Ejaculatory Abstinence

Various studies have sought to determine the typical v. optimal abstinence period after which semen samples should be collected, with many contradictory results reported. Several factors influence the semen microenvironment, and thus sperm parameters. In this study we focused on the secretions of the prostate, seminal vesicles and the epididymis. Semen samples were obtained from healthy normozoospermic males (n=16) after 4-day and 4-h periods of ejaculatory abstinence, and standard semen analysis was performed using computer-aided sperm analysis, whereas seminal plasma citric acid, neutral α-glucosidase and fructose concentrations were measured using assay kits. There were significant decreases in total sperm count (P<0.001), sperm concentration (P<0.05) and semen volume (P<0.05) after 4h compared with 4 days ejaculatory abstinence. Furthermore, increases were observed in total sperm motility (P<0.05) and sperm progressive motility (P<0.01) after a 4-h abstinence period, accompanied by significant reductions in citric acid (P<0.05), α-glucosidase (P<0.01) and fructose (P<0.01) concentrations. In addition, due to the decreased number of spermatozoa, these concentrations translated to a significant decrease in fructose (P<0.05) per spermatozoon, indicating an intrinsic mechanism capitalising on alternative sources of energy for increased metabolic function and subsequent sperm motility.

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.

Background: Seminal hyperviscosity has been shown to be associated with male infertility. The aim of this study was to assess the prevalence of hyperviscosity in semen of Malawian males seeking infertility treatment. Methods: A total of 120 men visiting our laboratory for fertility assessment donated semen samples. The semen samples were assessed for hyperviscosity, volume, concentration, total motility, progressive motility, viability, and morphology. Results: Out of the 120 samples analyzed, 34 samples were hyperviscous representing 28.3%. No significant statistical differ- ence in semen volume between samples with normal viscosity compared to those with hyperviscosity (p>0.05). Sperm concen- tration, progressive motility, total motility, viability, and normal morphology were significantly higher in the normal viscosity group when compared to the abnormal viscocity group (p<0.05). Conclusion: Hyperviscosity affects a significant number of men in Malawi and may be the cause of decreased fertility as it was associated with poor sperm concentration, total motility, progressive motility, viability, and morphology.

Abstract Background Semen analysis is the first step to identify male factor infertility. World Health Organization estimates that male factor accounts for 50% of couple sub-fertility. The objective of this study was to determine the prevalence and patterns of male factor infertility based on semen analysis in patients visiting Massawa Hospital with infertility complaints. Methods It was a retrospective, descriptive cross sectional hospital based type of study with a census sampling method. Patient’s medical records and hospital laboratory register were used to retrieve semen analysis results of patients from June 2018 to June 2020. Ethical approval was obtained from the Ministry of Health Research and Ethical Review Committee. Confidentiality of patients records kept was secured and consent was obtained from study participants to use their data. Results were presented in frequency, tables and p value < 0.05 was considered significant. Results A total of 112 patients data was analyzed in the study with 49.1% were aged between 20 to 30 years. The prevalence of male factor infertility in these patients was found to be 42% and 79.5% of them had primary type of infertility. Of the study participants; 63 (56.3%), 72 (64.3%) and 70 (62.5%) had sperm count < 15 million sperms/ml, sperm motility < 40 % and morphology of < 60% respectively. One tenth, 15 (13.4%) of the patients had a semen volume of < 1.5ml/ejaculate, out of which 13(86.7%) had primary type of infertility. Moreover; 72 (64.3%) patients had total sperm count/ejaculate of < 39 million and 59 (82%) of these had primary type of infertility. In addition; 50.8% and 50% of patients aged 20 to 30 years had a sperm count < 15 million/ml and sperm motility of < 40% respectively. Conclusion The prevalence of male factor infertility was slightly higher and was dominated with primary infertility. Most patients had lower sperm count, sperm motility but higher semen volume, and majority of the patients with abnormal sperm results were aged between 20 to 30 years. Further prospective researches to determine the risk factors for male infertility and introducing assisted type of fertility in Eritrea are highly recommended.

