Fertility Studies
A "CAP-SCORE" has been shown to predict the probability of pregnancy. (7)
Observational 2017 study showed parabens correlated with worsening sperm shape, motility and decreased testosterone. (1)
A 2017 meta-analysis showed 5-PDE likely do not harm fertility and they might even help. (2)
Acetaminophen and aspirin may negatively impact fertility parameters. (3,4)
Eating nuts may help sperm parameters. (5)
Wearing boxers may provide better sperm parameters than tighter underwear. (6)
