The Power of Semen

Originally published on September 19, 2012, on bedsider.org

Just when we thought we had the biology of human reproduction figured out, new research shows there’s still plenty we don’t understand. Today’s example? A team of biologists have shown that a protein commonly found in the semen of many animals—including humans—can help kick-start the release of an egg (a.k.a. ovulation). The protein, which has been on biologists’ radars for a long time, is called beta nerve growth factor, or β-NGF—named for the first thing scientists noticed it doing.

Studies in llamas, alpacas, and cows show that giving β-NGF as a shot leads to the release of an egg in most of the animals. But what about humans? We know there is β-NGF in human semen too, but we don’t know whether it does something similar in humans as in the animals the scientists tested it on. The researchers hope to tackle this question next.

The answers they find will help determine how reliable the rhythm method (a.k.a. fertility awareness) can be as a form of birth control. It could also suggest a new treatment for couples struggling with infertility… We’ll be keeping our ears open!

I have no words to express my gratitude, Eka the great priest of Eka kingdom...I have fought with infertility issues for more than a decade. My Gyn told a year ago that one of my tubes was blocked, and had insisted that IVF was the only option left for me. I was desperate and terrified due to my relatively advanced age (I was 38 a year ago) and the 2 ovarian cysts that were giving me hell, that I would be childless. My husband and I decided we will keep on fighting as I have read many awful stories about the side effects, the low success rates and pain involved with the IVF procedure so we kept looking for a way out to have a child of our own. We almost gave up and then I found the email of priest Eka (dreka14demons@gmail.com) and I emailed he for help and he told me all what I will do for him to cast me a pregnancy and pregnancy protection spell. And kindly I immediately ordered him to do all the needful for me to get pregnant and I did everything Eka said along with my husband who had poor sperm motility. After two months of trying I got pregnant with my first baby boy. With one blocked tube and 2 ovarian cysts, I think this is nothing short of a miracle! I will thank Eka for everything, Contact him (dreka14demons@gmail.com)
