A routine semen analysis should include: physical characteristics of semen (color, odor, pH, viscosity and liquefaction), volume, concentration, morphology and sperm motility and progression. To provide a correct result it is necessary to perform at least two, preferably three, separate seminal analyses with an interval between them of seven ...
The mucus is aspirated from cervical canal and spread on a glass slide. Smear from posterior fornix is used as control. 10-50 motile sperms per high power field are considered normal. Rotatory or shaky motion of sperms indicates presence of antispermal antibody. Cervical mucus is examined for quality, viscosity and fern test. [1]
How long the man has abstained prior to providing a semen sample correlates with the results of semen analysis and also with success rates in assisted reproductive technology (ART). Both a too short period of time since last ejaculation and a too long one reduce semen quality. A period of time of less than one day reduces sperm count by at ...
During the course of the video, the subject's semi-erect penis produces a drop of pre-ejaculate (also known as preseminal fluid, Cowper's fluid, or "pre-cum"); this is the typical amount produced at one time by this subject during arousal. A more thorough demonstration of the viscosity of this fluid can be seen here.
Higher repeatability: Since sperm count, morphology and motility of semen samples fluctuate within a short period of time, results of analysis are less repeatable. SCSA has a repeatability of 0.98-0.99 in clinical settings. Unless disruption is made by different lifestyles or medical intervention, experimental results are reproducible. [9] [4] [13]
When a semen analysis does indicate abnormal results, lifestyle factors recommendations prior to a new semen sample include a nutritional diet, as well as limitations on smoking and alcohol use. A cold bath and removal of tight-fitted underwear apparel may also be recommended within the month prior to re-examination.
Semen sample obtaining is the first step in spermiogram. The optimal sexual abstinence for semen sample obtaining is of 2–7 days. The first way to obtain the semen sample is through masturbation, and the best place to obtain it is in the same clinic, as this way temperature changes during transport can be avoided, which can be lethal for some ...
However, treatments are available for individuals experiencing pain/discomfort, fertility problems, [14] "symptoms of low testosterone levels", and unusual results from semen analysis. [15] Treatments include medication to address pain, surgery (microscopic and laparoscopic varicocelectomy), and embolization. [ 14 ]
