Reciprocal translocation is closely associated with male infertility and recurrent miscarriages. Balanced reciprocal translocations associated with reproductive failures are predominantly observed on chromosome 1. Additionally, infertile male patients present a number of breakpoints throughout chromosome 1. A translocation breakpoint might interrupt the structure of an important gene, leading to male infertility. Here, we report the breakpoints on chromosome 1 translocation and the clinical features presented in carriers, to enable informed genetic counseling of these patients.

Correlation between Y chromosome microdeletion and male infertility

X. G. Liu, Hu, H. Y., Guo, Y. H., Sun, Y. P., Liu, X. G., Hu, H. Y., Guo, Y. H., and Sun, Y. P., Correlation between Y chromosome microdeletion and male infertility, vol. 15, p. -, 2016.

Dyszoospermia due to genetic factors is the leading cause of male infertility. To explore the correlation between azoospermia factor (AZF) microdeletion of the Y chromosome and male infertility, we evaluated AZF microdeletion on the long arm of the Y chromosome in 166 infertile males and 50 fertile males using multiplex polymerase chain reactions amplification and gel electrophoresis.

Association between C677T and A1298C polymorphisms of the MTHFR gene and risk of male infertility: a meta-analysis

Z., and Liu, H., Association between C677T and A1298C polymorphisms of the MTHFR gene and risk of male infertility: a meta-analysis, vol. 15, p. -, 2016.

Published studies on the association between the C677T and A1298C polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene and male infertility risk are controversial. To obtain a more precise evaluation, we performed a meta-analysis based on published case-control studies. We conducted an electronic search of PubMed, EMBASE, the Cochrane Library, the Web of Science, and the China Knowledge Resource Integrated Database for papers on MTHFR gene C677T and A1298C polymorphisms and male infertility risk.
