So maybe that's what we've been doing wrong?

Perhaps it explains why some women end up with babies without even trying or wanting them, when others try diligently for years without any success.

But now does it have to be all at once, or serial???

Do you have multiple partners around the same time, or does having different partners, one after another, make the difference?

Marsupial Mating Proves Promiscuity Pays

SPEED MATING: Mouselike marsupial Antechinus stuartii, blending in with a tree trunk (pictured above), practices polyandry. Once in their lives, males copulate with as many females as they can over several hours.

Studies in insects have shown that such promiscuity, known more technically as polyandry, or multiple fathers, produces better young -- better in this case being a measure of offspring survival. Some have proposed that males with more competitive sperm create more viable offspring, but this hypothesis has yet to be unequivocally demonstrated, largely because it is difficult to distinguish whether such survival is the result of better fathers or more mothering from females.

About Catherine: I am mom to three grown sons, two grandchildren and two rescue dogs. After years of raising my boys as a single mom, I remarried a wonderful man who had never had a child of his own. Unexpectedly, I found myself pregnant at 49!
Sadly we lost that precious baby at 8 weeks, and decided to try again. Five more losses, turned down for donor egg, foster care and adoption due to my age and losses - we have accepted that there will be no more babies in our house.
