Reproduction technologies in pig farming: artificial insemination - literature review

Vet. zootec; 31 (), 2024
This summary addresses the use of reproduction technologies in swine farming, with an emphasis on artificial insemination (AI). Brazilian swine farming has been growing significantly and seeks new technologies to achieve high productive indices sustainably and competitively. Pigs present favorable charac...

Postnatal Exposure to Exogenous progesterone Exacerbates the Prenatally-Induced Abnormal Sperms Production and Function in Rats

Int. j. morphol; 41 (4), 2023
SUMMARY: This study aimed at clarifying the impact of long-term prenatal and postnatal exposure to exogenous progesterone on sperm production and function, relative sex organs weights, and the levels of the relevant hormones in rats. Sixty male Wistar rats were included and classified into three groups (...

Use of antioxidants and time of cold storage: effects over viability parameters and enzymatic levels in semen of rainbow trout (Oncorhynchus mykiss, Walbaum, 1792)

Braz. j. biol; 83 (), 2023
Abstract The cold storage of milt implies potentials alterations in its quality because the storage generates as main process, free radicals that produce spermatozoa membrane lipids damage with the consequent motility and fertilising capacity disruptions. To decrease the damage generated by free radicals...

Cyperus esculentus L. protects testis and sperm morphology of hyperglycaemic rats

Cyperus esculentus L. (tiger nut) is a tuberous plant that promotes and protects reproductive functions, which are usually hampered in diabetics. The present study investigated the effect of Cyperus esculentus tuber extract (CETE) on testicular histology and sperm viability of all...

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 ...

Examination of clinical data and semen analysis results of patients undergoing orchiectomy for testicular tumor

SUMMARY OBJECTIVE: Testicular tumor constitutes 1% of male neoplasms. Infertility can be determined in patients with testicular tumors before orchiectomy due to the deterioration of spermatogenesis. The aim of this study was to show the clinical, radiological, and pathological characteristics and spermi...

The importance of updated criteria in breeding soundness examination of commercial Nellore bulls for the herd reproductive improvement

The aim of this work was to compare results of breeding soundness examination (BSE) of Nellore bulls (n=1257) according to evaluation criteria from two different classification tables (traditional-Table1 used since 1997 and an updated-Table2-proposed in 2020). Data were separated into 3 categories: quest...

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...

The association of seminal oxidation reduction potential with sperm parameters in patients with unexplained and male factor ınfertility

Int. braz. j. urol; 47 (1), 2021
ABSTRACT Purpose: Understanding the effects of high oxidation reduction potential (ORP) levels on sperm parameters will help to identify patients with unexplained and male factor infertility who may have seminal oxidative stress and determine if ORP testing is needed. This study aimed to evaluate the as...
