SEMEN ANALYSIS

COLLECTION OF SEMEN

• Semen for examination is collected after at least 3days of abstinence from intercourse.
• At least 30mints is given for liquefaction.
• After collection microscopic examination is completed between 1-2 hrs of collection.

NORMAL VOLUE OF THE SPERM

• Formula of sperm cont=(sperm counted in 4 squares *10*20*1000)/4
• Normal sperm count : 40 - 160 millions/ml

ABNORMAL FORMS OF SPERM

• Giant head sperm
• Pin head sperm
• Immature tail sperm
• Double tail sperm
• Double head sperm
• Amorphous form of sperm

DISORDERS

• Azoospermia :~
• If spermatozoa is completely absent in the semen than that condition is called azoospermia
• Oligospermia:~
• Oligospermia denote to low sperm count often with decreased motility

PHYSICAL EXAMINATION OF SEMEN

PHYSICAL EXAMINATION OF SPERM

• Volume
• Consistency or liquefaction
• Ph
• Viscosity

VOLUME

• The normal volume average from 2-5ml .
• The volume does not vary significantly with the period of abstinence.

CONSISTENCY OR LIQUEFACATION

• Observer the consistency of the semen at the time of receiving the sample & note the time taken for the specimen to liquefy.
• Normally it liquefies between 30-40 minutes

PH OF THE SEMEN

• Ph normal range from 7.0-7.7

VISCOSITY

• Normal semen is slightly viscous form
• Abnormal semen is very much viscous
• In other conditions it may be watery.
