Special Comment :
Final Impression- ASTHENOTERATOZOOSPERMIA
1. Terminology used in final impression is on the basis of total ejaculate concentration, motility & morphology. Additional parameter reported needs to be evaluated independently by the physician.
2. Impression based on 5th percentile value, however, 75th percentile value may be optimum and treatment plan may be suitably
decided by the physician.
3. 75th percentile value was decided optimum instead of 90th percentile by our clinical database and international opinion - to avoid too large an indeterminate group.
CASA: Computerised semen analysis is done with sperm class analyzer (http://www.spermclassanalyzer.com/) which provides fast, accurate & objectively repeatable results. This sophisticated software reports concentration, motility, morphology, vitality & DNA Fragmentation Index with unmatched accuracy with inbuilt QC/ QA checks.
Useful information:
Percentile value represents a range where the upper and lower reference limits (obtained by high quality reference data - WHO 5th manual and Asian Journal of Andrology 2010) define threshold levels of minimum and optimal numbers. Statistically, if the threshold levels are below 5th percentile pregnancy possibilities are extremely low and similarly if the levels are above 75th percentile pregnancy possibilities reach near normal population levels. The reporting format (first in India) ensures planning of cost effective solutions for male fertility problems.
Note: CASA - Semen Analysis is a guide to fertility and facilitates planning management. The report needs to be interpreted by the treating physician with corresponding clinical factors and is not a proof of fertility.

Recent Andrological advances: Advanced Andrology tests: Our advanced Andrology laboratory performs the following unique tests for the first time in India, to aid in specific management of Male Fertility problems:
1. DNA fragmentation index assessment for internal sperm defects - DFI
2. Sperm Functional Integrity assessment - SFI
3. Reactive Oxygen Species estimation - ROS
The following tests will be introduced shortly:
1. Sperm Developmental Defect assessment – SDD
2. Biological Fertility Assessment (Men) - Spermatogenesis, Spermiogenesis & Functional fertility assessment - BFA
(BFA is a comprehensive test which can predict fertility and identify the site of problems in men) – Contact your doctor or our lab for specific information.

SPERM FUNCTIONAL INTEGRITY ASSESMENT - SFI
Flagellar Integrity - Hypo Osmotic Swelling 41%
Osmotic Swelling Test
Normal : > 55 % spermatozoa with tail coiling
Significance : This test is a good index of healthy spermatozoa.
Clinical Relevance : Decrease in HOS positive reaction indicates loss of viability hence may be an indication of degenerative changes occurring
Spermiation defects - Acrosome Reaction after Ionophore Challenge 04%
ARIC Test
Normal : > 15 % spermatozoa with halos having mean diameter of 10 m
Subnormal : > 10-15 % spermatozoa with halos having mean diameter of 10 m
Abnormal :
Significance : This test evaluates the functional status of sperm acrosome and is
a good indicator of sperm’s ability to penetrate the oocyte.
Clinical Relevance : Decrease in Acrosome positive reaction indicate the
Possibility of low or nil fertilization.
Seminal Vesicle marker - Zinc concentration NA
Zinc concentration Test
Normal : 2.4 μmoL per ejaculate
Significance : The function of the accessory gland is assessed by the content of Zinc and
Zinc has been found to be critical to spermatogenesis
Clinical Relevance : Lower concentrations imply abnormal function of the accessory gland
High zinc concentrations have been reported to depress oxygen uptake in the sperm celL.
