Low motility due to vein

Theodora • TTC # 1 IVF 🙏 Unexplained infertility/endometriosis

“A varicocele (VAR-ih-koe-seel) is an enlargement of the veins within the loose bag of skin that holds your testicles (scrotum). A varicocele is similar to a varicose vein you might see in your leg.”

My fiancé has this and I was wondering if anyone has any experience with how to help it. It’s preventing us from getting pregnant. Any advice and I would be so grateful
