The European Society of Human Reproduction and Embryology (ESHRE), responsible for ensuring the interest and understanding of reproductive biology and medicine, has just proposed to deny the possibility of following an assisted reproduction treatment to those women who drink alcohol excessively and who do not want or are not able to moderate your consumption

In the same way, they indicate that there should be a more than justified reason to initiate a process of fertility in women with morbid obesity, and that the application of assisted reproduction should be accompanied by a commitment to change the habits of life, without which there is clear evidence of possible risks of harm to the fetus, or that the treatment presents a clearly negative cost-effectiveness balance.

Specifically, in relation to morbid obesity, the risk of gestational diabetes increases twice in overweight women and up to eight times more in women with morbid obesity; that of transmitting some type of congenital defect is 80% higher, while the chances of suffering cardiovascular anomalies would be three times higher than usual.

Tobacco, alcohol and infertility

Regarding tobacco, the chances of infertility in smokers are double that in nonsmokers, they even take longer to become pregnant and have more risk of abortion. Low birth weight and sudden infant death are other complications associated with tobacco use.

Alcohol consumption can have consequences such as miscarriage and low pregnancy rates, but the most serious are included within what is known as fetal alcohol spectrum disorders, ranging from physical and mental disabilities, to behavioral and learning problems .
