Abstract
Abstract
Study question
Does the approach of sperm preparation technique plays any role in sperm DNA Integrity
Summary answer
Outcome of the semen sample is directly proportional to the choice of preparation technique. Microfluidics improves sperm selection and results in better sperm DNA integrity
What is known already
Microfluidic systems are promising tools for fluid manipulation that can noninvasively separate motile sperm with higher hydrodynamics profile from the lower ones. It also enables to manipulate micro swimmers as compared to the traditional methods that to without centrifugation .As it is already known that Semen analysis and preparation is one of the most important aspects in andrology and microfluidics can improve sperm analysis and selection, therefore increasing the ART success rates
Study design, size, duration
Comparative study from July 2019 to Dec 2021 in IVF unit of IKDRC Hospital .A total number of 900 patients were enrolled in the study and were randomized by using computer generated list then divided into two groups, Group A contains 460 samples and Group B having 440 samples.
Participants/materials, setting, methods
Group A (n = 460) sample was prepared by using Microfluidic sperm Sorting technique and Group B (n = 440) sample was prepared by conventional Swim up technique. Samples were analyzed according to WHO 2010 laboratory manual for examination and processing of human sperm, including all normozoospermic samples. Primary outcomes of the study was DNA Fragmentation index (DFI) and it was evaluated by using sperm chromatin dispersion (SCD) test and secondary outcomes was Progressive motility .
Main results and the role of chance
DNA fragmentation index is significantly lower in group A where Microfluidic Sperm Sorting technique (MFSS )is used than in group B where conventional swim up technique is use (10.06% vs 34.2%, p<0.0001) significant values implies that DNA integrity is better in group A than in group B and progressive motility was also found to be significantly higher in group A as compared to group B (57.6%vs16.9%, p <0.001).
Limitations, reasons for caution
As sample size was smaller, larger randomized control studies are needed to strengthen these results and all normal samples were used for the analysis and preparation , abnormal parameters were not involved .
Wider implications of the findings
According to our study the samples prepared by Microfluidic technique have higher DNA integrity than samples prepared by Swim up technique. Lower DNA Fragmentation index in microfluidics outcome indicates lower DNA damage. Choice of technique for the preparation of semen sample also plays a key role in better sperm selection.

Abstract
OBJECTIVE A preliminary opt-out screening study for HIV was conducted in a tertiary care hospital in India according to Center for Disease Control (CDC) guidelines. A total of 876 cases were screened for HIV during August 2007 to December 2007 using tests approved by the National AIDS Control Organization (NACO). RESULTS Data indicates that the prevalence of HIV in emergency and pre-surgical setting was 21 per thousand at the tertiary care center. Positivity rate in the pediatric population was 20.9 per thousand while in adults it was 21.4 per thousand. Most patients were totally unsuspected. Nearly 40000 patients seek admission annually to the emergency department alone. Thus nearly 700 to 800 patients may be missed every year if one does not resort to such a practice. CONCLUSION Since India has the second largest number of HIV cases in the world, opt-out screening program and testing in an emergency setting, as recommended by CDC, is extremely relevant. Logistics of implementation of this policy need to be worked out at a national level.
