When pig IVM oocytes were incubated for 30 min in bOF with a mixture of proteinase inhibitors, the ZP did not dissolve even after min in pronase solution, compared with 1 min in control oocytes. Some research has also shown that being overweight or obese affects a man's sperm quality , reducing sperm counts and decreasing their ability to swim, as well as increasing damage to genetic material DNA in sperm, according to the American Society for Reproductive Medicine. These two issues suggest that in the mouse OGP is unrelated to ZP resistance to proteinases or to sperm—ZP binding, as has been recently described Elena Koshka leaking cum out of her tight pussy.

But there are many steps that men can take to enhance their health, lifestyle and relationship to increase a couple's chances of conceiving.
