Apoptosis is an ongoing physiological phenomenon that has been documented to play a
role in male infertility, if deregulated. Caspase activation, externalization of …

Background Semen preparation techniques for assisted reproduction, including intrauterine
insemination (IUI), were developed to separate the motile morphological normal …

Male infertility often involves idiopathic or unknown causes, leading to an increasing
demand for assisted reproduction technologies (ART). Conventional sperm sorting …

Objective To validate a set of five microRNAs (miRNAs) as specific biomarkers for the
assessment of male infertility. Design Quantitative real-time polymerase chain reaction (qRT …

OBJECTIVE: To investigate sperm viability, incidence of apoptosis, and intracellular basal
and induced reactive oxygen species (ROS) in sperm fractions. DESIGN: Prospective …

On the one hand, reactive oxygen species (ROS) are mandatory mediators for essential
cellular functions including the function of germ cells (oocytes and spermatozoa) and …

Human sperm samples are very heterogeneous and include a low amount of truly functional
gametes. Distinct strategies have been developed to characterize and isolate this specific …

An appropriate preparation technique, should be capable of isolating highquality
spermatozoa for intracytoplasmic sperm injection (ICSI). The aim was to assess sperm …

Purpose DNA damage may occur during sperm processing, thereby negatively influencing
fertilizing ability of the sperm. The present study was designed to compare the effectiveness …

Purpose To compare the efficacy of swim-up and DGC in improving sperm deformity and
DNA fragmentation and to determine which method is better in teratozoospermic patients …
