This case report describes a severely oligozoospermic patient diagnosed with both mosaic Klinefelter syndrome and a complete azoospermia factor c (AZFc) Y chromosome microdeletion. The authors present the clinical findings and genetic analysis of this rare co-occurrence, highlighting the complex interplay between chromosomal abnormalities and Y-chromosome deletions in male infertility. No major limitations are explicitly stated beyond the inherent constraints of reporting a single individual case. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
