In , Sense about Science launched the Ask for Evidence campaign. A huge number of studies from across the world contribute to a vast evidence base on this topic. This facilitates optimal development spermatogenesis of the spermatozoa.

At the onset of puberty, increased levels of lutenizing hormone LH; a pituitary gonadotroph induce the testes to produce testosterone, which will lead to the maturation of the spermatozoa. Once mature, the spermatozoa migrate from the testes to the epididymis a compartment attached to each testis where they are stored. One end of the epididymis tapers into the ductus deferens, the tube through which the mature sperm that are stored in the epididymis will pass to leave the scrotum.

The ductus deferens leads into the prostatic urethra. During ejaculation, the sperm will be drawn out of the epididymis through the ductus deferens and will combine with semen, secreted by the prostate gland, in the prostate urethra before being expelled.

Evaluation of a Male's Soundness for Breeding. Successful breeding on the part of the male is dependent upon 1 his physical ability to copulate, 2 his drive to copulate i.

If any of these factors is compromised, then the likelihood of successful conception within the bitch may be greatly diminished or completely inhibited.

From a physical standpoint, proper nutrition and conditioning exercise are essential for assuring optimal performance and fertility in the male. Additionally, since breed-specific genetic disorders may not only impact upon the quality-of-life of future offspring but also compromise breeding performance of the male, males intended for breeding should receive a thorough physical examination to evaluate orthopedic, neurologic, endocrinologic, and genital systems prior to breeding.

In regard to semen quality, optimum fertility is not necessarily a factor of age of the dog, but appears to be more dependent on the stage of the sperm within the ejaculate i. Quality of the semen, therefore, is often more affected by factors other than age including degree of arousal, frequency of ejaculation, collection technique and sample handling. Since frequent ejaculation daily collection of semen for 5 to 7 days can cause a reduction in sperm output, studs in high demand may experience less than optimal fertility at certain times throughout their reproductive years.

For this reason, it is recommended that sperm from valuable studs be collected and cryopreserved in sufficient quantities early in the male's career to ensure future availability.

To this end, collection of semen on an "every other day" basis typically allows time for replenishment of sperm reserves. Reproductive physiology and endocrinology of the dog. WB Saunders, , p. In the normal reproductive male, sperm production is directly related to testicular size. Sperm are stored in the extragonadal compartments of the epididymis and the ductus deferens. The amount of reserved sperm will depend on the frequency and interludes between ejaculations.

Total sperm counts in a sexually rested male encompass sperm reserves plus daily sperm produced by the testes. Sperm reserves are reportedly depleted by once per day ejaculation for 5 to 7 days. Therefore, once reserves are depleted, total sperm number will be represented only by the daily production of sperm by the testes. Collection of Semen for Artificial Insemination. Typically, the device consists of a rubber collecting cone attached to a plastic centrifuge tube.
