Quest for An Ideal, Simple and Cost-Effective Stain for Morphological Assessment of Sperms.

BACKGROUND
Recent alarming trends of a substantial rise in the number of cases of infertility with as many as 30-40% being attributed to male-factor associated causes have created a need for further studies and advancements in semen analysis. Despite the focus on semen analysis over the years, assessment of sperm morphology has not been given due importance although it is a simple, standard and baseline diagnostic modality. It can be used to predict the need and outcome of Artificial Reproductive Techniques such as Invitro Fertilization, Gamete Intra Fallopian Tube Transfer and Intra Cytoplasmic Sperm Injection.


AIM
To find the ideal, simple and cost-effective basic stain for assessment of sperm morphology in a rural tertiary care set- up where advanced equipment for assessment of sperm morphometry are inaccessible.


MATERIALS AND METHODS
An updated way of determining sperm shape is called the Kruger's strict morphology method. Keeping this as the standard criterion, we studied semen samples of 62 healthy male subjects using four basic staining techniques and the consensus of four independent observers was tabulated.


RESULTS
We found that Haematoxylin and Eosin stain was the best stain for assessment of sperm head morphology. Rapid Papanicolau stain was the most ideal, simple and cost-effective stain for overall assessment of sperm morphology.


CONCLUSION
Sperm morphology assessment remains the baseline necessity for the diagnosis and management of male factor associated infertility when advanced techniques are unavailable, inaccessible or unaffordable.
