Objective: To study the patterns and distribution of various abnormal semen parameters in infertile males. Study Design: Cross sectional study. Place and Duration of Study: Department of Pathology, Combined Military Hospital, Karachi, from Nov 2019 to Oct 2020. Methodology: The study included 364 patients who presented with primary and secondary infertility. Consecutive convenient sampling was done. Semen analysis was performed using World Health Organization latest guidelines. Samples were categorized as normospermia, azoospermia, oligospermia, asthenozoospermia and necrospermia. Results: The study comprised of 364 samples of infertile males. Normal sperm count was observed in 317 (87%) males, azoospermia in 28 (7.6%) and oligospermia in 19 (5.2%) males. Low ejaculated volume and higher non-motile sperms were noted in oligospermia samples in comparison with normospermia samples. Asthenozoospermia was observed in 102 (28%) and oligoasthenospermia was noted in 15 (4.1%) samples. Conclusion: Good quality semen analysis is a corner stone to diagnose the cause of male infertility.Sperm concentration and motility are the important markers of normal male reproductive system and are related to each other.

IntroductionBirth rates have been declining in many advanced societies including Singapore. We designed two interventions with vastly different resource requirements, which include fertility education, personalised fertility information and a behavioural change component targeting modifiable psychological constructs to modify fertility awareness and childbearing intentions. We aim to evaluate the effect of these two interventions on knowledge, attitudes and practice around childbearing compared with a control group among young married couples in Singapore and understand the implementation factors in the setting of an effectiveness-implementation hybrid type 1 three-arm randomised trial.Methods and analysisWe will randomise 1200 young married couples to no intervention (control), Fertility Health Screening group (FHS) or Fertility Awareness Tools (FAT) in a 7:5:5 ratio. Couples in FHS will undergo an anti-Mullerian hormone test and semen analysis, a doctor’s consultation to explain the results and standardised reproductive counselling by a trained nurse. Couples in FAT will watch a standardised video, complete an adapted fertility status awareness (FertiSTAT) tool and receive an educational brochure. The attitudes, fertility knowledge and efforts to achieve pregnancy of all couples will be assessed at baseline and 6 months post-randomisation. Birth statistics will be tracked using administrative records at 2 and 3 years. The primary outcome is the change in the woman’s self-reported intended age at first birth between baseline and 6 months post-randomisation. In addition, implementation outcomes and cost-effectiveness of the two interventions will be assessed.Ethics and disseminationThis study has been reviewed and approved by the Centralized Institutional Review Board of SingHealth (2019/2095). Study results will be reported to the study funder and there are plans to disseminate them in scientific conferences and publications, where authorship will be determined by the International Committee of Medical Journal Editors guidelines.Trial registration numberNCT04647136; ClinicalTrails.gov Identifier.

The aim of the study was to determine the morphological and morphometric characteristics of the vicuña sperm (Vicugna vicugna), looking for possible subpopulations in its structure. Semen was collected by electroejaculation method from three adult male vicuñas weighing 50.33 ± 2.52 kg, once per animal. The volume, color and concentration, sperm morphology and morphometry were determined. The samples for the analysis of sperm morphology and morphometry were stained with Hemacolor®, and analyzed using the CASA-Morph, Integrated Semen Analysis System (ISAS®v1). Five forms of the vicuña sperm head were distinguished: normal, piriform, long, short and rounded. The morphometric parameters determined were the length, width, area, perimeter, ellipticity, elongation, regularity and rugosity of the vicuña sperm head, percentage of acrosome, head gray level, as well as the width, area, distance and angle of insertion of midpiece of the sperm. In relation to morphology, significant differences (P <0.05) were found in the percentage distribution of head shapes, with the normal shape (55.7%) being the majority and different from the other shapes. Significant differences (P <0.05) were found between animals in the morphometric variables of head, percentage of acrosome, ellipticity, rugosity, elongation and gray level; while the variables of the midpiece and regularity did not show differences (P> 0.05). The morphometric variables were distributed in four main components (PCA) called elongation, area, circularity and midpiece width, which explained 84.59% of the total variance. The cluster analysis determined five subpopulations (SP): SP1 grouped small cells of low length, width and area (18.8%); SP2 of sperm of large size, both in area and width of the head (17.38%); SP3 of rounded cells with high values of percentage of acrosome and head gray level (24.04%); SP4 of spermatozoa of intermediate size and elongated, with greater ellipticities and elongation (23.61%); and SP5 of cells of intermediate size and short, with low values of area and length (16.71%).

Objective: To evaluate the frequency of semen parameters in male partners of in sub-fertile couples. Study Design: Cross-sectional study. Setting: Department of Gynaecology, Bakhtawar Ameen Hospital, Multan. Period: July 2019 to July 2020. Material & Methods: Infertile couples from at least 12 months were selected for study. A team of Gynaecologist, andrologist and endocrinologist assessed the couples. In male partner, general physical examination, endocrine factor, genetic assessment, accessory gland infection and testicular dysfunction were evaluated. Semen sample was sent to laboratory for semen analysis. Results: In a total of 169 sub-fertile couples, the mean age of male and female partner were 37.98±4.54 years and 32.51±3.78 years respectively. Mean duration since marriage was 5.17±4.51 years. Abnormal semen parameters such as azoospermia, oilgo-azoospermia, asthenozoospermia, teratozoospermia and aspermia were noted 21 (12.4%), 26 (15.4%), 48 (28.4%), 18 (10.7%) and 10 (5.9%) subjects respectively. There were 46 (27.2%) subjects with normal semen parameters. Conclusion: Most of the male sub-fertile subjects had asthenozoospermia. More than one fourth of the subjects had normal semen parameters.

Introduction: Varicocele is among the most frequently encountered, surgically correctable causes of male infertility. Since varicocele is a primary abnormality of testicular vessels, a thorough understanding of haemodynamic changes in the microcirculation of varicocele testis is needed. Objectives: To estimate changes in the microcirculation of varicocele testis and correlate them with symptomatic and semen parameters changes before and after varicocelectomy. Material and methods: This prospective, observational study includes 47 patients of age group 18–40 years who underwent microsurgical varicocelectomy during June 2016 to April 2018 at a tertiary medical institute. Testicular haemodynamic was evaluated using a colour spectral doppler study (PSV-Peak systolic velocity/ESV-End diastolic velocity/RI-Resistive index/PI-Pulsatility index). Semen analysis parameters and testicular blood flow were compared with pre-operative values. Results: RI in the capsular artery of varicocele affected testis, which was 0.61 ± 0.11 (mean ± SD), significantly reduced to 0.56 ± 0.09 (mean ± SD) in post-operative follow-up, indicating improved perfusion. Pre-operative sperm density was noted to be 15.94 ± 7.88 (mean ± SD), which improved to 28.41 ± 10.99, Progressive sperm motility from 33.81 ± 10.88 to 38.32 ± 9.21 and morphology from 36.13 ± 10.68 to 41.43 ± 9.29 on 6-month follow-ups ( p < 0.05). Conclusion: Varicocele testis is associated with altered testicular haemodynamic, which insults spermatogenesis. Microsurgical varicocelectomy with testicular artery and lymphatic preservation leads to correction of this altered haemodynamic state and improves the testicular microcirculation.
