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.

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.

An experiment was undertaken to determine the conception rate of native sheep by using Artificial Insemination with liquid ram semen. The semen was collected from ram using artificial vagina and the was stored in a refrigerator (4°C) for three days. The volume of semen was extended with egg yolk citrate diluter. A total of 63 ewes were inseminated with stored liquid semen collected from 15 rams by AV method. The total number of spermatozoa, live-dead, normal-abnormal, sperm motility and the pH was observed regularly. The average semen volume per ejaculate was 0.76-1.00ml and the sperm concentration was 2.37x109 - 4.30x109 per ejaculate. The number of normal spermatozoa and the pH was almost similar irrespective of days of storage. Number of live spermatozoa and the sperm motility were reduced with the increasing age of semen. The average conception rate (%) was obtained as 63.61, 61.90, 52.38 and 47.61 with sperm in zero, 1st, 2nd and 3rd day storage respectively.

The purpose of this study was to examine sperm quality after cryopreservation of ejaculates collected as a bulk sample, which is routinely part of semen collection, and to compare this quality with the sperm-rich fraction in boars. Ejaculates were collected as sperm-rich fractions (SRF) and bulk samples (BE) using a gloved-hand technique. Fresh semen quality in terms of semen volume, sperm concentration, total sperm motility and pH were conventionally evaluated. Then, semen was cryopreserved using the liquid nitrogen vapour method. The post-thaw sperm quality was evaluated by assessing sperm motility, live sperm with normal apical ridge and high mitochondrial energy status, lipid peroxidation was evaluated using CASA and fluorescent multiple staining and MDA levels were determined using a spectrophotometer, respectively. In terms of fresh semen quality, sperm motility in fresh semen did not differ significantly between the two groups. The treatment with the greater mean volume (BE; P &lt; 0.05) had a lower mean sperm concentration (P &lt; 0.05); meanwhile, the mean ejaculate pH collected as BE was more basic compared with SRF (P &lt; 0.05). However, there were no significant post-thaw quality changes between sperm-rich fractions and bulk samples of semen. In conclusion, ejaculates can be collected as bulk samples without the need to classify fractions for boar semen cryopreservation.

Background: Infertility is a major cause of marital disharmony in Nigeria because of the high premium placed on childbearing. Unfortunately, the blame is on the woman most times in Nigeria. Seminiferous tubules comprise 80-90% of testicular mass. Thus, the testicular volume is an index of spermatogenesis. Therefore, accurate testicular volume will help in assessing testicular function if there is no obstruction. This study was conducted to evaluate the correlation between testicular volume, measured by ultrasound and conventional sperm parameters (semen volume, sperm concentration, sperm motility and sperm morphology) in men with infertility presenting to Urology Division, University of Abuja Teaching Hospital, Gwagwalada Abuja. Methodology: This was a descriptive cross sectional study, male subjects with infertility presenting to University of Abuja Teaching Hospital were recruited into the study. The testicular volume of all the subjects was measured by ultrasonography. The semen samples were collected by the process of masturbation on day five of sexual abstinence and analyzed according to WHO criteria 2010. Collated data were analyzed using SPSS version 20.0. P-value<0.05 was taken as statistically significant. Results: The average total testicular volume (TTV) of men with infertility was 19.83 ml while mean testicular volume (MTV) was 10.24 ml. There was a statistically significant difference between MTV and semen volume (r=0.391, p=0.000), and sperm concentration (r=0.639, p=0.000). There was a weak and insignificant correlation between MTV and sperm motility and MTV and morphology (r=0.216, p=0.055 and r=0.076, p=0.502) respectively. Linear regression analysis showed significant impact of MTV (P<0.001) on sperm concentration with a critical MTV of ≤10ml.0 indicating poor testicular function (severe oligospermia) Conclusion: The mean ultrasonic testicular volume in men with infertility in this study was 10.24ml and there was a significant positive correlation of MTV with semen volume and sperm concentration. Although, there was correlation of MTV with sperm motility and morphology, this was not significant. The critical mean ultrasonic testicular volume indicating poor testicular function (severe oligospermia) was found to be 10ml. This study has shown that the mean ultrasonic testicular volume can be a pointer to semen volume and sperm concentration in evaluating men with infertility.

Abstract This study compared the semen quality traits between Etawah grade (EGB) and Senduro bucks (SB) raised in Singosari National Artificial Insemination Center, Indonesia. A total of 96 ejaculated semen were collected from three EGB and three SB with an average age of three years. The ejaculates were evaluated for semen volume (SV), spermatozoa concentration (SC), total spermatozoa (TS), spermatozoa motility (SM), post-thawing spermatozoa motility (PTSM), the recovery rate of spermatozoa motility (RRSM), and frozen semen production (FSP). Data of SV, SM, PTSM, and RRSM were compared using the Mann-Whitney U test. While the data of SC, TS, and FSP were analyzed using an independent t-test. The results showed that SV, SM, PTSM, and RRSM were not significantly differed (P>0.05) between breeds. Whereas, SC, TS, and FSP of EGB were significantly higher (P<0.05) than SB. Therefore, it can be concluded that Etawah grade bucks can produce higher total spermatozoa and as a result higher frozen semen production for artificial insemination as compared to Senduro bucks.

