Hi Arch - just to add my 2 bits, they can't tell much from one SA - it's worth having a couple to see if there's a general picture (though often there's not!).
My DH's first SA result a year ago was 11 million, 20% morphology, 32% motility. By this point he hadn't had a drop of alcohol or caffeine for 2 years and was taking Wellman Conception, Pycnogenol, high dose vitamin C and E, selenium, Omega 3, 6, & 9, etc. Healthy diet, regular (though not too strenous) exercise, showers instead of baths, boxers instead of briefs, no phones in pockets, laptops on lap, etc. We were desperate and had been doing everything by the book. Lifestyle-wise, there really wasn't much room for improvement.
All my tests were fine. They declared DH clinically subfertile and said our only choice was ICSI. We dragged our feet - we'd been pregnant before naturally ( after 2 years ttc) but lost the baby. We kept thinking we weren't infertile, there must be a way without IVF if we just gave it a bit more time...
The next SA was 21 million, and 51% motility but only 3% morphology, and anti-sperm antibodies. We hadn't changed anything, lifestyle-wise, in that time - he was on exactly the same cocktail of supplements, same healthy diet, same total abstention from caffeine & booze. So it was nothing he did or didn't do that caused the count to double - or the % of normal forms to plummet so dramatically, or the antibodies.
We discovered he had a testosterone level that was on the lowish end of normal, and certainly low for his age. So he took Clomid for 4 months (this is used in the US sometimes to raise testosterone levels & has had some success with improving sperm quality). Next SA was 24 million, 4% morphology, 51% motility, and no anti-sperm antibodies. But he'd become a raging aggressive maniac, so I made him go off it. I've come to believe that low testosterone is the key to a happy marriage
.
Between the first SA and now, we've had 2 pregnancies - but both have miscarried. I'm 39 next month. Started TTC 5 years ago, and always thought it would work for us if we just changed our diet, took more supplements, etc. Kept thinking, am I not doing enough yoga? Should I make DH do yoga? Should we live as though we have diabetes? Would that help? Should we pee on these PH sticks twice a day to see if we're alkaline enough? Should I up my intake of wheatgrass shots? Might colonic irrigation help?
I'm starting IVF next week.
So my advice would be - if there are lifestyle changes your DH can make (biggest one I'd say is laptop on lap - thighs are close enough to jewels to be cooking the contents!), then go for it, particularly if it'll make you healthier & happier in the long run. But don't beat yourselves up - there's so much that's beyond our control, and so, so little is known about male fertility in particular. If you're doing the basic things and getting nowhere, accept help.
Good luck!
