables and legumes; wholegrain bread and cereals; fruits; milk, yogurt, lean meat, cheese, and alternatives; poultry, eggs, fish, seeds, and nuts.
  • Cut back on discretional foods (including chips, fatty meats, biscuits, pastries, fast foods cakes, and confectionary) and only eat them in modest amounts.
  • Eat usual meals and curb unhealthy snacking.
  • Swap sweet drinks and alcohol for water.
  • Make half your plate vegetables at lunch and dinner.
  • Use a tinier plate to help decrease your portion sizes.
  • Get moving every day. Fit in normal physical activity like walking to the shops, taking the steps and training with your lover .
  • Spend less time relaxing by getting up regularly while using a computer or mobile device, and interchanging screen time for other activities.
  • Set a practical weight goal. It can help you feel motivated and productive. Striving for weight loss of half to at least one kilogram per week until you reach your objective weight may be a good goal.
  • Begin a healthy eating and exercise plan collectively with your partner to improve the chance of getting pregnant and having a healthy baby.

Making these lifestyle modifications will make a difference to your overall health, albeit they don’t cause weight loss. Begin making these adjustments before you start trying to conceive, and keep them up during your pregnancy and beyond.

Remember, if you’re already pregnant and want to shed weight it’s essential to talk to your doctor or a dietitian first before you start making any lifestyle modifications.

When it concerns diet, supplement a balanced eating plan that includes:

  • Vegetables and fruit – 7-8 portions per day
  • Calcium-rich foods – yogurt, milk or plant-based milk options
  • Whole and supplemented grains
  • Good quality protein – chicken, tofu, fish, legumes, eggs, etc.
  • Low mercury, high omega-3 fat fish twice every week (like salmon and rainbow trout)
  • Healthy fats from nuts, avocado, olive oil, etc.
  • Restricted caffeine (300 mg, or one or two coffees per day)
  • No alcohol (study is unclear on what proportion it takes to injure a developing baby, so it’s best to refrain completely)
  • Less ultra-processed foods like salty snacks, candy, fast food, and pastries
  • A fetal multivitamin with folic acid


No specific diets are associated with increased fertility. What’s more, beginning a really restrictive weight loss diet could actually fail. Experts caution against low-carb diets because they lack adequate folic acid, which is seen in enriched grain products like bread and pasta. Folic acid shields babies against rachischisis , and a new study revealed that ladies on low-carb diets are somewhat more likely to hold babies with this congenital anomaly.


Specialists agree that weight loss is never a quick solution. Losing weight is hard and, in some cases, it can add additional stress to the period of getting pregnant. Weight loss isn’t the sole answer, particularly if happening a diet doubles your tension and adds more self-blame. If you’re having difficulty conceiving, it’s tough to understand if weight loss is going to be the thing that helps. Plus, despite the best shots, a BMI within the “healthy range” isn't always attainable.


Instead of that train in weight, set practical goals like “eat another serving of vegetables daily” or “walk 20 minutes per day.” These small steps enhance your healthier lifestyle, and should encourage weight loss as another bonus.


The good news? Even without extreme weight loss, lifestyle modifications like eating well and exercising can have resolute effects on hormone levels. Even losing five percent of weight can help improve your chances of getting pregnant. And a healthy lifestyle is vital for both parents, so get your partner involved too.

Focus on these healthy habits, and don’t get too hung abreast of your actual weight. The number on the size doesn’t significantly exhibit your level of fitness or overall health.

Underweight and fertility

Being underweight (BMI below 18.5) can diminish a woman’s fertility by causing hormone imbalances that induce ovulation and therefore the chance of getting pregnant. Compared to women within the healthy weight range, underweight women are more prone to require quite a year to compel pregnancy.

If you're underweight and trying to conceive, a dietitian can work with you to modify your diet and support you placed on weight.

Overweight Men and Fertility

Compared with men of normal weight, overweight and obese men were more inclined to possess low sperm count, or not have any viable sperm.


A research checked out men's sperm count and body mass index (or BMI), which may be a measure of body fatness and is calculated using weight and height. Men with a BMI of actually 25 are regarded as overweight, and people with a BMI of quite 30 are regarded as obese.

Men who were healthy weighted, 24 percent had a low sperm count of .6 percent that had no viable sperm. Amongst the overweight men, 25.6 percent had a low sperm count and 4.7 percent had no viable sperm. Of the fellows who were obese, 32.4 percent had a low sperm count and 6.9 percent had no viable sperm.

Past studies regarding the connection between body mass index and sperm counts are confusing, with some finding no link.

The link could be described by the very fact that fat tissue can transform male hormones like testosterone into the feminine hormone estrogen.

There can also be other ways to elucidate the link. The hormone leptin, which is composed of fat cells, might damage sperm cells or the cells that produce them. Or it might be that elevated temperatures within the scrotum, thanks to more fat tissue, harm sperm cells.

More work is needed for researchers to know the effect of obesity on sperm cells, consistent with the study.

The analysis was limited, therein some previous studies of the link couldn't be combined in their analysis because data were missing, and therein sperm count is an imperfect measurement of fertility.


Obese or overweight men are more likely to suffer infertility thanks to poor sperm counts or lack of viable sperm.


There are numerous studies on the consequences of obesity on semen quality. generally, it is often compiled with the following points:

  • hypothalamic-pituitary-gonadal axis disruption
  • Destruction of Sertoli and Leydig cells
  • Insulin resistance and hyperinsulinemia
  • Impairment of DNA integrity with an increased level of oxidative stress
  • male erecticle dysfunction and sexuality during a reverse fashion in obese men.


However, few studies assessed the mechanism influencing low weight on male reproductive capacity. Limited by the amount of related studies, the corresponding mechanism remains unclear. Analogous to obese men, some researchers hypothesized that hormonal imbalance could also be involved in reduced semen quality in men with low BMI. Additionally, men with low BMI may have unhealthy lifestyles, also as slight malnutrition or subclinical adverse conditions, which could influence their reproductive health. Though there's still a lack of sufficient evidence and deeper studies are needed to point out the precise mechanism.


Given that obesity may be possibly harmful leading to male infertility, many researchers have begun to review the effect of weight loss on semen quality through activity interventions, dietary, or bariatric surgery. Some researchers imply that weight loss should be performed in obese men for seeking fertility treatment especially, since bariatric surgery may help infertile men induced by obesity to enhance their fertility. Studies have verified that low BMI may be a pernicious factor for male fertility.


Underweight Men and Fertility

Men with low BMI have limited parameters of semen, hinting that underweight could be a risk factor of male infertility. More study and research need to be conducted to detect the role of low BMI in male sterility.
