ok my turn to chime in with lots of info since my wife & i are adopting because my sperm count is at the big ole 0 LOL
for starters, when trying to conceive, do not have sex either with your partner or your hand for a timeperiod of 3-5 days prior to her peak ovulation time which is 9-13 days after her period starts. on day 9 start humping only once every 24-36 hours. it will make no difference if you hump 4 times per day or once every 24-36 hours because you will not be giving your sperm enough time to bring the count back up sufficiently. also have the fertility doc check the motility(movement) of the sperm. it is best to get an ovulation measuring device, my wife used an (ovulite) which she purchased on-line.
for your sake, to try and increase your sperm production, use hcg at 500iu per day for a period of 3-6 weeks. also get on avena sativa, tribulus, & long jack folia right away as these will help to increase your natural test rpoduction and also help to stimulate the tyroid to produce lh & fsh. stay away from caffeine as much as possible as this will also affect your sperms ability to perform. also have your partner stay away from caffeine as much as possible. here are some great websites to check out:
