Lol! thats one way to put it or your are lucky enough to meet <1% people effected by stress. "In real life scenario of male and female procreation how accurate is the research on stress to determine the outcome of the gender" ChatGPT said: The relationship between stress and the sex of a baby (male or female) has been studied, but the science is still inconclusive and not highly predictive. Here’s a breakdown of what research shows: 1. The Hypothesis Some studies suggest that maternal stress around conception or early pregnancy might influence the likelihood of having a boy or girl. The proposed mechanism involves hormonal changes, such as: Cortisol (stress hormone): Higher cortisol levels might affect the uterine environment or sperm selection. Testosterone and other reproductive hormones: Stress might subtly alter hormone levels in ways that favor X- or Y-bearing sperm. 2. Evidence from Studies Population-level observations: Some large studies have found trends: Stressful events (natural disasters, economic crises) sometimes correlate with slightly lower male-to-female birth ratios. The effect is usually small, e.g., a few percentage points change in sex ratio. Animal studies: In mice, stress can influence sex ratios, supporting the biological plausibility. Human studies: Mixed results: Some studies suggest that chronic stress may slightly increase the chances of having a girl. Other studies find no significant effect. Confounding factors (nutrition, timing of intercourse, paternal factors) make results inconsistent. 3. LimitationsSelf- Effect size is tiny: Even if stress has an effect, it’s far from deterministic. You can’t reliably “predict” the baby’s sex based on stress levels. Difficult to measure stress: reported stress is subjective; hormonal markers fluctuate. Other stronger factors: Genetics, timing of ovulation, and random chance have a much bigger impact on the baby’s sex. ✅ Bottom line Research indicates a possible small influence of maternal stress on sex ratios, but it is not accurate or reliable enough to determine the outcome of a specific pregnancy. In real life, the odds of having a boy or girl remain roughly 50:50, and stress is just one of many tiny influences. Quote
