Male
Phenotype

In vitro clinic: Very low testis weight, no epididymal sperm recovered.

Histology evaluation: Arrest of spermatogenesis predominantly at pachytene stage of meiotic prophase or meiotic division stage (see 1), some germ cells appear apoptotic (see 2).

Female
Phenotype

In vitro clinic: No oocytes recovered.

Histology evaluation: Tiny ovaries with no growing oocytes or follicles (see 3).
