RE "unexplained fertility" - exact same thing happened to us.
We waited until we were "ready" (are we ever "ready"? certainly didn't feel like it when the baby arrived!) but it took about 4 years to actually have the baby. Miscarriages, then just nothing apart from endless mechanical & unromantic sex day after day after day for years, with deeply upsetting emotional consequences when nothing happened.
Everything checks out medically and the doctors cheerily just say "keep trying!" but then write "unexplained infertility" on your report as you plod back home for more fruitless intercourse. No one can explain why it is not working as the usual battery of tests they do come back fine ... you begin to envy and resent people you see who are pregnant, you cant look at a cute puppy/kitten because you feel like you'll never have a baby, you simmer with inner rage when someone at work brings in their baby to show around the office, or someone mentions their kids etc ..."HoW cAn thEYy bE sO INSENSITIVE?!?!?!?!" you fume to yourself as you die a little inside. It is quite the existential torture.
To HNers reading this: If this sounds like you, please do yourself a favor and find a clinic that deals with immune-related infertility. During consultations for starting IVF, one clinic casually noted that my wife had "natural killer" CD16+ and CD56+ cells that might be causing the miscarriage and no natural pregnancies. We immediately found a clinic that specialised in treating that condition and 2 months later we had a natural pregnancy that went full term - our baby boy was born 1 year ago and he is thriving. After 4 hard years of sorrow and misery, it just took some basic immune-modulating drugs and we got pregnant naturally after just two months, and a totally textbook baby (straight down the middle on weight & size etc) was born naturally with no complications. It can happen - good luck.
Similar for us - trouble conceiving and a miscarriage. Months spent improving sperm. All conventional checks on mother came back as fine - "keep trying!" they kept telling us, while writing "unexplained infertility" on our medical records.
Still nothing happening. IVF was on the horizon, but a private consultant identified some trouble with "natural killer" cells in mother. No other issues with mother (no cancer like parent post)
Prednisolone (IIRC) and some lipid infusions and baby was conceived and delivered naturally. Drugs cost maybe £80 a month (although all the diagnostic checks and stuff was much more - start to finish (including like 12 ultrasound checks and multiple sessions with the consultants) we spent perhaps about £8-10K) - conceived on second month of trying, after years of nothing apart from a miscarriage and intense sadness.
Similar anecdote from a UK-based late-30s guy with a BMI in the 30ish range:
- no background health/illness issues. Non-smoker, occasional drinker (2-3 glasses a week).
- trouble with getting pregnant - checks on female were all A-ok.
- sperm analysis on me done.
- count & motability fine.
- morphology was low at 1% good-forms (minimum is IIRC 3% or above).
Several months later and re-tested: morphology was then at 4% - count & motability largely unchanged. DNA fragmentation was "normal" but not amazing (not tested initially)
What I did:
- significantly upped my standing desk usage - from sporadic use a few times a week, to perhaps 25-50% of every working day at a standing desk.
- changed underwear from tight-fitting "trunks" to looser "jersey" (not boxers - personally I hate boxers)
- slept naked instead of wearing trunks.
- almost entirely eliminated alcohol and caffeine, apart from the odd glass/cup maybe once or twice a month.
- anti-oxidant tablets ("condensyl") taken daily
Notable:
- exercise & weight largely unchanged (I ran a few KMs maybe once or twice a week - this remained unchanged)
- diet (apart from caffeine and alcohol) largely unchanged - perhaps some small mild "improvements" in cutting back on sugar & fat and having more veg but nothing drastic or wildly different really.
I now have a naturally conceived 1 year old boy. Pregnancy + birth + delivery totally normal, baby all A-ok. It can happen - don't loose faith if the results are "bad". Good luck.
