Study Question: Which independent factors influence ICSI outcomes in patients with complete azoospermia factor c (AZFc) microdeletions?

Summary Answer: In patients with complete AZFc microdeletions, the sperm source, male LH, the type of infertility in women, and maternal age are the independent factors associated with ICSI outcomes.

What Is Known Already: AZF microdeletions are the second most prevalent factor contributing to infertility in men, with AZFc microdeletions being the most frequently affected locus, accounting for 60-70% of all cases. The primary clinical phenotypes are oligoasthenozoospermia and azoospermia in patients with complete AZFc microdeletions.

Article Synopsis
  • A study was conducted to evaluate how factors like body mass index (BMI) and age affected surgical outcomes for patients with epididymal obstruction undergoing vasoepididymostomy (VE).
  • Involving 181 patients with obstructive azoospermia, the research analyzed various factors related to surgical success rates through statistical methods.
  • Results showed that younger patients (≤28 years) and those with a lower BMI (<26.0 kg/m²) had significantly better patency rates, highlighting the importance of these factors in treatment planning.

Background: Urolithiasis is a significant healthcare issue but the pathophysiology of stone disease remains poorly understood. Drosophila Malpighian tubules were known to share similar physiological function to human renal tubules. We have used Drosophila as a genetic model to study the transcriptional response to stone formation secondary to dietary manipulation.

Kidney stone disease is a major health burden with a complex and poorly understood pathophysiology. Drosophila Malpighian tubules have been shown to resemble human renal tubules in their physiological function. Herein, we have used Drosophila as a model to study the proteomic response to crystal formation induced by dietary manipulation in Malpighian tubules.

Many centres favour endourological management over shock wave lithotripsy (SWL) in the management of moderate-sized (10-20 mm) renal stones. International guidelines support all available modalities for the treatment of these stones. The aim of this study was to evaluate the efficacy of SWL in the treatment of 10- to 20-mm renal stones.
