	Beef Semen and MVE Semen Tanks
		Artificial insemination (A.I.) using frozen beef semen offers cattle producers an opportunity to breed their cows to bulls possessing far superior genetics than are available locally and do it at an affordable price.
		Using the top genetics available with frozen beef semen will allow you to select for traits to improve calving ease, weaning weight, yearling weight, maternal ability and carcass quality with a high degree of accuracy.
		And beef semen and frozen embryos stored in liquid nitrogen in one of our MVE semen tanks will last for years.

	Semen Analysis
		Normal semen is an admixture of spermatozoa suspended in secretions from the testis and epididymus which are mixed at the time of ejaculation with secretions from the prostate, seminal vesicles, and bulbourethral glands.
		The gold standard for the detection of all WBC populations in semen is immuno-cytology using monoclonal antibodies (23).
		Due to the variety of possible sperm and semen abnormalities, a comphrehensive approach using several tests is generally employed to assess the integrity of semen specimens.

	Semen
		Semen is the white/yellow fluid that comes out of the penis when a guy ejaculates.
		About 3% of the semen is made up of spermcells, 15-30% comes from the prostate and about 70% from the seminal vesicles.

		Semen has to be cultured for aerobic and anaerobic infection as well as Chlamydia and Mycoplasma.
		Absence of fructose, low semen volume, and failure of the semen to coagulate indicate either congenital absence of the vas deferens and seminal vesicles or obstruction of the ejaculatory duct.

	Can semen cure the blues? - Salon
		Semen is a nutritious medium that supports spermatozoa on their journey through a woman's plumbing.
		In fact, semen is a rich chemical brine, containing testosterone, estrogen and other hormones: prostaglandins (made in the prostate gland), as well as luteinizing hormone and follicle-stimulating hormone (both trigger ovulation).
		Scientists know that chemicals in semen are absorbed into a woman's bloodstream through the vagina.

	AI/Semen
		Semen can be collected and extended with reasonable fertility expected for the first 6-8 hours.
		Because the results of fresh-semen AI are acceptable, the challenge for research is to extend the life of the semen to enable insemination to be done beyond the day of collection.
		Cervical AI with frozen semen should only be done in sheep when attempts to penetrate the cervix have failed the semen is simply "dumped" at the farthest possible site.

	Semen (Site not responding. Last check: )
		Biologically speaking, the main purpose of semen is to help sperm survive their journey to a female's egg, where fertilization occurs.
		Besides sperm, semen is made of secretions from the seven lower urinary tract structures.
		Semen itself has high concentrations of potassium, zinc, citric acid, fructose, phosphorylcholine, spermine, free amino acids, prostaglandins and enzymes, which nourish and protect the sperm.

		The production of semen marks the beginning of puberty for boys — a time when the body begins to grow and develop rapidly — especially the sexual organs.
		Actual semen quantity differs among individuals and can also change for the same individual during different times of his life.
		Semen from a mature male is usually a milky or pearly-white color.

	Semen Collection from Dogs
		Semen is collected from dogs for breeding soundness exams, as well as for artificial insemination.
		Another indication for collecting semen is to obtain prostatic fluid for culture or cytology in cases of suspected prostatic disease.
		Semen can be collected from most males without the need for a teaser bitch, particularly if the male has had semen collected previously.

	Stallion Management - Semen Collection and Evaluation
		The most effective process of semen collection requires the stallion use an artificial vagina to collect a representative semen sample for either fertility evaluations or insemination.
		The gel-free portion of the semen sample is measured for volume and a small portion is set aside for motility and concentration studies.
		The small semen sample outside the incubator is quickly evaluated microscopically for motility and progressive (quality of movement) motility.

	Transported Semen - The Stallion Owner's Side
		We greeted the news that transported semen would be allowed for purebreds with cries of relief since it would enable us to breed our own mares to CMK stallions far away from us and we could offer our stallions to mare owners who could not send their mares to our farm.
		The down side of transported semen is the expense, both of the initial testing and equipment purchases and of the ongoing permit fees.
		It is recommended that at the start of each breeding season a 24 hour semen evaluation test be performed to be sure that the collection procedures are still working and that there have been no changes in the semen and its ability to survive transport.

	Semen acts as an anti-depressant - 26 June 2002 - New Scientist
		The study, which is bound to provoke controversy, showed that the women who were directly exposed to semen were less depressed.
		The researchers think this is because mood-altering hormones in semen are absorbed through the vagina.
		In this study, the always-use-condoms group were more depressed than the usually-use-condoms group, suggesting the discrepancy in the smaller study was a sampling error, he says.

	Frozen Semen
		If we assume that all dogs could have problems associated with their semen, by removing all the prostate and/or supportive fluids from the semen collection we can control and ensure that all semen processed will be as uniform as possible.
		The semen is then prepared with the different solutions that Clone developed specially for this, to preserve the semen and to eliminate the eventual damage the freezing might do to the sperm cells.
		Different countries have different rules for importing frozen semen and some countries also claim some blood work to be done on the stud dog when the semen is frozen so you must know this already at the time of the freezing.

	JackinQ&A — Questions About Semen & Ejaculation
		Semen is a mixture of many substances, and outside of water and saline solution, it's rare for anything put into the eye not to sting.
		Semen does contain protein, but the amount you ejaculate is negligible compared to the total amount your body takes in.
		Semen is composed of different fluids made in different parts of the reproductive system (see Science Corner article on Semen Production and Ejaculation), and these different components often have different qualities.

	Everything About Frozen Canine Semen Bank
		Dog breeders who plan to have their dog’s semen collected, frozen and stored should realize that a facility that states it can freeze canine semen does not necessarily have the ability to produce puppies after the semen is frozen.
		To become an A.K.C. approved center, a center must have the correct record keeping system and semen storage container; the center is not required to be capable of producing puppies with the frozen semen.
		However, the client is informed when the semen is being prepared that it’s quality is such that it will require a surgical insemination, and even then it may not create a pregnancy.

	FAQ's about Frozen Semen
		A: Once the semen is collected from the stallion, which is the same process as collecting for cooled transported semen or on farm AI (artificial insemination), it is evaluated to establish sperm concentration and motility levels.
		The semen is then mixed with a centrifugation extender, and the majority of the seminal plasma is removed by centrifugation.
		A: As long as the semen is not thawed, and is maintained in a liquid nitrogen storage tank, the working life is believed to be nearly unlimited.
