Lipidic Differences of Sperm Between Normal and Low Fertilization Patients
Lipidic Profiles Differences of Sperm Between Normal and Low Fertilization Male Patients in Vitro Fertilization
Study Overview
Detailed Description
There is increasing evidence that male fertility/infertility and sperm physiology are determined by multiple factors, necessitating the use of numerous molecular biomarkers to precisely assess male reproductive potential. The study has reported that the lipids are special interest as fertility markers and therapeutic targets not only due to their functions in sperm, but also because they are sensitive to external and environmental signals.
Sperm samples from infertile patients after IVF ( normal fertilization group, n=25; low fertilization group, n=25) were collected. Following standard density gradient separation operating procedure, the sample were incubated in 37°C, 5%CO2, for 3 hours. The sample included 10x10^6 spermatozoa after sample preparation and aliquots in 100 μL PBS were analyzed for lipid composition using ultra-high performance liquid chromatography coupled to mass spectrometry. Lipid compositions and levels were compared between the two groups. The results will describe the composition and contents of lipids linked to capacitation of sperm, opening a new possibilities for the development of male fertility diagnostic tools and culture media formulations to improve sperm quality and enhance fertilization result.
