Actual (reported)

Patients with non-obstructive azoospermia (NOA), (absence of spermatozoa in multiple semen analyses)

Patients with cryptozoospermia, (presence of a small number of spermatozoa detectable only after semen centrifugation)

Patients with oligoasthenoteratozoospermia (OAT), (sperm concentration of less than 15 million/mL, reduced motility and abnormal morphology)

You may not qualify if:

Patients who did not have any sperm noted following micro-TESE
Use of donor sperm or oocytes
Frozen sperm or oocytes
Same day oocyte retrieval and sperm extraction
Reversible cause of cryptozoospermia (i.e presence of a varicocele, febrile illness, or recent toxin exposure) Partial genital tract obstruction (i.e post-vaso-vasostomy, post-vasoepididymostomy, and low volume cryptozoospermia with ejaculatory duct obstruction)
