Abstract
Background: Azoospermia is one of the social problems affecting families/countries today in the whole world, which has resulted in an involuntary declining birth rate [1]. Worldwide, more than 70 million couples suffer from infertility, and it is estimated that azoospermia is found in up to 10 to 20 percent of the men who present to an infertility clinic [2]. Uganda is among the countries where male infertility is assumed to be a big challenge, with an estimated 5,000,000 people facing infertility, where 10 to 15% of the couples are unable to have children. Hence the current study aimed at establishing the risk factors associated with azoospermia among patients attending Ebenezer Clinical Laboratory, Kampala, Uganda.
Methods: A retrospective case-control study design was conducted on men who had visited the Microbiology Department for semen analysis from 1st January to 31st December 2015. Cases were azoospermic participants in the ECL database with no sperm cells in the ejaculate whereas controls were normozoospermic participants in the ECL database with normal sperm cells in the ejaculate. Systematic sampling was employed in the selection of respondents using their clinical records. The sample size was 204 (102 cases and 102 controls) clients, determined using a formula from the OpenEpi software package for Kelsey. The sample involved 102 cases and 102 with a ratio of cases to controls being 1:1. The study used a data abstraction structured questionnaire for data collection. Data was analyzed using descriptive statistics to generate frequencies and percentages. Chi-square test and logistic regression analyses were used to determine whether there was a significant association between risk factors and azoospermia with about 0.05 statistical significance.
Results: The study found out that tobacco use [AOR = 11.245, (CI 95% = 3.913 – 32.312), p = 0.000], marijuana use [AOR = 21.975, (CI 95% = 5.710 -44.571), p = 0.000], type of underwear [AOR = 9.366, (CI 95% = 4.360 – 19.9471), p = 0.000] were statistically significant factors associated with azoospermia among patients
Conclusions: Interventions should be focused on improving these factors, such as minimizing tobacco and marijuana usage among the populations, as well as sensitizing the males on the dangers of wearing tight underwear.
