Description
Fırat Şahin and co-authors ask whether a father's age sours embryo results when mothers have polycystic ovary syndrome, in a 2026 study. The couples all used direct sperm injection, and the women were 35 or younger. Records of 192 cycles split the men into three age bands, the oldest thin at nineteen. Lab marks covered egg counts, ripe eggs, fertilized pairs, and frozen stock, plus an early hormone test of pregnancy.
One gap showed on paper, in fertilization rate across the bands, yet it faded once pairs were compared head to head with strict correction. Pregnancy test rates sat near half in each band, with no firm split. Tuned models that weighed the mother's age, body size, smoking, and sperm traits found no lone effect of the father's years. The authors urge care: the old-father group was small, and later birth outcomes went unmeasured.
