There are many things that can cause low fertility rates in men. While factors such as disease, heredity and genetic-based conditions are sometimes the root cause, there are times when general health issues are to blame. Improper diet, taking certain medications, smoking and other lifestyle factors can also affect male fertility.
A recent study conducted at the University of California suggests that men who frequently use hot tubs are more likely to experience decreased semen quality and lower fertility rates.
From Reuters Health:
"Male fertility plunges with frequent dips into the hot tub but may recover when men stay away from long hot soaks..."
The study included 11 infertile men and was performed over a period of 3-6 months. The data collected seems to confirm that regular periods of elevated temperature, such as from hot baths, does in fact affect sperm quality.
Not all candidates however experienced a significant increase in sperm count or quality. In these cases, contributing factors such as smoking seem to be the likely cause.
Here's an interesting little fact:
"...a normal healthy man makes 1,200 sperm per heartbeat."
Pretty impressive, but I don't think my girlfriend will buy that as an excuse for being tired!
If you'd like to learn more about causes of male infertility, I suggest reading the past blog post entitled "Male Infertility Problems."
