Varicoceles- A varicocele is a swollen, varicose vein located in the scrotum. It is not uncommon for men to have a varicocele and roughly 15% of men have one. These swollen veins can affect how the sperm are able to be released from the testicles. If a varicocele is affecting fertility, it may be corrected surgically or the couple may opt for intrauterine insemination to get pregnant, which injects the sperm directly into the uterus, bypassing the vaginal canal.
