So much regarding the female part of the meeting of the ovum and the sperm.  The male part of this mutual act is as follows: 

The sperm, or spermatozoa, originate in the testicles.  Each sperm is an individual entity and several thousands of them are produced and in readiness for use, at each meeting of the male and female generative organs; and if any one of the countless number comes in contact with the unfertilized ovum in the womb, conception is liable to result.

These sperms are so small that they are not visible to the naked eye, but they are readily seen by the use of a microscope.  In shape they much resemble tad-poles in their earliest stages.

At the base of the penis, well up in the man’s body, there is a large gland which surrounds the penis like a thick ring, and which is called the prostate gland.  It secretes a mucous fluid which looks much like, and is about the consistency of the white of an egg.  Close to this gland, and almost a part of it, is a sack, or pocket, into which the mucous secretion from the prostate gland is poured, and where it is kept, ready for use, in performing its part of the germinal act.

Now it is the business of this mucous fluid, which comes from the prostate gland, to form a “carrying medium” for the spermatozoa which originate in the testicles.  There are small ducts leading from the testicles into the pocket which contains the prostate fluid.  These are known as the seminal ducts, and through them the spermatozoa pass from the testicles into the prostate pocket.  Here they mingle with the prostate fluid, in which they can move about freely, and by means of which they can be carried wherever this fluid goes.  The combination of prostate fluid and spermatozoa is called “semen.”

Seen under a microscope, a single drop of semen reveals a multitude of spermatozoa swimming about in the prostate-carrying medium.  It is in this form that the vitalizing male element meets the female infertile ovum.  This mass of live and moving germs is poured all around and about the region in which the ovum lies waiting to be fertilized, and every one of them seems to be “rushing about like mad” to find what it is sent to do, namely, to meet and fertilize the ovum.  The manner of depositing the semen where it can come in contact with the ovum is as follows: 

In order that this mingling of the male and female sources of life may be possible, it is necessary that there be a union of the male and the female generative organs.  For such meeting, the penis is filled with blood, all its blood vessels being distended to their utmost capacity, till the organ becomes stout and hard, and several times its dormant size, as has been already told.  In this condition it is able to penetrate, to its utmost depths, the vaginal passage of the female, which is of a nature to perfectly contain the male organ in this enlarged and rigid condition.
