"CNN)Metformin use by men in the three-month period before they conceived a child was linked to a 40% higher risk of birth defects in the offspring, according to a study published Monday in the journal Annals of Internal Medicine.

Metformin is a first-line drug in the treatment of type 2 diabetes.
The research, which was done out of Denmark, used national registries to follow over 1 million births between 1997 and 2016 and compared the risk of major birth defects in babies based on paternal exposures to diabetes medications. The study observed only children who were born to women under 35 and men under 40. Babies born to women with diabetes were excluded.

The researchers considered men exposed to metformin if they filled a prescription for it in the three months before conception, which is how long it takes the fertilizing sperm to fully mature.

That's why you shouldn't have children past 40-45 years old. I was 27 when I became a father for the first time.
