Background: Fertility traits in pigs made a restricted progress through traditional selection. Applying marker assisted selection could improve these traits. The aim of the study was to investigate the effects of candidate genes Estrogen Receptor (ESR), Follicle Stimulating Hormone Beta (FSHB) and Prolactin Receptor (PRLR) on sperm quality traits of Landrace and Yorkshire boars under tropical conditions in Northern Vietnam.Methods: A total of 6306 ejaculates from 140 boars (92 Landrace and 48 Yorkshire) were collected to estimate sperm ejaculate volume (VOL), spermatozoon motility (MO), sperm concentration (CO) and total number of spermatozoon in ejaculate (NT). Ear tissue samples were collected for genotype identification of SNP present in ESR, FSHB and PRLR genes using PCR-RFLP technique. A mixed model was used to test the effect of different genetic and non-genetic factors on the sperm quality traits.Result: The genotype frequencies of ESR, FSHB and PRLR were in Hardy-Weinberg equilibrium for each breed. Age of boars and month of the year had significant effect on all the sperm quality traits (P less than 0.01) while effect of breed was found to be non-significant on all the sperm quality trait. FSHB gene significantly (P less than 0.05) affected VOL, MO and CO. Boars with BB genotype showed positive effect on VOL but negative effect on MO and CO in comparison with AA genotype boars. ESR gene showed only effect on VOL while PRLR affected only MO. Boars with AA and AB genotypes of ESR gene had a significantly higher VOL than those with BB genotype (P less than 0.05). For PRLR gen, AB genotype was associated with higher MO than AA genotype (P less than 0.05). These results suggest a possibility of using the existing polymorphisms in ESR, FSHB and PRLR genes to improve some sperm traits of Landrace and Yorkshire boars.

Mobile Phone Radiation

As mobile phone usage is growing rapidly, there is a need for a comprehensive analysis of the literature to inform scientific debates about the adverse effects of mobile phone radiation on sperm quality traits. Therefore, we conducted a meta-analysis of the eligible published research studies on human males of reproductive age. Eleven studies were eligible for this analysis. Based on the meta-analysis, mobile phone use was significantly associated with deterioration in semen quality (Hedges’s g = -0.547; 95% CI: -0.713, -0.382; p < 0.001). The traits particularly affected adversely were sperm concentration, sperm morphology, sperm motility, proportion of non-progressive motile sperm (%), proportion of slow progressive motile sperm (%), and sperm viability. Direct exposure of spermatozoa to mobile phone radiation with in vitro study designs also significantly deteriorated the sperm quality (Hedges’s g = -2.233; 95% CI: -2.758, -1.708; p < 0.001), by reducing straight line velocity, fast progressive motility, Hypo-osmotic swelling (HOS) test score, major axis (µm), minor axis (µm), total sperm motility, perimeter (µm), area (µm2), average path velocity, curvilinear velocity, motile spermatozoa, and  acrosome reacted spermatozoa (%). The strength of evidence for the different outcomes varied from very low to very high. The analysis shows that mobile phone use is possibly associated with a number of deleterious effects on the spermatozoa.

Abstract In the present study, the fertility rate and egg-hatching results from either natural mating or artificial insemination using 1- and 2-year-old domestic Turkish geese were compared. Sperm quality traits of 1- and 2-year-old ganders used for mating were determined. The study comprised 72 two-year-old females, 12 one-year-old, and 12 two-year-old ganders at the beginning of the laying period. Thirty-six female geese were mated naturally (18 with 1-year-old ganders, 18 with 2-year-old ganders); the remaining 36 were artificially inseminated (18 with 1-year-old ganders, 18 with 2-year-old ganders). Twenty-four ganders were separated into groups (12 for natural mating; 12 for artificial insemination). The male-to-female ratio in both mating protocols was 1:3. The geese were housed during the laying period in a natural and artificially ventilated house under natural lighting (increased day length). Quality traits, such as semen volume, sperm concentration, sperm quality factor (SQF), sperm motility, and some sperm morphological properties were determined. Fertility was higher in the groups containing 2-year-old ganders than in those using 1-year-old ganders (P < 0.05). The effect of insemination on semen volume, sperm concentration, SQF, sperm motility, total live sperm, normal sperm, macrocephalus sperm, and dead sperm was determined to be significant (P < 0.05). As a result, there is a need to improve the egg production and broody behavior traits of domestic Turkish geese. In addition, the use of 2-year-old geese in artificial insemination is appropriate and will contribute positively to the breeding and selection process.
