Testosterone to Luteinizing Hormone Ratio as a Potential Predictor of Sperm Retrieval in Non-Obstructive Azoospermia Patients.
This study assessed the outcomes of microsurgical testicular sperm extraction (mTESE) and potential preoperative predictors of sperm retrieval (SR) in patients with non-obstructive azoospermia (NOA). ⋯ In addition to traditional predictors, such as testicular volume and preoperative FSH levels, the T/LH ratio is a potential independent predictor of successful SR in infertile patients with NOA.

Relationship between Time Elapsed Since Pain Onset and Efficacy of Pain Relief in Patients Undergoing Lumbar Percutaneous Epidural Adhesiolysis.
The aim of this study was to investigate the relationship between pain duration and pain relief after epidural adhesiolysis. ⋯ Pain lasting ≥3 years prior to lumbar epidural adhesiolysis was associated with worse outcomes in terms of pain relief. Therefore, this intervention should be considered early before pain chronification in patients with low back pain.
