Sorry for the misspelling iet varicocele. This s varicose vein of the testicles which cause increased heat and therefore decreased normal sperm ie poor morphology. I suggest seeing a specialist in male fertility like a urologist and do a work up. If they can find nothing to improve the morphology then you may have to do IVF with intracytoplamsic sperm injection. I presume you are interested in fertility. If you are not interested in fertility then you can try testosterone replacement to improve libido and ED.
It could be related to the hypthyroidism and I hope you have started thyroid replacement then you should recheck your testosterone and if it is still low, you may try to have replacement. However, if you are trying to get pregnant then you should not be on testosterone replacement and instead need to work up for poor morphology like a varicocle.
