This is for ttc a girl. There are no studies to back it up and when people refer to J&D they could be talking about 2 things:
- To jump up right after sex and run to the toilet; dumping all sperm in there. The theory is you are dumping out the y sperm and only the x remain. But there is no evidence of this.
- To have dh release and not use that sperm. Then have dh release a second time and use that sperm. This would lower sperm count but would be counterproductive if you had him abstain for over 7 days.
