A new study has just been published in the Journal of Human Reproduction, which for the first time indicates a relationship between Vitamin D and calcium deficiency in men with poor Sperm quality and an imbalance in male sex hormones.
Men with normal levels of Vitamin D and Calcium (based on blood tests) had higher numbers of sperm with normal motility. Motile (swimming) sperm are the only type of sperm that can acheve a pregnancy. Good sperm motility is required in order for the sperm to travel from the vagina, through the cervix and into the fallopian tubes where an egg will be waiting after ovulation.
This study highlights the importance of a balanced diet for correct functioning of the male reproductive system. Key nutrients such as Vitamin D and Calcium can be taken in the form of supplements to ensure that normal levels are maintained.
