And it has this paramount advantage that, whereas vasectomy being an occlusion of a secretory duct, leads to complete atrophy and destruction of the testis, ligature of the Fallopian tube, which is only a uterine appendage and not a secretory duct of the ovary, has absolutely no effect whatever on that organ.
A simple ligature of each Fallopian tube would effectually and permanently sterilise, without in any way whatever altering or changing the organs concerned, or the emotions, habits, disposition, or life of the person operated on.
The Fallopian tubes are two in number, attached to the upper angles of the uterus, and communicating therewith.

Each is about five inches in length, and trumpet-shaped at its extremity, which floats free in the pelvic cavity.
Attached to the margin of this trumpet-shaped extremity, is a number of tentacle-like fringes, the function of which is to embrace the portion of the ovary, where an ovum has matured during or immediately after menstruation.
At all other times these tubes are practically unattached to the ovaries.

Ova may and do mature on the surface of the ovaries, but do not always pass into the Fallopian tubes; being almost microscopic, they are disintegrated and reabsorbed.

If they do pass into a tube they are lost or fertilized as the case may be.
It can be seen that the function and vitality of the ovaries are in no way affected by the tubes.

The ovarian function goes on, whether the tubes perform their function of conveyance or not, and if this function can be destroyed, life-long sterility is assured.
