Semen analysis as an integral part of infertility investigations is taken as a surrogate measure for male fecundity in clinical andrology, male fertility, and pregnancy risk assessments. Clearly, laboratory seminology is still very much in its infancy. In as much as the creation of a conventional semen profile will always represent the foundations of male fertility evaluation, the 5th edition of the World Health Organization WHO manual is a definitive statement on how such assessments should be carried out and how the quality should be controlled. The methodology used in the assessment of the usual variables in semen analysis is described, as are many of the less common, but very valuable, sperm function tests. Sperm function testing is used to determine if the sperm have the biologic capacity to perform the tasks necessary to reach and fertilize ova and ultimately result in live births.

As sperm travel through the male reproductive tract, they are bathed in fluids produced and secreted by the various tubules and glands of the reproductive system. After emerging from the testes, sperm are stored in the epididymisin which secretions of potassium, sodium, and glycerylphosphorylcholine an energy source for sperm are contributed to the sperm cells. Sperm mature in the epididymis. They then pass through a long tube, called the ductus deferensor vas deferens, to another storage area, the ampulla.
The ampulla secretes a yellowish fluid, ergothioneine, a substance that reduces removes oxygen from chemical compoundsand the ampulla also secretes fructose, a sugar that nourishes the sperm. Seminal fluid semen sperm the process of ejaculationliquids from the prostate gland and seminal vesicles are added, which help dilute the concentration of sperm and provide a suitable environment for them. The prostate gland contributes about 30 percent of the seminal fluid; the constituents of its secretions are mainly citric acidacid phosphatase, calciumsodiumzincpotassiumprotein -splitting enzymes, and fibrolysin an enzyme that reduces blood and California nurse strikes fibres.
A small amount of fluid is secreted by the bulbourethral and urethral glands ; this is a thick, clear, lubricating protein commonly known as mucus. Essential to sperm motility self-movement are small quantities of potassium and magnesiumthe presence of adequate amounts of oxygen in the plasma, proper temperature, and a slightly alkaline pH of 7 to 7. Sulfate chemicals in semen help prevent the sperm cells from swelling; and fructose is the main nutrient to sperm cells. The total volume of semen Thick girls squirting each ejaculation of a human male averages between 2 and 5 ml 0.
