COVID-19 and fertility: a virtual reality
(2020)The COVID-19 pandemic is an extraordinary global situation, and all countries have adopted their own strategies to diminish and eliminate the spread of the virus. All measures are in line with the recommendations provided ... -
Cumulative pregnancy rate after ICSI with cryopreserved testicular tissue in non-obstructive azoospermia
(2005)The aim of the present study was to describe a simplified and inexpensive method of testicular tissue freezing to assess the cumulative clinical pregnancy rate (CPR) by this technique, and to provide useful information for ... -
The effect of glyphosate on human sperm motility and sperm DNA fragmentation
(2018)Glyphosate is the active ingredient of Roundup®, which is one of the most popular herbicides worldwide. Although many studies have focused on the reproductive toxicity of glyphosate or glyphosate-based herbicides, the ... -
Effect of plasmin on movement characteristics of ejaculated bull spermatozoa
(2004)Proteolytic enzymes appear to have an essential role in multiple phases of mammalian fertilization. Several observations suggest that the plasminogen activator/plasmin system might also play a role in mammalian fertilization. ... -
Factors affecting outcome after ICSI with spermatozoa retrieved from cryopreserved testicular tissue in non-obstructive azoospermia
(2005)There is a lack of data regarding variables affecting the treatment outcome for non-obsructive azoospermia when spermatozoa from cryopreserved testicular specimens are utilized for ICSI. The objective of the present ... -
The impact of sars-cov-2 on sperm cryostorage, theoretical or real risk?
(2021)Cryopreservation of human gametes and embryos as well as human reproductive tissues has been characterized as an essential process and aspect of assisted reproductive technology (ART). Notably, sperm cryopreservation is a ... -
Laparoscopic intrauterine insemination in superovulated Chios breed ewes [Λαπαροσκοπική ενδομητριαία σπερματέγχυση σε προβατίνες φυλής Χίου μετά από πρόκληση πολλαπλής ωοθυλακιορρηξίας]
(2018)In this study the standardization of a simplified method for laparoscopic insemination of ewes is described and the firstresults of its application in 26 donors ewes of Chios breed.Superovulation was induced by i.m. ... -
Pregnancy prediction by free sperm DNA and sperm DNA fragmentation in semen specimens of IVF/ICSI-ET patients
(2016)Abstract: The purpose of this study was to evaluate the predictive value of free sperm plasma DNA (f-spDNA) and sperm DNA fragmentation (SDF), in semen specimens from men undergoing in vitro fertilization/intracytoplasmic ... -
The Protective Role of Melatonin in Sperm Cryopreservation of Farm Animals and Human: Lessons for Male Fish Cryopreservation
(2022)Cryopreservation is a technique that offers various advantages, especially in fish, among others, that makes the reproduction of species easier through a constant supply of sperm, synchronization of the gamete availability ... -
Replicating a GWAS: two novel candidate markers for oligospermia in Greek population
(2021)Genome-wide association studies have paved the way for the discovery of new markers regarding many diseases, including male infertility. A previous study on Caucasians highlighted 172 polymorphisms for their putative ... -
SARS-CoV-2 vs. human gametes, embryos and cryopreservation
(2021)The COVID-19 pandemic, caused by the SARS-CoV-2 virus, is an unprecedented global situation, and all countries have adopted their own measurements to mitigate the spread of the virus in the first as well as in the subsequent ... -
Sperm contributions to oocyte activation: more that meets the eye
(2016)It is well known that for successful fertilization, oocyte activation is required, which involves a signal transduction cascade leading to the conversion of the oocyte to a diploid embryo. During oocyte activation, ...
