Although often overlooked as a factor in male fertility the sperm morphology plays just as important a role as the speed, concentration, count, and motility of sperm. Sperm morphology is the term used for sperm size as well as shape. To be classified as a healthy sperm, the shape and size should be correct. The sperm should look like a little tadpole with the head being an oval shape and the centre area thinner with a tail. The head contains the genetic material whilst the centre contains the energy and the tail acts as the propeller to drive the sperm forward. Studies have shown that abnormal sperm morphology will ensure unsuccessful penetration. The Pregassist supplement will help to also improve the sperm morphology and thereby improving the chances of successful penetration, fertilization and thus conceiving by couples.
