TTC ADVICE APPRECIATED

We need advice from anyone in a similar situation to ours.
Male: Low sperm motility, sperm count okay but many non-viable sperm.
Female: Irregular cycle length 25 and 32 days alternatively, ovulate alternative months.
Been trying naturally for >4 years and have one failed IVF behind us (9/11 eggs fertilised by ICSI, most embryos formed but then stopped, no resultant pregnancy).
This is all new information after being under hospital for >5 years.
Please help we are desperate!
