Scientists decipher the reason for the decline in the probability of conception caused by coffee

According to foreign media reports, many previous studies have confirmed that drinking too much coffee will affect women's fertility. One of the studies involving 9000 Dutch women found that drinking more than four cups of coffee a day reduced the chances of conception by about 1/4. However, the mechanism of this situation has not been cracked for a long time.

In the latest study, scientists conducted experiments on mice and found that caffeine can cause specific guiding cells in the inner wall of the fallopian tube to lose their vitality and inhibit the contraction of the fallopian tube, thus affecting the smooth entry of eggs into the uterus. Thus affecting the entry of eggs into the uterus. Professor Sean Ward, of the University of Nevada, who led the study, said: "the findings will explain long-standing doubts about why drinking caffeinated drinks reduces a woman's chances of becoming pregnant."

Drinking more than four cups of coffee a day will reduce the chances of conception by about 1/4.

Professor Shawn said this could provide an explanation for why women consume too much caffeine and tend to take longer to get pregnant than other women who consume less caffeinated drinks. It is understood that the findings have been published in the British Journal of Pharmacology (British Journal of Pharmacology).

The researchers say the research may help people learn more about how fallopian tubes work, help doctors better treat pelvic inflammation and some sexually transmitted diseases, and improve their understanding of ectopic pregnancy.
