hi there, am dr.surendran nice to meet you here in HCMagic Exercise regularly but the intensity and duration should be moderate and under supervision, if possible. Excessive physical exercise has a negative influence on fertility. Lose excess weight, as it tends to cause testosterone/estrogen imbalances. Eat nutritious food, which is low in fat and high in protein, vegetables and whole grains. Reduce caffeine intake. Avoid excessive usage of lubricants and vaginal tablets, they can also cause sperm death. Do not store your cellphone in the trouser pocket, or place your laptop on your lap. Protect testicles from too much heat. Avoid high temperature conditions. Once in a while it is fine to take steam baths, spas. Wear loose undergarments. Reduce stress levels by learning relaxation techniques like yoga and meditation. Take a conscious effort to balance the physical and mental health. Physical fitness and mental relaxation improve male fertility. Anabolic steroids should be taken under the guidance of a proper doctor as it can lead to Azoospermia, the term used when there is a complete absence of sperms. Intake of vitamins like Vitamin C, Vitamin A, Vitamin E and Zinc should be regular. Reactive oxygen species (ROS) are present in the semen. When the ROS are present at a high level it can result in significant damage to the semen. Vitamins can decrease the level of ROS. Vitamins help in synthesis and development and maintenance of the normal sperms and they help in avoiding the clumping of sperms. hope i helped with your query, with regards dr.surendiran [hcmagic]
