Don’t believe me? Here’s the evidence & receipts 🔬🧾
😶🌫️Fragrance & phthalates
Phthalate exposure is associated with lower testosterone and impaired s***m parameters (count, motility, morphology).
PMIDs: 12882953, 16517630
🔥Heat exposure (tight underwear, laptops, hot baths)
Increased scrotal temperature negatively affects s***matogenesis, s***m count, and motility.
PMID: 17645557
🍺Alcohol intake
Alcohol consumption is associated with reduced testosterone and abnormal semen quality, even at moderate levels.
PMID: 25224766
🍟Poor diet & low micronutrient intake
Low intake of key nutrients (from whole foods) is associated with higher oxidative stress and s***m DNA damage.
PMIDs: 22416008, 24852678
🧬Oxidative stress & s***m DNA fragmentation
Oxidative stress is a major driver of s***m DNA damage, which can impact fertility and early embryonic development.
PMID: 24852678
💤Sleep deprivation & stress
Restricted sleep lowers testosterone levels, which directly influences s***m production.
PMID: 21317185
Theres no need to point fingers. It’s important that both partners receive the information that we are never given or provided with.
S***m take ~74-90 days to regenerate.
What you do now matters a few months from now.
Save this, share it with your partner, or come back to it when TTC feels overwhelming.
