The testes are located outside the body to maintain a slightly lower temperature, which is optimal for sperm production. A number of studies suggest elevated temperatures can impair sperm quality, as sperm production is highly sensitive to temperature. High temperatures, such as those found in hot showers, saunas, hot tubs, can negatively affect sperm parameters and may lead to low sperm count or oligospermia.
Low sperm count directly impacts fertility. If the numbers of sperm are less, the chances of fertilizing the egg also decreases. However, low sperm count doesn’t only reduce one’s chances of becoming a parent. Interestingly, the implications of low sperm count extend beyond reproductive health. Emerging researches are increasingly indicating that reduced fertility in men can impact cardiovascular health.
