Hi Tsf0205, seeking alternative doc's opinion or consulting an urologist might be a good idea.
My DH SA was really bad- count & concentration way below normal & morphology 0% based on Kruger's strict criteria. 0% is round off based on millions or hundreds of thousands in total; it doesn't mean exactly zero morphologically normal sperms. In ICSI, they select the most normal sperms from healthy motile sperms that swim out of the semen on their own. So long as there is one such selected sperm per egg for injection & fertilization, sperm issue is not hopeless. My ivf doc never raise issue with sperms since we proceed with ICSI.
Agree with Bunny & hengcai that sperms may improve. DH sperms did improve over time & by latest 3rd ICSI, though still 0% morphology, count & concentration improved way beyond normal criteria. This increases the pool of sperms for lab to select best sperms. DH started TCM since jan'15 and stopped after the last ICSI as we wil be going for FET next cycle. TCM doc said he can rest since generally healthy already and if need again for future ICSI, can restart as acupuncture is not meant to be forever non-stop measure.
DH also improved lifestyle habits, watch diet but not extreme so can sustain (still hv his daily morning teh but no cold or sugary drinks, eats home-cooked meals on weekdays dinners and on wkends as much as we can), exercise 2-4 times weekly.
One thing we did replaced water bottles and home food storage containers with glass type. He used to drink v frequently from plastic bottles. We also change to natural phthalates free detergent & shower gel. I stopped perfumes & nail polishes (but must still cover grey hairs haha). BPA, phthalates & pvc are proven damaging for fertility. We try to adopt what is beneficial to our health & hope for the best. When we see improvement, we can't pinpoint what it is but something must hv gone right and hope to get closer to our goal. Even if not, we console ourselves that we hv done our best.
Don't give up. Jia you k.
