A new study from the Harvard Public School of Health reveals that women who have physically demanding jobs or who work during the night might have decreased fertility. The study shows that women working such jobs have lesser mature oocytes than women working 9-to-5 jobs.
Lidia Minguez-Alarcon of the Harvard Public School of Health revealed that during a recent study involving over 500 female patients, she and her team revealed that women currently engaged in physically demanding jobs or those forced to work night shifts might be less fertile than women who work during the daytime.
Minguez-Alarcon, who’s also the study’s lead author, stated that women occupying these positions have less mature eggs, which translates as fewer chances of conceiving a baby via IVF.
Despite the fact that the study’s results pointed out that there’s a connection between the quality of work and the chances of conceiving via IVF, Minguez-Alarcon and her colleagues declared that the study should be taken with a grain of salt.
More specifically, the study underlined a possible relation between occupation and fertility but did not state for a fact that night shift or physically-demanding job makes women less fertile. The study’s author said that other environmental and possibly genetical factors might be at work here, but the study opens up new avenues of the investigation.
Dr. James Grifo of the NYU Langone Fertility Center, who was not involved in the recent study, said that that Minguez-Alarcon’s findings were indeed intriguing, but that they should not be taken for granted. Grifo voiced his concern over the possibility of the findings to upset further some patients who might blame the failure of their fertility treatment on the study.
James Grifo, who’s also the director of the NYU Langone Fertility Center, declared that the data is compelling, but it is certainly no basis to tell women to quit their jobs.
According to the team’s finding, women who either had physically-demanding jobs or were compelled to work night shifts had on average two less mature oocytes than women who had a 9-to-5 job.
Professor Adam Balen of the British Fertility Society declares that the study’s results are indeed worth the consideration, but that more research needs to be done. Balen added that study should have taken other factors into consideration such as smoking during pregnancy.
For now, Minguez-Alarcon’s team is still collecting more data on the subject.
