Effects of combined magnetic fields on human sperm parameters
Background: In previous investigations, it has been clarified that electromagnetic fields (ELF) can cause some changes in cellular behavior. The aim of this prospective study was to investigate the effect of magnetic field (MF) on human sperm parameters of motility, morphology, and viability. Materials and Methods: Semen samples were collected from 12 fertile men, and were allowed to l...
متن کاملSperm freeze-drying; effects on sperm parameters
Today, sperm cryopreservation is a routine practice in infertility clinics. One of the alternative methods to preserve sperm is freeze-drying. This process consists of three steps. The first step is sample freezing, during which the solvent is separated from the solvent. Water forms ice crystals and the solute is placed between the ice crystals. Freezing may be done in a separate device or in a...
متن کاملThe association of follicular fluid volume with human oolemma stretchability during intracytoplasmic sperm injection
OBJECTIVE Oocyte degeneration often occurs after intracytoplasmic sperm injection (ICSI), and the risk factor is low-quality oocytes. The follicular fluid (FF) provides a crucial microenvironment for oocyte development. We investigated the relationships between the FF volume aspirated from individual follicles and oocyte retrieval, oocyte maturity, oolemma stretchability, fertilization, and dev...
متن کاملRANTES and human sperm fertilizing ability: effect on acrosome reaction and sperm/oocyte fusion.
Beta-chemokine, regulated on activation and normally T-cell expressed and presumably secreted (RANTES), is present in both the male and female genital tract fluids where its levels increase in diseases related to infertility, such as endometriosis and male genital tract infections. beta-Chemokine receptors (CCR3 and CCR5) are expressed on freshly ejaculated human sperm cells and a sperm chemoat...
