Night shifts, heavy lifting impair women’s fertility: study

Night shifts and heavy physical labor makes female workers less fertile than other women, according to a new research.

A team of experts led by Lidia Minguez-Alarcon, of the Harvard School of Public Health in Boston, found in the new study that those women who worked at night or did heavy lifting on their jobs had fewer “mature” eggs. As a result, they had lower chances of having a baby.

However, Minguez-Alarcon admitted that some of those women might be exposed to some other environmental factors that could affect their “egg quality.”

Dr. James Grifo, the director of the NYC-based NYU Langone Fertility Center, also pointed out that the study didn’t show that women’s job situations openly affected their chances of getting pregnant or having a baby.

Making arguments against the study’s findings, Grifo added, “Do you tell women to quit their jobs or to stop lifting based on this? I don't think so.”

The findings are based on the study of nearly five hundred women who underwent in vitro fertilization (IVF) at an infertility center.

The new research was detailed in the Tuesday (Feb. 7th) edition of the journal Occupational & Environmental Medicine.
