A study of 794 men published in FERTILITY AND STERILITY reported that obesity may affect the quality of a man's sperm. The study was led by Ana Carolina Martini, PHD, biolgist, Physiology Institute at the School of Medicine, National University of Cordoba in Cordoba, ARgentina.
The study indicated that obese men's semen had lower amounts of the enzyme neutral alpha-glucosidase (NAG). NAG is involved in sperm maturation. In addition, obesity is associated with fewer rapidly moving sperm and with fewer sperm that swim forward in a straight line.
This is just one study. But for those obese men hopng to improve chances of fertility, losing weight may be a way of improving sperm quality. If you or your partner is obese and you have been struggling with infertility, hypnotherapy can be a valuable tool to assist in losing weight for general health and to improve sperm motility and maturation,
