What this trial studies

This clinical trial investigates the efficacy of TetraSOD®, a marine phytoplankton extract, in improving semen quality in men with idiopathic infertility. The study will administer a lower dose of 125 mg/day to assess its effectiveness compared to previous trials that used a higher dose. Participants will be male patients aged 18 to 45 who have been diagnosed with specific forms of infertility after a year of unsuccessful attempts to conceive. The trial aims to explore the relationship between oxidative stress and male fertility, potentially offering new insights into treatment options.

Who should consider this trial

Good fit: Ideal candidates are men aged 18 to 45 with idiopathic infertility characterized by asthenozoospermia, oligozoospermia, or oligoasthenozoospermia.

Not a fit: Patients with azoospermia, severe oligozoospermia, or other significant health issues such as diabetes or recent surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve fertility outcomes for men suffering from idiopathic infertility.

How similar studies have performed: Previous studies using similar marine phytoplankton products have shown promising results in improving semen quality, suggesting a potential for success in this trial.
