Yes, moving your clock forward not only makes your sleep shorter, the time change can also be risky to your pregnancy. Since 1978 scientific research has established that human fertility aligns with the circadian rhythm, the daily rotation of the Earth. The cycles between the daily, seasonal, and annual patterns of light and dark influence our biological and neurohormonal chemical system. In other words, according to the in-fertility online research our fertility does depend a lot on light, regurlarity and good sleep, reducing the stress level.

However, it does not only apply to women. Several studies have provided evidence that simply getting 20 minutes of daylight exposure each morning can raise testosterone levels as much as 30%.

A number of studies have also reported a higher percentage of early foetal loss, preterm births, and lower birth weights for those women who work during the night time hours normally assigned for sleep. It does come little surprising that time change also has negative impact on our fertility.

Boston Medical Center (BMC) researchers found that miscarriage rates in IVF patients who had a prior miscarriage were much higher among those who received an embryo 21 days after the spring time change than those whose embryo transfers were conducted before or nowhere near the time change.

Researchers evaluated its impact on 1,654 IVF patients between 2009 and 2012 who had previously had a miscarriage.

The scientists, who were researching the impact of daylight savings time on pregnancy loss said the results were intriguing, however, they need to be replicated in larger cohorts in different parts of the world observing the time change.

The news comes just weeks after it was claimed that thousands of British women are having IVF unnecessarily when they are able to have a child naturally. Professor Siladitya Bhattacharya, from the University of Aberdeen, said the problem is couples expecting to start their family ‘on demand’.

It is believed that the irregular exposure of light and darkness is the primary reason for several conditions, for example an increase in breast and ovarian cancer. In 2007 the World Health Organization had determined that due to circadian dyschronization of light at night, working the night shift is now classified as causation factor in breast cancer for both men and women.

If you are undergoing IVF these days, make sure you stick to your regular sleep pattern, which may help. Try to avoid stress or use stress eliminating techniques. By the was, examining three key reproductive hormones, Reinberg et.al had demonstrated a 95% confidence rating establishing Autumn as the season of choice for human male fertility and also for the ability of women impregnated during this period to carry full term.
