What this trial studies

This clinical trial evaluates a new protocol called ANTIUI aimed at improving ovulation and pregnancy rates in patients diagnosed with unexplained infertility. Participants will undergo treatment with gonadotropins and a standard intrauterine insemination (IUI) protocol. The study focuses on individuals who have normal hormonal and structural evaluations but have not achieved pregnancy after a reasonable duration of trying to conceive. The goal is to provide an alternative option before considering more invasive procedures like ICSI.

Who should consider this trial

Good fit: Ideal candidates are women under 35 years with unexplained infertility lasting less than 5 years and good ovarian reserve.

Not a fit: Patients over 35 years, those with a longer duration of infertility, or those with abnormal semen analysis will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the chances of conception for patients facing unexplained infertility.

How similar studies have performed: Other studies have shown promising results with similar protocols, indicating potential for success in this approach.
