Welcome to HCM.
After the age of 37-40 years, chance of conception rapidly declines because of reduced egg content of ovary. Even when everything is fine, chance of conception at age of 42 is less than 10%. Over & above that, your husband has poor sperm motility
& morphology, which will further reduce chance of natural conception to say In this situation, its best to go for advanced treatment like repeat ICSI
with own/donated eggs depending on your ovarian reserve
Wish you good health.
