In today's episode we're diving into groundbreaking research on how ultra-processed food (UPF) impacts couples trying to conceive. Drawing from a major prospective cohort study, we explore the surprising discovery that a man's diet may be just as critical for fertility as a woman's. We discuss findings linking higher paternal UPF intake to reduced fertility and maternal consumption to slower embryonic growth and smaller yolk sac volume early in pregnancy. Join us as we unpack these sex-specific findings and what they mean for the future of preconception care.

Despite claims of anti-vaccine activists no different than groups that used to claim vaccines cause autism, COVID-19 vaccines do not impact fecundability—the probability of conception per menstrual cycle—in female or male partners who received the Pfizer-BioNTech, Moderna, or Johnson & Johnson vaccines. The prospective study instead indicates that COVID-19 infection among males may temporarily reduce fertility— an outcome that could be avoidable through vaccination.

Background Few studies have prospectively evaluated semen quality (using the most up-to-date clinically relevant definitions) and fecundability (the per-cycle probability of conception). Objective.....

Poverty, low educational level, and household income are associated with lower fecundability and subfertility, according to a study published online Sept. 19 in JAMA Network Open.

A groundbreaking new cohort study published in JAMA Network Open has unveiled compelling evidence that socio-economic factors, notably poverty and social disadvantage, exert a significant and measurable impact on human fertility. By rigorously analyzing data from both women and men, the researchers have elucidated how low educational attainment and reduced household income correlate with diminished fecundability—the month-to-month probability of conception—and an elevated risk of subfertility.
