Etiological spectrum and contributing factors of male infertility among Pakistani men.
Article in Pakistan journal of medical sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background & Objective: Infertility is a significant concern worldwide, affecting millions of couples, yet often under-recognized. In Pakistan, approximately 22% of couples experience infertility, with male factors contributing in 20-25% of cases. Despite advances in reproductive medicine, male infertility remains poorly understood, often requiring specialized interventions. This study aimed to investigate the underlying causes and contributing factors of male infertility in Pakistani men presenting at a specialized infertility unit in Karachi, Pakistan. Methodology: A retrospective observational study was conducted at the Baqai Institute of Development Sciences (BIRDS), Baqai Medical University, Karachi, from 2015 to 2022. The study included all male patients of reproductive age (18-50 years) who were married, cohabiting and attempting to conceive for over a year without success. For the present analysis, data from couples in whom male factors were identified as the predominant cause of infertility were included. Clinical characteristics, demographic variables, lifestyle habits, comorbid conditions and relevant laboratory parameters were retrieved from medical records. Data were entered and analyzed using SPSS Statistics, version 25.0. Results: A total of 809 infertile males aged 18-50 years were evaluated. Primary infertility was more common (79.4%) compared to secondary infertility (20.6%). Among the study population, notable comorbidities included diabetes (41.1%) and hypertension (21.3%). Lifestyle factors were also prevalent, with 34.2% reporting smoking, 39.7% using tobacco and 34.7% having a history of testicular surgery. Semen analysis revealed azoospermia in 16.7% of cases, asthenoteratozoospermia in 8.3% and normozoospermia in only 0.4%. A considerable number of participants had a history of sexually transmitted diseases (STDs) and varicocele was identified in 19.4% of cases. Additionally, a family history of infertility was present in 21.9% of individuals. Conclusion: Male infertility in Pakistan is influenced by a complex interplay of metabolic, infectious and lifestyle factors. Diabetes, sexually transmitted infections and prior testicular surgeries were key contributors. These findings call for greater awareness and accessible fertility services, along with multicenter research to guide health policies and optimize management in resource-limited settings.
