Is this trial a fit for you?

Likely a good fit

Subfertile men aged 20–50 with confirmed asthenozoospermia (total motility 20% to <42%) who meet the listed inclusion and exclusion criteria are eligible.

Probably not a fit

Men with severe oligoasthenoteratozoospermia, recent antioxidant use, certain medical/endocrine/genetic disorders, prior chemo/radiotherapy, genital infection or surgery, substance abuse, or hypersensitivity to xanthine products are excluded and unlikely to benefit from this protocol.

What this trial studies

This is a randomized, controlled trial enrolling 56 subfertile men with asthenozoospermia at Bangladesh Medical University. Participants are randomly assigned to receive pentoxifylline 400 mg twice daily plus CoQ10 100 mg twice daily, or CoQ10 100 mg twice daily alone, for three months. Baseline semen analysis requires two samples and the main outcome is change in sperm motility after three months, with monitoring for adverse events. Allocation is concealed using serially numbered opaque envelopes and safety and demographic data are collected throughout.

Why it matters

Potential benefit: If successful, the combination could improve sperm motility and may increase the chances of conception for affected men.

How similar studies have gone: Previous studies report modest improvements in sperm parameters with CoQ10 or pentoxifylline individually, but randomized data on their combined use are limited.
