Abusing AAS is starting to become a public health concern that implies the need to implement educational programmes, which will educate and warn adolescents and mentors about the negative side effects of AAS abuse on the health of users.
The long arm of the Y chromosome contains nonoverlapping regions termed azoospermia factor (AZF) with great influence on male fertility. Microdeletions at these regions minimise the males' ability to father offsprings. In this preliminary study, we attempted to screen the presence or absence of twenty Y chromosome's sequence-tagged sites (STS) associated with fertility in infertile and Down syndrome (DS) males. Genomic DNA from 35 fertile, 74 infertile and 22 karyotyped DS males was extracted and amplified in multiplex polymerase chain reaction (PCR) containing 20 primer pairs that amplify Y-specific STS that cover functional regions associated with AZF and spermatogenesis-related genes. Our results indicated the integrity of the Y chromosome at the 20 fertility markers for both the fertile and Down syndrome males. However, the results of the infertile males showed the presence of microdeletions at these Y-specific STS. Three samples showed Y chromosome microdeletion when blood and seminal fluid genomic DNA were assayed, while two samples showed microdeletion only when seminal fluid genomic DNA was assayed. The current study demonstrated that the molecular genetic aspect of infertility should be given proper attention when dealing with infertility cases. Furthermore, our results indicate the importance of genetic counselling in managing infertility cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
