Grace is having her second baby and she appeared all sharp in the hospital ward. “How are feeling madam?”, the doctor asked. “I am alright and ready to push”, she replied. After getting examined by the midwife, Grace spotted an old friend of hers lying on the bed next to hers who had been admitted three days ago with a full-term pregnancy, but was anxiously awaiting her labor to begin.
But how do these events occur? An international team of scientists has started to shed light on this by identifying a protein called NELL2.
NELL2 is secreted by the testes and travels to the part of the male reproductive tract where sperms are stored after they are released, the epididymis. This protein literally turns on the maturation process of sperms, getting them ready for fertilization. The study team found, also, that if this molecule is not functioning well or is deficient, it may lead to male infertility.
These findings could help scientists create new ways to diagnose and treat male infertility. Read more here – https://www.bcm.edu/news/novel-switch-protein-turns-on-sperm-for-fertilization
