Pre-operative laboratory tests for vasectomy reversal surgery

No specific laboratory tests are required before doing a vasectomy reversal surgery. Standard tests required by the anesthesiologist, such as an EKG maybe done.

Antisperm antibodies

Antisperm antibodies are proteins which inhibit the movement and function of sperms. Almost all men who have under gone a vasectomy have antisperm antibodies in their blood. While the presence of antisperm antibodies in the blood of the man does not hinder fertilization (union between egg and sperm to form a zygote), the presence of antisperm antibodies in the ejaculate (semen) after vasectomy reversal could immobilize or kill the sperms.

Tests for antisperm antibodies are not routinely done before vasectomy reversal surgery. Studies have shown little co-relation between pre-operative assay for antisperm antibodies in the blood and pregnancy.

Follicle Stimulating Hormone (FSH) assay

Follicle Stimulating Hormone (FSH) is a hormone produced by the pituitary gland. It stimulates the testes to produce sperms. A high FSH level in the blood suggests reduced sperm production, and the prognosis for obtaining good sperm count after vasectomy reversal is poor.

FSH assay is not routinely done before vasectomy reversal surgery. It may be indicated in men who have not fathered children before their vasectomy, in men with small, soft testes, and in men whose vasectomies were done many years ago.

Glossary of terms used in this page:

Anesthesiologist: Anesthesiologist is a doctor who specializes in giving drugs or other agents to prevent or relieve pain during surgery or other procedures being done in the hospital.

EKG: EKG (Electroencephalogram) is a test which measures the electrical activity of the heart.

Epididymis: Epididymis is a tube-like structure which connects the testis and the vas deferens. The sperms are stored and matured in the epididymis.

Hormones: Hormones are chemical messengers that control various bodily functions.

Sperms: Sperms are male reproductive cells. They are produced in the testes. They are carried in fluid called semen. Sperms are capable of fertilising an egg cell to form a zygote.

Testes: Testes (singular=testis) are the male gonads. They are situated in the scrotum. They produce sperms and the male hormone, testosterone.
