The weight gain caused by the pandemic threatens fertility

A review of Amnios in Vitro Project studies analyzes the impact of overweight and obesity on reproductive capacity. The Spaniards have fattened an average of 5.7 kilos due to changes in habits developed in the pandemic

Male and female fertility is threatened by the most accumulated kilos during the covid-19 pandemic. This ensures a review of studies by the assisted reproduction clinic Amnios In Vitro Project as part of World Obesity Day. “The overweight is directly related to low egg and sperm quality. Due to the confinement, lack of physical activity and disorder in food intakes, the Spaniards have increased weight in the last year. These extra kilos can damage the search for a pregnancy and even be very harmful during pregnancy,” explains Dr. Victoria Verdú, medical director of the Madrid clinic.

The Spanish have fattened an average of 5.7 kilos since the beginning of the pandemic due to the change of habits developed in these months. Spain is the European country in which more people (38% of respondents) recognize that they have gained weight. It's data from a survey carried out by Ipsos in 30 countries. “The change of habits during the pandemic has made the Spaniards take a few kilos. The consumption of ultra-processed products, snacks, sugary drinks has increased, and also, in many cases, physical activity is not performed,” says this gynaecologist.

An investigation published in International journal of endocrinology and metabolism ensures that female and male obesity and overweight increases the risk of subfertility and infertility. In the case of women, it affects ovarian and extraovary factors. “Women with overweight or obesity take longer to conceive and have a lower fertility rate. In addition, they need a higher requirement of gonadotropins and have a higher rate of miscarriages compared to those with a normal weight,” explains Dr. Verdu. bricoducha.es

In the case of male fertility, extra kilos can also cause subfertility. “The hypothalamus-hypophysis-gonated axis (HPG) can be altered, the testicular temperature increases, the physical and molecular structure of the sperm is modified, the quality of the sperm decreases, and it can cause erectile dysfunction due to the peripheral vascular disease,” says this specialist.

Low weight also reduces fertility
On the other hand, low weight can also make it difficult to find a pregnancy. A Chinese research published in Fertility and Sterility in which more than two million couples participated reveals that couples in which the two have overweight or underweight, have a 10% less chance of success in getting the pregnancy than those with a normal BMI (body mass index). “The low weight affects hormonal production and metabolism. It can therefore cause alterations in the menstrual cycle of women, with irregular menstruations; absence of the same or alterations in the endometrial, which would prevent implantation in the event of pregnancy. In the male, the low weight causes less concentration and mobility of the sperm”, says Dr. Verdu.

In addition, this gynaecologist warns about the impact of overweight or obesity once the gestation is achieved. “Numerous studies warn of the consequences of pregnancy as a higher risk of miscarriage, hypertension, or gestational diabetes, preeclampsia, or premature birth,” explains Dr. Verdu. Therefore, from Amnios In Vitro Project, a message of control of lifestyle-related factors is insisted to improve fertility. “A good diet and avoiding toxic habits such as tobacco or alcohol are essential for improving health and reproductive capacity,” concludes this expert on assisted reproduction.
