there would definitely be more sperm in the first "load" then then 2nd. Sperm are created in the testicles but have to travel quite a ways thru the vas deferens (sp?), it goes up from the testicles, over the bladder, and hooks up with a few glands (including the prostate) that produce the seminal fluid for the little guys to swim in, on the way back down to the exit point. It takes 2 - 3 months for sperm to get from point a to point b and the longer he abstains the more sperm there are (theorectically) but if the man abstains too long some of the sperm can become abnormal or the morphology or something goes down. But sperm are continually being created so there should always be some guys there, barring any medical reasons. Some dr's will tell you it's best (for TTC chances) to go every other day, and for doing a S/A some places will tell you to abstain for 5 - 7 days, and some will tell you 2 - 3 days.
but yes there would be less sperm in a 2nd (or 3rd??

) ejaculation.
(DH says "not normal" but i think he's just jealous!!!

it's been a loooooooong time since he could do that! GO DWAYNE!!!!!
