Recent research is drawing unexpected parallels between the reproductive lives of seals and the challenges facing human fertility, sparking fresh conversations about the hidden environmental factors impacting reproductive health worldwide. As reported in a feature by Oceanographic Magazine, scientists are turning their attention to seals — charismatic marine mammals that live far from hospitals and clinics — in hopes of unraveling why fertility rates are declining across species, including humans (Oceanographic Magazine).

Secondary infertility, a condition where couples struggle to conceive after successfully having had at least one child, is becoming an increasing concern among families worldwide, including here in Thailand. Recent reports and new research highlight not only a steady rise in cases but also the typically overlooked emotional turmoil experienced by affected parents—an issue that has resonated with many Thai families amid shifting demographics and social expectations.

The significance of this trend is well-captured by the candid story of Charlotte Bennett, as reported in The Times. Bennett, already a mother, described the “horrendous” guilt of being unable to give her six-year-old son a sibling, despite years of effort. For many parents, secondary infertility brings an unexpected and deeply personal form of distress, often complicated by cultural expectations and misconceptions that once a couple has had one child, further pregnancies should be easy and natural (The Times).

As more Thai couples and individuals consider starting families later in life, questions about fertility—especially egg quality—are on the rise. Popular wisdom and online advice often tout lifestyle tweaks, diets, or supplements as the magic keys to improving fertility. But does the science back up these claims? According to a comprehensive review of recent research, including a widely cited article from SELF and several new studies in 2024, the answer is nuanced. While age remains the single most influential factor, certain everyday habits may indeed nudge the odds—though not as much as many would hope.
