Study negates voice changing ovulation theory
Recent studies have suggested that a woman's voice can help men detect whether or not she is ovulating. However, a new study is seemingly negates that theory, saying that vocal changes in a female's voice are too inconclusive to make any determinations.
Research published in the journal PLoS ONE examined the variation of a woman's voice throughout her menstrual cycle. The study's authors were able to note that the changes that take place do not indicate when a woman is ovulating. In fact, women spoke with the highest tone just before they were ovulating. That same pitch returned after the ovulation was complete.
The study's authors noted that in other species, this would be considered a poor mating call, as it is unlikely that the female is ovulating as their pitches change. Additionally, the study's authors noted that men only had a slight preference for the highest tone before ovulation over the tone the woman had during the reproductive process.
However, aside from the change in tone, researchers found that overall, women who were in the process of ovulation had harsher voices. This could also cause them to have irregular pitches. The study's authors took this as scientific backup as to why opera singers are allowed grace days while they're menstruating.
Overall, men who are worried about getting their partner pregnant should practice safe sex techniques such as using condoms in order to limit the possibility of an accident occurring. Condoms have been found to help prevent unplanned pregnancies, which may be more of a sure thing than waiting to see if a female's voice changes when she's at the highest risk of conception.
