Penis in horse vagina

Temperature The production of sperm might also be affected by temperature, so nature has provided the stallion with thermal regulatory features designed to maintain a relatively constant temperature within the testes. The testes are suspended within the scrotum by the spermatic cord and associated cremaster muscle. During cold weather, the muscles involved with both the scrotum and the spermatic cord contract, drawing the testes closer to the body for additional warmth.

At the same time, during episodes of hot weather, the scrotum stretches and the numerous sweat glands on the skin help regulate the temperature through the evaporation of perspiration. Also involved in the thermal regulation process is heat transfer between blood from the arteries entering the testes and venous blood leaving them.

Proper regulation of heat horse the testes has a profound effect on sperm production. This becomes significant when one realizes that the total length of time for the production and maturation of spermatozoa totals approximately 65 days. First, a look at the route the sperm will take. From the tail of the epididymis, where the majority of sperm is stored, it will be delivered to the deferent duct, which vagina a continuation of the epididymal duct and runs from the tail of the epididymis through the spermatic cord to the pelvic urethra.

As the deferent duct approaches the pelvic urethra, it widens into a structure termed the ampulla of the deferent tranny for free.com. The ampulla is about 18 vagina in diameter, compared to 4 to 5 millimeters for the deferent duct. During ejaculation, sperm is moved penis through the ducts and into the urethra by muscular contractions. Along the route through the ducts that the sperm will travel are the two vesicular glands, which are elongated, hollow pouches about 15 to 20 centimeters long and 5 centimeters in diameter.

Fluid secreted by the vesicular glands contributes a major portion of the seminal plasma in an ejaculate. Next along the route is the prostrate gland, which is a single, firm, nodular gland with two narrow lobes connected by a thin, transverse isthmus. The secretion horse the prostate gland is thin and watery and likely helps to cleanse the urethra during ejaculation.

Penis also contributes to the seminal plasma.

Next we come to the two bulbourethral glands free porn with mom lie on either side of horse pelvic urethra near the ischial arch. Their secretion also contributes to the seminal plasma. The role of seminal plasma is not fully understood.

It is believed that, in addition to serving vagina a means to transport sperm through the male tract, it also contains buffers, nutrients, and stabilizing factors for spermatozoa. The vesicular glands, prostate gland, and bulbourethral glands are termed the accessory sex glands. They contribute most of the fluid to the ejaculate, but are not essential for normal fertility of the sperm. Their ability to function normally is dependent on the presence of testosterone in the peripheral blood.

As the sperm completes its journey through the penis ducts, fortified along the way with seminal plasma, it ultimately arrives at the urethra, a long mucous tube that extends from the bladder to the free end of the penis.

The urethra serves as a joint excretory canal for both urine and semen. Semen is the term used to describe the whitish fluid of the male reproductive tract consisting of spermatozoa suspended in secretions of the accessory glands. The pelvic portion of the urethra is overlaid by a thick striated muscle that contracts vigorously during ejaculation. The penile urethra is surrounded by the corpus spongiosum, which is an area of cavernous, erectile tissue. The penis is the male organ of copulation and consists of three parts.

They are the root, which attaches the penis to the pelvis via two strong ligaments and a pair of muscles; the body or shaft, which is the main portion of the penis; and the glans penis, which is the enlarged free end of the penis. The major portion of the penis is formed by the corpus cavernosum penis. It is spongy, erectile tissue that becomes engorged with blood during erection.

The corpus spongiosum is a small area of spongy erectile tissue that immediately surrounds the urethra. It also becomes engorged with blood during erection. The glans penis is filled with a multitude of nerve endings and becomes engorged and erect during sexual excitement.

These are some of the commonest advantages to each model that we and others have noted:. Many farms and semen collection centers use a sterile liner in the artificial vagina. This liner is usually made of a thin plastic of some sort, and is especially useful if one is collecting semen from different stallions, as it pretty well eliminates any chance of cross-contamination of any kind, either bacterial or seminal.

Details of this procedure horse be found in a paper available at www3. You might still need to try to limit the amount of tumescence to the initial level of flowering before stimulating thrusting, since ejaculation is sometimes impeded once the full flowering has occurred.

You might even be able to reliably use an artificial vagina if you do ground collection in his stall or a wash rack without a mare, dummy, or the breeding area to heighten his arousal.
