For any of those who are dealing with the dreaded diagnosis of "unexplained" infertility, this article on sperm proteins might give you some additional things to ponder. Not that it provides a therapy, mind you. I'm wondering if that was our problem because IVF with ICSI seemed to do the trick very nicely, and my body seems happy with the whole idea of pregnancy. Or perhaps I just have really mean eggs that bitch-slap any sperm that get too close to them but were lulled into compliance once the projesterone started flowing. I mean, hell, "unexplained" really opens the door for creativity, right?
As a funny aside, the last article in this issue of ScienceNOW is about the birth of stars (the ones in the sky, not the Hollywood crowd) and is called "A Hot Stellar Womb." The editor must have had fun this month.
