Men can now relax as study shows being obese doesn’t slow a man’s sperm

Being overweight does not slow a man’s sperm, research suggests.

A new study contradicts the theory that having a high BMI reduces male fertility.

After analysing more than 200 men with healthy, overweight and obese BMIs over 10 months, the Nigerian scientists found no significant difference in their sperms’ speed, size or shape.

This comes just weeks after Bath and North East Somerset clinical commissioning group announced they will be denying IVF to women if they have a male partner with a BMI over 30, which is classified as obese.

Official guidance from the National Institute for Health and Care Excellence (NICE) also states that men with a BMI higher than 30 are less likely to father children.

The researchers, from the University of Benin, analysed 206 healthy men whose BMIs ranged from normal, at 18.5-to-25, to obese.

The men, who were aged between 20 and 40, submitted sperm samples that were assessed in a lab for their count, motility and shape, as well as any abnormalities.

They were followed over 10 months.

According to the researchers, the results, published in the International Journal of Reproductive Biomedicine, suggest that ‘elevated BMI does not significantly influence semen quality’.

Lead researcher Dr James Osaikhuwuomwan said: “Comparison of semen parameters of the study population with BMI, showed that there was no statistically significant difference in the semen parameters (sperm count, motility and morphology) of the study population with normal and elevated BMI.

“Also, a comparison of semen defects amongst BMI groups of study population noted that there was no statistically significant difference in the semen abnormalities between men with normal and elevated BMI.’

Despite no link being found between a man’s weight and his fertility, Dr Osaikhuwuomwan stills recommends males maintain a healthy size to benefit their overall well-being.

He said: ‘There is no controversy that overweight and obesity have become major health concerns worldwide and the benefits of weight control cannot be over emphasised.

“Male partners of infertile couples with elevated BMI seeking treatment can be reassured that their BMI may not adversely affect their semen quality as well as their quest for conception but overall obesity is discouraged for healthy living.”

Speaking of the findings, Hana Visnova, medical director of the fertility clinic IVF Cube, Prague, who was not involved in the study, said: ‘There’s actually very little evidence to link obesity with sperm quality in men and this warrants further study.

“There are, though, other things to consider when it comes to libido and sex drive.

“A high level of obesity indirectly influences sexual appetite. Obese patients may have high blood presssure and other health issues that may cause erectile dysfunction and libido impairment.”

Dr Allan Pacey, a fertility expert at the University of Sheffield, also recently argued there is ‘no consensus’ on evidence suggesting male infertility is driven by a man’s BMI.

These notions contradict a study released in July last year that suggested sperm counts in the West have declined by 60 per cent in the last 40 years, with the researchers blaming obesity, as well as stress and smoking.

Further research released last September by Indian scientists also suggested a link between obesity and men having a lower sperm quality.

Lead scientists Dr Gottumukkala Ramaraju said: “The health and reproductive performance of spermatozoa in obese men are more likely to be compromised both qualitatively and quantitatively.”

Kenyan women are amongst the most obese in Africa

Kenyan women are among the most obese in Africa, a new report suggests.

Among the 36 African countries sampled, Kenyan women ranked ninth.

The report, Nutrition in the WHO African Region, was released last week by the World Health Organization.

It shows the most unhealthy weight gain is found among the Swazi and Lesotho women.

South Africa is not listed — although it is known to have the worst cases of obesity.

The least obese women are found in Ethiopia, Madagascar and Burundi —  nutritionists feel this largely has to do with malnutrition, rather than healthy living.

“Overweight or obesity in mothers increases the risk in their offspring of high birth weight and subsequent childhood overweight,” the report says.

According to the Ministry of Health, average overweight rate among Kenyan women is 33 per cent, which is attributed to poor nutrition.

Women in Nairobi and Kirinyaga counties are the most overweight.

Head of Nutrition and Dietics Unit Gladys Mugambi said about 47 per cent of women in these two counties are either obese or overweight. This is among the highest levels in Africa.

“Cases of overweight expose one to diseases like high blood pressure and diabetes, which are very expensive for the county and the patient to treat,” Mugambi said last week during a meeting with health workers on capacity development for nutrition.

The WHO report says the percentage of women classified as overweight — including obesity — in Africa averages 23.8 per cent.

The range is from 5.7 per cent in Ethiopia to 50.6 per cent in Swaziland.

WHO said data for this indicator are available for 36 countries — as found in surveys dated between 2000 and 2015.

In all, 12 countries have a prevalence rate of more than 30 per cent, while Gabon, Ghana and Lesotho have more than 40 per cent.

“We are getting wealthier. Unfortunately, we are not eating correctly and we have a big problem with physical activity. I wish Kenyans were more active and could eat better,” Deputy director of Medical Services Peter Cherutich said last Friday.

“We have a long way to go in improving our nutritional status and reducing our consumption of sugar, alcohol and other unhealthy substances.”

Lead author of the Report, Dr Adelheid Onyango, who is WHO Africa’s adviser on nutrition, says the obesity epidemic affects all age groups.
