does ph affect gender of baby

Introduction

The question of whether pH affects the gender of a baby has been a topic of interest in reproductive biology. Various studies have explored the potential influence of vaginal and seminal fluid pH on the sex ratio of offspring, with mixed results.

Key Insights

Influence of Vaginal pH on Fetal Sex:
- Studies suggest that an alkaline vaginal pH is associated with a higher likelihood of male offspring, while an acidic vaginal pH is associated with a higher likelihood of female offspring .
Seminal Fluid pH and Sex Ratio:
- Research on rabbits indicates that altering the pH of seminal fluid does not significantly affect the sex ratio of offspring. The sex ratios remained close to the expected 50% regardless of whether the semen was acidic, neutral, or alkaline.
Sperm Motility and pH:
- Sperm motility is affected by pH levels, with acidic conditions being more detrimental than alkaline conditions. However, this does not translate into a significant effect on the sex ratio of offspring.

Conclusion

The research indicates that while vaginal pH may have some influence on the sex of the offspring, with alkaline conditions favoring male offspring and acidic conditions favoring female offspring, the pH of seminal fluid does not appear to have a significant impact on the sex ratio. Overall, the evidence suggests that vaginal pH could be a natural method to influence fetal sex, but seminal fluid pH is unlikely to be a determining factor.

A 7-year experience of genetic males with severe phallic inadequacy assigned female.

Genetic males with severe phallic inadequacy can have functional psychosocial development, with those reared female having a realistic likelihood of recognizing male sexual identity and converting to male.

The effects of altering the pH of seminal fluid on the sex ratio of rabbit offspring.

Altering the pH of seminal fluid does not significantly affect the sex ratio of rabbit offspring, but may reduce sperm motility.

Effect of vaginal pH in preconceptional fetal sex determination

Vaginal pH can be used as a natural method to determine fetal sex, with significant associations between fetal male sex and alkaline pH and fetal female sex and acidic pH.

Does gender of the fetus have any relation with fetal heart monitoring during the first and second stage of labor?

Male fetal gender is associated with higher rates of abnormal fetal heart monitoring during labor, lower Apgar scores, and lower pH values compared to female fetuses.

Determining the sex of baby rabbits by ascertaining the pH of the vagina of the mother before mating.

Vaginal pH before mating in New Zealand white rabbits influences the sex ratio of offspring, with pH levels between 6.34 and 7.34 resulting in more female offspring and above 7.55 resulting in more male offspring.

Exposure to Phthalates and Phenols during Pregnancy and Offspring Size at Birth

Prenatal exposure to 2,5-DCP and BP3 is inversely associated with male birth weight, while BP3 is positively associated with weight and head circumference at birth.

Assignment of sex in neonates with ambiguous genitalia.

Sex assignment in newborns with ambiguous genitalia should shift from current criteria based on phallus adequacy and potential fertility to a broader understanding of gender identity and psychosocial development outcomes.

Gender aspects of preterm birth

Boys are more likely to be delivered prematurely, have higher neonatal deaths, and have better outcomes than girls, with males facing greater respiratory distress syndrome risks and pulmonary hypoplasia.
