Using Pentoxifylline to Improve Sperm Selection in Infertile Men

The Efficacy of Pentoxifylline on Sperm Selecting in Intracytoplasmic Sperm Injection (ICSI) of Absolute Asthenozoospermia

Not applicable Interventional Mỹ Đức Hospital · NCT05943353

This study is testing if a medication called Pentoxifylline can help improve sperm selection for men with very low sperm movement to increase their chances of successful fertilization during a specific fertility treatment.

What this trial studies

This study investigates the use of Pentoxifylline, a drug that enhances sperm motility, to improve the selection of viable sperm for intracytoplasmic sperm injection (ICSI) in men with absolute asthenozoospermia, a condition characterized by complete immobility of sperm. The research aims to evaluate the effectiveness of Pentoxifylline in increasing fertilization rates by allowing embryologists to identify live but immotile sperm. The study will involve patients who have undergone sperm collection through procedures like PESA or TESE, where sperm motility is severely compromised. By assessing the outcomes of ICSI with Pentoxifylline, the study seeks to optimize treatment protocols for male infertility.

Who should consider this trial

Good fit: Ideal candidates for this study are men diagnosed with absolute asthenozoospermia who have completely immotile sperm after ejaculation or surgical sperm collection.

Not a fit: Patients who have viable motile sperm or those undergoing oocyte maturation cycles in vitro may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance fertility treatment outcomes for men with severe sperm motility issues.

How similar studies have performed: While the application of Pentoxifylline in ICSI has not been previously tested in Vietnam, other studies have shown promising results in enhancing sperm motility and selection in similar contexts.
