Evaluation of Sperm Selection Technique Using Hyaluronic Acid Binding in

Status Completed

Clinical Trial Summary

In vitro sperm selection for ICSI is important as it has a direct influence on the paternal contribution of preimplantation embryogenesis. Various laboratory tests were developed to assess the functions of the spermatozoa. Among them, only the tests for sperm DNA fragmentation, hyperactivation of the spermatozoa and the hyaluronan-binding ability are simple and fast.

Clinical Trial Description

In vitro sperm selection for ICSI is important as it has a direct influence on the paternal contribution of preimplantation embryogenesis. Men with oligozoospermia who require ICSI often demonstrate compromised DNA integrity and increased chromosomal aberrations of the sperms in their semen. Studies have shown that embryos resulting from ICSI in those men have higher risk of sex chromosome disomies, chromosomal aneuploidies, de novo numerical chromosomal aberrations and cytogenetically detectable structural chromosomal aberrations. Although the main candidates for ICSI are oligozoospermic men, there is an increase in the use of ICSI, therefore, more couples are potentially exposed to those potential risks.

Various laboratory tests were developed to assess the functions of the spermatozoa. Among them, only the tests for sperm DNA fragmentation (Halosperm), hyperactivation of the spermatozoa and the hyaluronan-binding ability (HBA) are simple and fast enough to allow the same semen sample tested to be used for oocytes' insemination. Spermatozoa that are fail to bind to hyaluronan have many aspects of immaturity. They retain histones in the sperm nucleus, cytoplasm on the sperm neck, and have higher aberrant sperm head morphology, in addition to, lower genomic integrity. It has also been shown that sperm DNA fragmentation is associated with male factor of infertility, correlating with the morphology and motility of spermatozoa.

The aim of the present study is to carry out a comparative analysis between two groups: Hyaluronan binding system for sperm selection for ICSI procedures and another group of conventional morphology sperm selection (ICSI-PVP), both in cycles with only male infertility factor. The evaluated parameters were semen quality, fertilization and cleavage rates, chemical and clinical pregnancy, and miscarriage rates. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
