BRD2 and cryptorchidism: Compared to other NOA patients, a man with a history of cryptorchidism tends to have a slightly higher chance of sperm retrieval, and even if he had a history of bilateral cryptorchidism, mTESE will lead to find sperm in up to 62% [10, 38].SRR is also correlated to a subnormal testicular volume but independant from FSH [39].
