dynamic frothability index (dfi) is a characteristic of any frother which presents useful information about frothing properties. the objective of this study is to introduce a prediction model for estimation of dfi value of dual-frother blends. model uses the dfis of frothers and mole ratio of weaker frother to calculate the blend’s dfi. the model reliability was confirmed by comparing the exper...

OBJECTIVE To investigate the effectiveness of intracytoplasmic sperm injection (ICSI) using testicular sperm as a strategy to overcome infertility in men with high sperm DNA fragmentation (SDF). DESIGN Prospective, observational, cohort study. SETTING Private IVF centers. PATIENT(S) A total of 147 couples undergoing IVF-ICSI and day 3 fresh ETs whose male partner has oligozoospermia and h...

Abstract Study question In Individuals with raised Sperm DNA Fragmentation Index (DFI), will sperm selection by magnetic activated cell sorting (MACS) or Microfluidic Sorting (MF) optimize the reproductive outcomes? Summary answer MACS MF offer comparable outcomes. There seems no superiority between them. spermDFI, MACS/MF can be considered to results. What is known already It evident that DFI ...

It is generally thought that a single ejaculate is a bad predictor of semen quality of a subject, because of significant intra-individual variation. Therefore, we investigated the degree to which the results of a first semen analysis differ from that of a second analysis among men from a general population in Norway. In addition, we analysed how the two different semen results mirrored the over...

background: although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions. objective: this study was designed to investigate the effects of ginger (zingiber officinale) on sperm dna fragmentation (sdf) in infertile men. materials and methods: this randomized double-blind, placebo-controlle...

conclusions in our study, no prominent effect was seen; therefore, in order to have a better perspective of crocin activity against cancerous cell lines, further studies are highly recommended. results the highest concentration of crocin significantly decreased ros production after 48 hours of treatment. however, crocin had no effect on the expression level of hsp (heat shock protein). addition...

BACKGROUND The aim of the study was to assess the effect of four repeated ejaculations on the same day at two-hour intervals on conventional and functional semen parameters. METHODS Three healthy men (32±3.6 years) donated the first semen samples after 3-4 days of sexual abstinence followed by three subsequent samples on the same day at two-hour interval each. Semen samples were processed and...
