Orchiectomy Health Article

Definition

Orchiectomy is the surgical removal of one or both testicles, or testes, in the human male. It is also called an orchidectomy, particularly in British publications. The removal of both testicles is known as a bilateral orchiectomy, or castration, because the person is no longer able to reproduce. Emasculation is another word that is sometimes used for castration of a male. Castration in women is the surgical removal of both ovaries (bilateral oophorectomy).

Purpose

An orchiectomy is done to treat cancer or, for other reasons, to lower the level of testosterone, the primary male sex hormone, in the body. Surgical removal of a testicle is the usual treatment if a tumor is found within the gland itself, but an orchiectomy may also be performed to treat prostate cancer or cancer of the male breast, as testosterone causes these cancers to grow and metastasize (spread to other parts of the body). An orchiectomy is sometimes done to prevent cancer when an undescended testicle is found in a patient who is beyond the age of puberty.

A bilateral orchiectomy is commonly performed as one stage in male-to-female (MTF) gender reassignment surgery. It is done both to lower the levels of male hormones in the patient's body and to prepare the genital area for later operations to construct a vagina and external female genitalia.

Some European countries and four states in the United States (California, Florida, Montana, and Texas) allow convicted sex offenders to request surgical castration to help control their sexual urges. This option is considered controversial in some parts of the legal system. A small number of men with very strong sex drives request an orchiectomy for religious reasons; it should be noted, however, that official Roman Catholic teaching is opposed to the performance of castration for spiritual purity.

Cancer

There is no effective alternative to radical orchiectomy in the treatment of testicular cancer; radiation and chemotherapy are considered follow-up treatments rather than alternatives.

There are, however, several alternatives to orchiectomy in the treatment of prostate cancer:

• watchful waiting
• hormonal therapy (The drugs that are usually given for prostate cancer are either medications that oppose the action of male sex hormones [anti-androgens, usually flutamide or nilutamide] or medications that prevent the production of testosterone [goserelin or leuprolide acetate].)
• radiation treatment
• chemotherapy

Gender reassignment

The primary alternative to an orchiectomy for gender reassignment is hormonal therapy. Most patients seeking MTF gender reassignment begin taking female hormones (estrogens) for three to five months minimum before requesting genital surgery. Some persons postpone surgery for a longer period of time, often for financial reasons; others choose to continue on estrogen therapy indefinitely without surgery.

Description

There are three basic types of orchiectomy: simple, subcapsular, and inguinal (or radical). The first two types are usually done under local or epidural anesthesia, and take about 30 minutes to perform. An inguinal orchiectomy is sometimes done under general anesthesia, and takes between 30 minutes and an hour to complete.

Simple orchiectomy

A simple orchiectomy is performed as part of gender reassignment surgery or as palliative treatment for advanced cancer of the prostate. The patient lies flat on an operating table with the penis taped against the abdomen. After the anesthetic has been given, the surgeon makes an incision in the midpoint of the scrotum and cuts through the underlying tissue. The surgeon removes the testicles and parts of the spermatic cord through the incision. The incision is closed with two layers of sutures and covered with a surgical dressing. If the patient desires, a prosthetic testicle can be inserted before the incision is closed to give the appearance of a normal scrotum from the outside.

Subcapsular orchiectomy

A subcapsular orchiectomy is also performed for treatment of prostate cancer. The operation is similar to a simple orchiectomy, with the exception that the glandular tissue is removed from the lining of each testicle rather than the entire gland being removed. This type of orchiectomy is done primarily to keep the appearance of a normal scrotum.
