Sperm count

We all know that shift work can have a negative impact on some ones social life, but the working lifestyle could also have an impact on male sexual health. 

Shift work and its associated sleep disorders may actually significantly impact a man's sexual and urologic health, researchers from the Baylor College of Medicine in Houston have found. 

According to MedPage Today, non-standard shift workers were more likely to have lower urinary tract symptoms including prostate issues.

'Non-standard shifts have been shown to be associated with increased risk of hypogonadal symptoms and sexual dysfunction,' said Will Kirby, MD.

The issues associated with the shift work also included lower levels of sperm density, motile sperm count, and testosterone levels, which could lead to a lower sex drive and lead to difficulties having children. 

The study included 2,487 men who completed questionnaires that assessed their work schedules.

Of the shift-working men, 37 per cent had these issues, along with excessive daytime sleepiness and difficulty sleeping, the authors said in a presentation at the American Urological Association annual meeting.

'That was a surprising finding for us,' said Will Kirby, MD.

'We believed the total motile count would decrease with less sleep.'


If you and your partner are hoping to start a family, there's a pretty high chance you have already researched the various external factors in both your lives which may impede progress on the baby front, right?

But did you know that the time in which your partner's head hits the pillow can actually play a part in the likelihood of you conceiving?

According to a recent study conducted in China's Harbin Medical University, men who decide to call it a day before midnight have a better chance of conceiving than their counterparts who are only winding down at 1 or 2 in the morning after a fairly heavy boxset binge.

With the participation of 981 healthy men, researchers investigated the theory that there exists a link between sleep patterns and sperm mobility.

Dividing the men into three groups, researchers instructed the first to go to bed between 8pm and 10pm, the second between 10pm and midnight, and the third after midnight.

In addition to this, they were instructed to set their alarms to ensure a nine-hour sleep, a seven-to-eight hour sleep, or a six-hour sleep, and findings indicated that those who went to bed after midnight or slept for just six hours had lower sperm counts.

After analysing sperm count, shape and motility, researchers established that shorter sleep cycles affected sperm count as they increase levels of antisperm antibody which is a type of protein produced by the immune system known for destroying healthy sperm.

The findings were published in the Medical Science Monitor.
