New sperm structure found maybe linked to infertility: Study

A US-based study found a new centriole, a sperm structure which may contribute to research on infertility, miscarriages and birth defects. The centriole is the only essential cellular structure contributed solely by the father for building the cell's skeleton and antennae known as cilia. Researchers found that a father donates not one, but two centrioles through the sperm during fertilisation.
