To maximize your chances of conceiving, it is best to have sex in the morning during certain months of the year. Find out the perfect hour and month.
At a time when more and more couples are struggling with infertility problems, researchers wanted to know when sperm was best able to fertilize eggs. To do this, they analyzed 12,245 semen samples from 7,068 men, aged 25 to 40 and undergoing infertility treatment with their partner. The samples were taken at the Zurich hospital between 1994 and 2015. Were scrutinized: the number of spermatozoa, their mobility and their morphology.
“The semen samples taken early in the morning, before 7:30 am, are those which contained the most sperm of normal morphology”, indicates the essay, published in Chronobiology International. “In addition, a significant increase in the total number of spermatozoa was observed in the spring; significant decreases in this same variable were noted in the summer”, we can still read. More specifically, March, April and May are the months when the quality of sperm is the best. During the experiment, however, the motility of the sperm did not change depending on the hour or month.
“The quality of human sperm varies according to circadian and circannual rhythms”
Having sex early in the morning can therefore improve natural fertility, just as collecting semen before 7:30 a.m. can increase the chances of successful assisted reproduction. Professor Brigitte Leeners, lead author of the study, also clarified that “the quality of human sperm varies according to circadian and circannual rhythms”. Dr Hana Visnova, who runs the IVF Cube clinic in Prague, warns, however, that “men with low sperm count should not be content with morning sex and will certainly always need medical help to make their dreams come true. to found a family “.
According to the latest Weekly Epidemiological Bulletin from the Public Health France agency, male reproductive health in France is undergoing an overall deterioration, a priori favored by early exposure to endocrine disruptors. Between 1989 and 2005, a significant and continuous 32.2% drop in sperm concentration was observed. For a 35-year-old man, the average concentration fell from 73.6 million sperm / ml in 1989 to 49.9 million / ml in 2005, a decrease of about 1.9%, (1.4 million sperm) per year.
Half a million babies are born each year from IVF and ICSI
For testicular cancer, the mean crude incidence rate in the study period was 6.5 / 100,000, with an increase in cases of 1.52% per year. There is a great heterogeneity of the disease at the national level, with high incidences in the far west and the far east and generally lower incidences in the southern half compared to the northern half of France. Equally worrying is the number of birth defects. The average incidence rate of cryptorchidism in boys under 7 years of age during the study period was 2.57 / 1000, with an increase in cases of 2.64% per year.
As a result, forty years after the birth of Louise Brown, the world’s first “test-tube baby”, the European Society of Human Reproduction and Embryology (ESHRE) now reports that the total number of babies born as a result of ‘In vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is more than 8 million in Europe. We think that over half a million babies are born each year from IVF and ICSI as a result of more than 2 million treatments carried out. Before going through that, men can also simply improve the quality of their semen by eating nuts, as has been shown. a recent study, or favor morning sex.