The aim of this experimental study was to evaluate whether infertile patients may benefit from the evaluation of bio-functional sperm parameters in addition to the conventional semen analysis. To accomplish this, we evaluated the correlation between conventional and bio-functional sperm parameters based on their percentile distribution in search of a potential threshold of these latter that associates with conventional sperm parameter abnormalities. The study was conducted on 577 unselected patients with infertility lasting at least 12 months. We identified cut-off values according to the median of the population for mitochondrial membrane potential (MMP), number of alive spermatozoa, and chromatin abnormality. High MMP (HMMP) (≥46.25%) was associated with sperm concentration, sperm count, progressive motility, and normal form. Low MMP (LMMP) (≥36.5%) was found to be associated with semen volume, sperm concentration, total sperm count, progressive motility, total motility, and normal form. The number of alive spermatozoa (≥71.7%) was associated with sperm concentration and progressive motility whereas abnormal chromatin compactness (≥21.10%) was associated with sperm concentration, total sperm count, and progressive motility. The data would suggest that, for every increase in the percentile category of sperm concentration, the risk of finding an HMMP≤46.25 is reduced by 0.4 and by 0.66 for a total sperm count. This risk is also reduced by 0.60 for every increase in the percentile category of sperm progressive motility and by 0.71 for total sperm motility. Each increment of percentile category of the following sperm parameter was followed by a decrease in the risk of finding an LMMP≤36.5: sperm concentration 1.66, total sperm count 1.28, sperm progressive motility 1.27, total sperm motility 1.76, and normal form 1.73. Lastly, the data showed that, for every increase in the percentile category of total sperm count, the risk of finding an abnormal chromatin compactness ≤21.10 is reduced by 1.25 (1.04–1.51, p < 0.05) and an increase of total sperm motility is associated with a reduced risk by 1.44 (1.12–1.85, p < 0.05). Results suggest a correlation between bio-functional and conventional sperm parameters that impact the sperm fertilizing potential. Therefore, the evaluation of bio-functional sperm parameters by flow cytometry may be useful to explain some cases of idiopathic male infertility.

Sperm motility is known to affect fertilization; however, little is known about the relationship between frozen–thawed sperm motility and in vivo fertilization following superovulatory treatment. The objective of this study was to evaluate a sperm function test as potential predictors of embryo production following superovulatory treatment in cattle. Two to five batches of semen (Japanese black bull, n = 4, A to D) were diluted with egg york-citrate-glycerol in 0.5 mL plastic straws, and they were stored in liquid nitrogen until analyzed. Frozen–thawed spermatozoa were evaluated for motility {motile sperm concentration (MSC, million mL–1), progressive MSC (PMSC, million mL–1) and velocity (μm s–1)} using a sperm quality analyzer for bulls (SQA-Vb, Medical Electronic Systems, Caesarea, Israel). Each sample of 20 μL aspirated into the disposable capillary, was inserted into SQA-Vb. Measurements were displayed within 75 s. Intra-assay CVs of MSC, PMSC, and velocity were 14.2, 7.3 and 7.5%, respectively. Inter-assey CVs of them were 13.5, 3.9 and 4.3% respectively. Superstimulated donors (Japanese black cows, n = 161) were artificially inseminated with one dose of frozen–thawed semen (bull A = 74, B = 46, C = 21 and D = 20). The proportion of transferable embryo (IETS grade 1 to 3) was examined on day 7 (day 0 = estrus). Data were analyzed using ANOVA followed by Scheffe multiple comparison test, and Fisher’s z-transformation. MSC, PMSC and velocity values differed significantly among each bull. The values of bull A were much lower than those of the other bulls. The proportion of transferable embryos produced by bull A was significantly lower than that of other bulls (P < 0.05, Table 1). Correlations showed significant association between MSC and proportion of transferable embryos (r = 0.99, P < 0.01). We conclude that bovine sperm motility using a SQA-Vb is a useful predictor of embryo production following superovulatory treatment.

Inbreeding depression, a genetic condition produced by the mating of close-related individuals, has been associated with a reduction of fertility in several species. However, a loss in sperm quality was also associated with age. In horses, the few existing reports have described a tendency of both parameters to produce a negative effect on sperm quality. However, those reports were performed using a subjective evaluation of sperm motility. In the present study, a total of 692 ejaculates from 86 Pure Spanish stallions (PRE), aged between 3 and 22 years, were evaluated using a computer-assisted methodology to determine the effect of inbreeding in four semen parameters: free-gel volume (V), sperm concentration (C, by haemocytometer), and total (TM) and progressive (PM) sperm motility (by Spermvision sperm class analyser; Minitube). The inbreeding coefficient (F) was estimated using 300 000 PRE pedigree records approximately (minimum pedigree depth, eight equivalent complete generations; range, between 1 and 30.1%). Stallion, age, ejaculate, and season of semen collection were the variables included in the statistical model (general linear model), with ejaculate and season being the variables with a major effect (by variance components analysis). Our results showed that sperm concentration (r=−0.18; P&lt;0.0001) and volume (to a lesser extent) were reduced with advancing age, both showing a major decline after 15 years of age. To the contrary, sperm motility was not affected by age of the stallion. We also found a negative correlation between the inbreeding coefficient and ejaculate volume (r=−0.14; P&lt;0.001), with a marked decrease seen when F was between 7 and 20%. Also, a negative correlation was observed in PM (r=−0.08; P&lt;0.05), although to a lower extent. Conversely, C and TM were not affected by inbreeding depression (P&gt;0.05). In conclusion, our results demonstrated that high levels of inbreeding can compromise severely the sperm quality of the PRE stallion, which, subsequently, may have a negative influence on fertility. Ongoing studies using genomic data will help to detect genetic variants associated with stallion semen quality and how it is influenced by inbreeding in specific genomic regions.
