should not impact your fertility as the hormones effected by it play minor roles in overall fertility. The fact that DAA may help with the synthesis/release of LH, along with a reasonable increase in test leads me to believe the potential detriment to your fertility is negligible (if not a possible benefit). You will want to incorporate something to manage your prolactin, as this would be the one factor that may have a negative impact. Something like L-dopa, , etc. should do the trick.
You have factors like morphology, concentration, motility, free radical/leukocyto ratios...mind you spermatogenesis is a 3month process, so youre initial ejcaulations are not likely to have any residual effects from the supplements anyway. I would not expect it to have an adverse effect, but when it comes to starting a family, and based on the assumption that lifting weights does not pay your bills...it cant hurt to hold off for a few months, and go from there.
On a side note, I have been working on a research project in my lab (andrology) to use the treatment of antioxidants ( I was looking at R-ALA + ALCAR as they have a known synergy) to act as nullifying agents of leukocytes (responsible for free radicals which impact motility amongst many other vital parameters) to increase motility and maintain DNA integrity of spermatozoa. So feel free to add in plenty of , ALA, ALCAR, and any other antioxidants you're a personal fan of, it may help and cannot hurt.
