i found this on another forum and it was interesting and thought to post it to ttc ladies on bnb
it actually makes sense to me what do you think????
"Say you DTD the night of a positive, that deposits approximately 40 million sperm (a lowball amount of sperm in ejaculate, so that I'm not giving best-case scenario. Men tend to ejaculate 2-4 mL, with anywhere from 20 million sperm per mL to over 100 million per mL if they fit into lab norms). Then you DTD the next night, 40 million more. Now there's about 80 million sperm waiting to fertilize the egg.
Now, let's look at the other situation: say you DTD the night of a +OPK (40 million sperm) and then the next morning, 7-8 hours later. Even if we say that the second ejaculation is reduced by 10%*, that still means 36 million additional sperm are hanging around. Then you DTD a third time that night; 10% less than the previous (since we're in a less-than-24-hour window between ejaculations again) still adds 32.4 million more sperm. So that's 40 million + 36 million + 32.4 million for a total of 108.4 million sperm to potentially fertilize the egg, versus just 80 million if you skip the morning quickie.
(*10% is a conservative estimate of the amount by which frequent ejaculation would reduce the sperm content of the next ejaculate. Most people think the effect is less than that, meaning the actual number of available sperm would be even higher in the second scenario.)
The bottom line is that more BDing = more sperm available, even for men with problems with their sperm count (and I looked into this pretty extensively, as my DH is one of those men). The notion of both needing to, and being able to, "save up sperm supply" is controversial. More ejaculations result in more total sperm hanging out in the female, even when later ejaculations have lower concentrations. Besides, sperm, like breastfeeding, is supply and demand; there's even good evidence to suggest that infrequent ejaculations affect sperm quality more than frequent ejaculations affect quantity. It's actually not uncommon for a urologist to recommend that a man ejaculate at least once every four days throughout a woman's entire cycle in order to keep up "demand" and quality. Because sperm take weeks to make, today's quantity and quality reflect the demand about 8 weeks ago, so attention to ejaculation frequency while TTC needs to take place all month, not just during the short fertile window."
