71 days. Not only women, but also men should clean their bodies before conceiving a child<

“Of course, this does not apply to cases where women enter another state by accident or unintentionally. However, couples planning a family should take various precautions. Quit smoking, and that includes, let's say, marijuana, quit drinking alcohol and start eating healthy," he says.

We automatically expect such recommendations from women as carriers of the fetus, but men should proceed in the same way. "It's very important for women because they are born with eggs that age from birth. And they take everything pathological with them, they record what the woman ate, smoked, drank. This can appear there as a metabolite, and therefore the body needs to be cleaned. At least three months in advance," recommends the doctor.

"It's also important for men," continues Dana Preslová, "even though the sperm has a completely different cycle. Each sperm takes 71 days to develop. And this is the key time for the male sex cell to be healthy. If it has any pathologies in it, the embryo that will be created thanks to this sperm can be damaged. So even men need to live healthily for at least three months beforehand."

Another circumstance that can affect conception is the body weight of the parents. Obesity is most often an obstacle. But even a very low weight can prevent a woman from becoming pregnant. "When anorexic women get below a certain weight, they lose their periods, and with that, of course, the ability to conceive and give birth to a healthy child," says the gynecologist.

It also warns against overly demanding and vigorous sports training. "Recreational sports with a moderate load, such as light running, calanetics, pilates, yoga and the like, are certainly possible for an otherwise healthy woman. But top-level sports or circuit training in the gym definitely not," he reminds.
