Mostly True
Deep voiced men tend to have a lower concentration of sperm in their ejaculation than men with higher pitched voices.
The claim is supported by scientific research indicating that men with deeper voices tend to have lower sperm concentrations. Multiple studies suggest an evolutionary trade-off where deeper-voiced men, perceived as more masculine, may not have superior semen quality. However, these studies note that the differences are small and within functional fertility ranges. Thus, while the claim is generally supported, the effect is not substantial.

Deep voiced men tend to have a lower concentration of sperm in their ejaculation than men with higher pitched voices.
Scientific studies, including those from PLOS One and National Geographic, indicate that deep-voiced men have slightly lower sperm counts, although these counts are still within normal fertility levels. This claim is generally supported by the available evidence.
