Seminal fluid analysis Seminal fluid analysis What is semen? Semen is the fluid formed at ejaculation. Made of secretions of all the accessory glands of the male genital tract and testicular sperm component Semen quality is maintained by all the accessory glands Seminal fluid analysis Formation Semen is formed by the four fractions of the testes Epididymis, seinal vesicles, prostate gland and bulbourethral glands Each fraction differs and mixing during ejaculation is essential for normal semen Seminal fluid analysis Purpose of the test Semen analysis mainly measures the amount of semen a man produces and determines the number and quality of sperm One of the routine tests done to determine male infertiliy To determine the effectiveness of vasoctomy To assess suitability of semen for artificial insemination Forensic and medico legal cases requires semen analysis in sex crimes Seminal fluid analysis Sample collection Samples are collected after a period of abstinence of 2 days If not false results may appear Complete sample collection after ejaculation is essential If not false results may appear Sample should be collected in to pre warmed sterile, non-toxic, wide mouth container Should be tested within 1-2 hours Many methods are in practice Seminal fluid analysis Seminal fluid analysis Following parameters are routinely checked Volume, Viscocity, pH, Sperm count, Motility and morphology Volume Normal volume is 2-5 ml. A low volume is generally a result of problem with any of the four glands secretions and is associated with infertiligy Color and viscocity Normal semen has a gray-white /yellow color and has musty odor. Viscosity refers to the consistency of the fluid and is direct relation with liquefection. Normal semen should be drawn in to pipet and forms discrete droplets that are not clumped. Viscosity can be reported as low (watery) to high (gel like) pH Normal pH range is 7.2-8.0 (increases with time) Abnormal pH indicates abnormal secretion of any of the Four glands Seminal fluid analysis Microsocpic examination Concentration (count) This is the measurement of how many million sperms are present in 1 ml of the sample Various techniques are in practice Average sperm concentration is more than 60 million / ml (60-150 mil/ml) Counts lessthan 20 million are considered sub-fertile Azoospermia Oligozoospermia Polyzoospermia Total absence of Reduced number of Increased number of sperms in the sample sperms (
