Effects of Jinkui Shenqi and Wuzi Yanzong pill on sperm motility and sperm DNA fragmentation rate in asthenospermia

Biosci. j. (Online); 38 (), 2022
This study was designed to compare the effects of Jinkui Shenqi and Wuzi Yanzong pill on sperm motility and sperm DNA fragmentation rate in patients with asthenospermia. 130 cases were randomly divided into an observation and control group (n=65). The control group was treated with the Wuzi Yanzong pill ...

The combined effect of lifestyle intervention and antioxidant therapy on sperm DNA fragmentation and seminal oxidative stress in IVF patients: a pilot study

Int. braz. j. urol; 48 (1), 2022
ABSTRACT Purpose: Sperm DNA fragmentation (SDF) and seminal oxidative stress are emerging measurable factors in male factor infertility, which interventions could potentially reduce. We evaluated (i) the impact of lifestyle changes combined with oral antioxidant intake on sperm DNA fragmentation index (...

Sperm DNA damage compromises embryo development, but not oocyte fertilisation in pigs

Biol. Res; 55 (), 2022
BACKGROUND: The assessment of sperm DNA integrity has been proposed as a complementary test to conventional mammalian semen analysis. In this sense, single-strand (SSB) and double-strand (DSB) DNA breaks, the two types of sperm DNA fragmentation (SDF), have been reported to have different aetiologies and...

Oxidative origin of sperm DNA fragmentation in the adult varicocele

Int. braz. j. urol; 47 (2), 2021
ABSTRACT Purpose: Sperm DNA fragmentation is a major cellular mechanism underlying varicocele-related male infertility. However, the type of DNA fragmentation - whether oxidative or of another nature - remains unknown. Thus, the aim of this study was to evaluate single- and double-stranded sperm DNA fra...

Assessment of heavy metals and its impact on DNA fragmentation in different fish species

Braz. j. biol; 80 (4), 2020
Abstract This study was conducted to assess water pollution by examining DNA fragmentation in selected fish organs (kidney, liver, gills, and muscle tissue) from Wallago attu, Sperata sarwari, Vulgaris vulgaris, and Labeo rohita collected from a known polluted section of the Chenab River, Pakistan, and f...

Fragmentación del ADN espermático en parejas tratadas por fertilización in vitro
