Introduction to the Influence of Grandfathers on Menstruation

Over the last 55 years, young girls in the US have been getting their first periods earlier and earlier. Nowadays, the average age is roughly 12. Some girls may menstruate as early as 8, according to Healthline. Now, fresh research presented Sunday at the Endocrine Society’s annual meeting in San Francisco suggests the day of the blessed event could be influenced by an unlikely source: paw-paw.

The Role of Environmental Exposures

“Girls are starting puberty earlier than ever before, which can raise their risk for health problems later in life,” Xin Hu of Emory University’s Rollins School of Public Health in Atlanta said in a statement. “We wanted to explore why this might be happening by looking at how environmental exposures from grandparents can influence when girls get their first period.”

Researchers tapped into the Child Health and Development Studies (CHDS), which began in the 1960s, measuring thousands of small molecules in blood samples taken from 249 couples. Those chemical and metabolic profiles were then linked to puberty onset ages in their daughters (247 girls) and granddaughters (139 girls) — the latter born around 1990.

Findings on Puberty Onset Ages

While the median age at first period remained stable between grandmothers and mothers, it dropped a full year between generations in the granddaughters. The team found that specific chemicals — including phenoxyethanol, a preservative in personal-care products and foods — were associated with earlier puberty, especially when both parents had similar exposure levels.

The Influence of Paternal Exposure

Importantly, they found maternal and paternal exposures influenced timing, but it was the father’s contribution that stood out. “While we found that both the mother’s and father’s exposures were linked to when their daughters and granddaughters began puberty, the father’s influence was surprisingly strong,” Hu said. “Paternal exposure to environmental chemicals may play an unrecognized but critical role in shaping offspring endocrine health.”

Implications of the Study

The study is significant, as earlier puberty has been associated with an increased risk of Type 2 diabetes, obesity, certain cancers, and depression. “These findings highlight that prevention is possible if we identify mechanisms to protect future daughters and granddaughters, which cannot be effective if we do not consider the male line,” Hu said. These results are also important in light of concerns that chemicals in our environment — from microplastics to forever chemicals — are leading to long-term health risks for us, as well as our descendants.

Conclusion

In conclusion, the influence of a girl’s grandfather on when she gets her first period is a significant factor to consider. The study’s findings suggest that paternal exposure to environmental chemicals can play a critical role in shaping offspring endocrine health. This highlights the importance of considering the male line in the prevention of early puberty and related health risks.
