Caffeine is associated with an increase in male fertility

A growing body of research has shown that male fertility has declined significantly over the past four decades in Western countries in North America, New Zealand, Australia and Europe. According to a study, last year in the Update of human reproduction, the collective sperm count among men in western countries has declined by more than 50 percent.

Organizations like that Eunice Kennedy Shriver National Institute for Child Health and Human Development (NICHD) work to better understand the processes underlying human reproduction to alleviate infertility.

A recent NICHD study found that men who drink two or more cups of caffeinated coffee or tea every day are more likely to successfully impregnate their partners. The finding could be attributed to the effects of caffeine on two chemicals, adenosine triphosphate (ATP) and guanosine triphosphate (GTP), which are involved in energy transfer and metabolic reactions.

Professor Sheena Lewis of Queens University Belfast explains how consuming tea or coffee can affect ATP and GTP in terms of the reproductive process: "Caffeine prevents them from collapsing, giving the sperm more energy to swim faster or longer."

NICHD research also found that women who drink alcohol every other day are 26 percent less likely to become pregnant and that severe depression and an antidepressant have negative effects on both male and female fertility.

"A study of major depression in couples with infertility showed that currently active major depression in infertile men can reduce the chances of pregnancy, and the use of non-selective serotonin reuptake inhibitors in infertile women could be associated with first trimester pregnancy loss . "
