N normal phenotype
reproductive system
• reduction in testes size in adults which is attributed to missing cell populations beyond the late pachytene spermatocyte stage
• spermatogenic arrest in late pachytene spermatocytes
• a higher amount of R-loop structures are detected in the testis, especially in the pachytene spermatocyte nucleoplasm

endocrine/exocrine glands
• reduction in testes size in adults which is attributed to missing cell populations beyond the late pachytene spermatocyte stage
