Clinical Presentations and Semen Characteristics of Men Attending the Secondary Referral Infertility Clinic at Mumbai, India.

BACKGROUND: Limited information is available on the aetiology and semen profiles of male infertility in Indian population. AIM: The aim of this study is to study the clinical and semen characteristics of men attending the infertility clinic and also to understand the impact of World Health Organization (WHO) 2010 reference values on the diagnosis of male infertility. SETTING AND DESIGN: A retrospective study evaluating the medical case records (January 2005 to December 2015, [n = 1906]) of men attending infertility clinic in Mumbai, India. MATERIALS AND METHODS: The aetiology was classified based on the andrology evaluation and other investigations. Semen profiles were compared during the years 2005-2010 and 2011-2015 using WHO 1999 and WHO 2010 criteria, respectively. STATISTICAL ANALYSIS: The Chi-square and Mann-Whitney U tests were performed using Open Source Epidemiological software and Social science calculators. RESULTS: The aetiology of male infertility was determined in 62% of the men; while the cause remained undetermined in 38%. Varicocele (25%), urogenital infections (10%), sexual dysfunctions (8%) and vas aplasia (8%) were identified as major aetiologies in our cohort. Men with sexual dysfunctions and vas aplasia were significantly higher during the years 2011-2015 as compared to 2005-2010. Men having normozoospermia (10%) and azoospermia (3%) were increased, whereas those having oligoasthenozoospermia (17%) were reduced in 2011-2015 as compared to 2005-2010. According to WHO 1999 criteria , 12-15% of men showed abnormal semen profiles. The semen parameters of these men became normal on using WHO 2010 reference values. CONCLUSIONS: Varicocele is the most common aetiology in infertile men. Idiopathic infertility was seen in a higher proportion among the infertile men.

Menstrual pad, a cervical cancer screening tool, a population-based study in rural India.

In the rural areas of India, women generally use a piece of old cloth as a menstrual device. The aim of this study was to detect human papilloma virus (HPV) from menstrual blood on the menstrual pad and assess whether this could be a useful screening tool for cervical cancer. In Jamkhed area of rural Maharashtra, (population A), we collected menstrual pads from women who provided consent in the 30-50 year age group. The women who had provided menstrual pads underwent HC2 testing. We standardized the method for extracting DNA by PCR from the menstrual pad. The women who tested HPV positive, on the basis of HC2/PCR testing, underwent colposcopy. In the rural population of Pune area of Maharashtra state (population B), menstrual pads were collected. HPV was tested using the PCR method. HPV-positive women and a few HPV-negative women, selected randomly, underwent colposcopy and HC2 testing. In population A, 164 women provided their used menstrual pads and also underwent an HC2 screening test. Of these, six (3.2%) cases were reported as HPV positive. In population B, 365 women provided their used menstrual pads for HPV testing, of which 18 (4.9%) cases were diagnosed as HPV positive. The women who tested HPV positive, on the basis of PCR testing, and 10% randomly selected HPV-negative cases (37) and 18 women who voluntary requested testing underwent colposcopy and HC2 testing. The sensitivity of menstrual pad HPV testing compared with gold standard HC2 testing was 83% [95% confidence interval (CI): 0.47-0.97], 67% (95% CI: 0.30-0.91) and specificity was 99% (95% CI: 0.96-0.99), 88% (95% CI: 0.77-0.94) in population A and population B, respectively. The sensitivity of diagnosing CIN lesion was 83% (95% CI: 0.44-0.97) and specificity was 95% (95% CI: 0.91-0.97). On the basis of the sensitivity and specificity results, and the completely noninvasive, simple and convenient method of detecting HPV, menstrual pad might be considered a cervical cancer screening tool in rural Indian women.

Elastase: a predictive marker of inflammation and/or infection.

The present study was undertaken to estimate elastase in biological fluids and assess its usefulness as an indicator of inflammation/infection. Elastase was measured in seminal plasma, serum, urine, and cervical specimens using a specific substrate and was expressed in arbitrary units (AU). It was found to be stable over a period of 3 weeks. The intra- and interassay variation of elastase assay was between 2.3 to 6.8% and 7.3 to 9.9%, respectively. The assay was validated by comparing it with other methods that are available for the detection of infections. Sensitivity of the assay indicating inflammation/infection in these samples varied between 70.9 to 87.3%. The results obtained suggest that the presence of elastase in specimens may be used as a nonspecific indicator and could be used to screen inflammation/infection in a limited resource setting.
