NCT06956287

Brief Summary

This study evaluates the effectiveness of a novel sperm-wash device designed to improve outcomes in intrauterine insemination (IUI) for couples with infertility. Traditional sperm preparation methods, such as density gradient centrifugation (DGC), are associated with elevated reactive oxygen species (ROS) levels and increased sperm DNA fragmentation, potentially compromising pregnancy rates. The new device aims to reduce these adverse effects by minimizing oxidative stress and preserving sperm DNA integrity. In this prospective, randomized controlled trial, 120 couples will be allocated to either the intervention group using the new device or the control group using DGC. The primary outcome is the clinical pregnancy rate, while secondary outcomes include sperm DNA fragmentation. The study hypothesizes that the novel device will result in higher pregnancy rates and reduced DNA fragmentation compared to DGC. These findings may support its use as a more physiological approach to sperm preparation in fertility treatment.

Outcome Measures

Primary Outcomes (1)

  • Clinical Pregnancy Rate

    Defined as the presence of an intrauterine gestational sac with fetal heartbeat confirmed by transvaginal ultrasound after intrauterine insemination (IUI). The outcome aims to evaluate the effectiveness of the novel sperm-wash device (LensHooke CA0) compared to conventional density gradient centrifugation (DGC) in improving clinical pregnancy outcomes following IUI.

    Within 6 weeks after IUI

Secondary Outcomes (1)

  • Sperm DNA Fragmentation Index (DFI)

    On the day of intrauterine insemination (IUI)

Study Arms (2)

Novel Sperm-Wash Device (CA0) Group

EXPERIMENTAL

Participants in this arm will undergo sperm preparation using the LensHooke CA0 device. The device applies a filtration and swim-up mechanism to select sperm with improved motility, morphology, and DNA integrity, while reducing oxidative stress. The processed sperm will be used for intrauterine insemination (IUI). Outcomes including clinical pregnancy rate, reactive oxygen species (ROS) levels, and sperm DNA fragmentation index (DFI) will be assessed.

Device: LensHooke CA0

Conventional DGC Group

ACTIVE COMPARATOR

Participants in this arm will undergo sperm preparation using the standard density gradient centrifugation (DGC) method. This widely used technique separates motile sperm based on density. The processed sperm will then be used for intrauterine insemination (IUI). The same outcome measures as in the experimental group will be evaluated.

Procedure: Density Gradient Centrifugation (DGC)

Interventions

The intervention involves the use of the LensHooke CA0 sperm-wash device, which incorporates filtration and swim-up techniques to isolate motile and morphologically normal sperm with intact DNA integrity. It is used for sperm preparation in intrauterine insemination (IUI) cycles. The device is designed to reduce oxidative stress and facilitate physiological sperm selection, providing a potential improvement over conventional density gradient centrifugation (DGC).

Also known as: CA0
Novel Sperm-Wash Device (CA0) Group

The control procedure involves the standard density gradient centrifugation (DGC) method, a widely accepted technique for sperm preparation in IUI. Semen samples are processed using commercially available gradient media to isolate progressively motile sperm. This method serves as the comparator to assess the clinical performance of the LensHooke CA0 device.
