BACKGROUND In assisted reproduction procedures, we need to develop and enhance new protocols to optimize sperm selection. The aim of this study is to evaluate the ability of the Z potential technique to select sperm with intact DNA in non-normospermic patients and evaluate the impact of this selection on embryonic development. METHODS We analyzed a total of 174 human seminal samples with at l...

Background Use of cellular phones emitting radiofrequency electromagnetic field (RF-EMF) has been increased exponentially and become a part of everyday life. This study aimed to investigate the effects of in vitro RF-EMF exposure emitted from cellular phones on sperm motility index, sperm DNA fragmentation and seminal clusterin (CLU) gene expression. MaterialsAndMethods In this prospective stud...

The ZyMōt sperm separation device has proven favorable for use in elevated DNA fragmentation index (DFI) male factor patients, as an alternative to density gradient (DG) washing or surgically attained testicular sperm. In 2020, without fully understanding the infectivity and transmission potential of SARS-CoV2 semen, a more liberal application timed microfluidic swim-up was applied our IVF pati...

Background: Techniques of sperm preparation require centrifugation to separate spermatozoa from the seminal plasma. The centrifugation can induce damage to the spermatozoa and increase reactive oxygen species(ROS) productionspecially in leukospermic speciemens that are associated with impaired function and fertilizing capacity. However in ICSI, fertilization can occure with damage DNA sperm but...

Based on panel data from the National rural fixed point survey 2011 to 2018 and Peking University digital financial inclusion (DFI) index data, this article uses dynamic effect model analyze of access inclusive financing platforms agricultural total factor productivity (TFP) its contributing factors at household level. The results show that DFI have a significant hysteresis positive impact TFP ...

a new method was introduced for frothing characterization of flotation frothers. method uses water recovery to develop a new frothability index named water recovery index (wri). new index was determined for some commercial frothers and results were compared with dynamic frothability index (dfi). results showed that water recovery index values follow the order of a-65 13016 s/mol > df-250 6292.4...

OBJECTIVE To evaluate the impact of atopic dermatitis on the quality of life of pediatric patients in the age group of 5-16 years, and their parents, assisted at the Dermatology Department of Universidade do Estado do Pará in 2015. METHODS A cross-sectional study including 51 patients and their guardians, to whom two questionnaires about the quality of life were applied, the Children's Dermat...

quality of life of pediatric patients in the age group of 5–16 years, and their parents, assisted at the Dermatology Department of Universidade do Estado do Pará in 2015. Methods: A cross-sectional study including 51 patients and their guardians, to whom two questionnaires about the quality of life were applied, the Children’s Dermatology Life Quality Index (CDLQI) and the Dermatitis Family Imp...

background: sperm dna fragmentation is known as an important cause of male infertility. the influence of sperm dna damage on reproductive potential has been subject of many studies indicating various results and remaining the subject controversial. in this study, we investigated differences of the semen parameters and intracytoplasmic sperm injection (icsi) outcome according to sperm dna fragme...

Background: Infertility is estimated to affect up to 15% of couples of reproductive age, and male factors contribute to 50% of these cases. Globozoospermia syndrome is a severe form of teratozoospermia, with an incidence of less than 0.1%. It is characterized by round sperm head. The most prominent feature of globozoospermia is the malformation of the acrosome, which is totally absent in the to...