Background: Several studies have reported that cigarette smoking affects sperm parameters, especially semen quality, but their results are contradictory. Objective: This retrospective study aims to evaluate the relationship of sperm parameters with smoking in men with idiopathic infertility. Materials and Methods: This retrospective study was conducted on 1744 infertile men with at least one year of idiopathic infertility. They were divided into two groups of smokers (n=379) and non-smokers (n=1365) according to their smoking habits and based on their inclusion and exclusion criteria. The semen analysis was extracted from subjects’ medical records, and the collected data were analyzed in SPSS V. 19 software. Results: Smoking significantly reduced semen volume in smokers (2.88±1.50 mL) compared to non-smokers (3.28±1.77 mL) (P=0.002). There was a significant decrease in sperm motility in smokers (36.1±21.9%) compared to non-smokers (34.4±19.6%) (P=0.009). However, the association of smoking with sperm motility between men with normal and abnormal semen volumes was not statistically significant, and there was no significant difference in sperm count and morphology between infertile smokers and non-smokers (P>0.05). Conclusion: Smoking causes a significant reduction in semen volume, but has no significant effect on sperm count, morphology, and motility in men with abnormal and normal semen volume.

Abstract The iSperm is a newly released semen analysis tool from Aidmics Biotechnology Co. LTD, which allows an iPad Mini to be transformed into a handheld microscope with objective semen analysis software for equine available through the Apple Store (version 4.5.2). The aim of this study was to compare iSperm values for sperm motility and sperm concentration to current acceptable methods for semen analysis and to determine the agreement with these methods using statistical methods. Two ejaculates from each of five Standardbred stallions were used to compare sperm motility (computer-assisted semen analysis [CASA] vs. iSperm) and concentration (NucleoCounter SP-100 [NC] vs. hemocytometer vs. iSperm). Data were analyzed by first testing for the differences between the means of each method using a linear mixed-effects model. The agreement between the two continuous measurements for each method was then investigated by computing Lin’s concordance correlation coefficient (CCC), with a value of 1 indicating perfect agreement between methods. Results are reported as the CCC with the associated 95% confidence interval in parentheses. Means for both total motility (TM) and progressive motility (PM) were equal between CASA and iSperm values (P = 0.0741 and P = 0.725, respectively). However, means for all velocity measurements were significantly different between CASA and iSperm readings (P &lt; 0.001). For concentration, means were equal between NC and iSperm values (P = 0.748) and for hemocytometer and iSperm values (P = 0.953). The CCC for TM was 0.871 (0.788, 0.923) and for PM was 0.916 (0.847, 0.955) indicating good agreement between methods. Low levels of agreement were observed for all velocity measurements. Finally, the CCC for concentration compared by iSperm and NC was 0.970 (0.949, 0.982) and for iSperm and hemocytometer it was 0.962 (0.934, 0.978), both close to the line of perfect concordance. Although more work is needed to improve the iSperm software for velocity measurements to be acceptable by research standards, in its present form the iSperm will introduce a low-cost and affordable method for on-farm semen analysis (TM, PM, concentration) for breeders and veterinarians. As a result, more farms will have access to accurate sperm analysis tools which will help to standardize semen processing procedures leading to better overall quality of semen used for artificial insemination.

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.

At present great attention is paid to studying genetic regulation of farm animal adaptations to environmental conditions. This problem is very important due to a wide expansion of highly productive cattle breeds created in Europe and North America. However, until the present no investigation of changing semen quality in bulls of imported breeds during their adaptations to environmental conditions of Western Siberia has been conducted. The aim of this study was to investigate semen quality peculiarities and the diversity of morphological sperm abnormalities in bulls of imported and local breeds kept in the environmental conditions of the southern part of Western Siberia. We determined sperm concentration, sperm count, and rate of sperm with progressive motility and percentage of morphologically normal spermatozoa. The rate of sperm abnormalities according to Blome’s classifcation was determined too. It was found that the mean values of sperm concentration, sperm motility and percentage of morphologically normal spermatozoa in the bulls investigated were similar to those in bulls kept in European countries. Inter­breed differences in these parameters were not found. However, bulls of the Red Danish, Angler, and Simmental breeds had a higher percentage of misshapen sperm head and pyriform sperm head than bulls of the Black­White breed. An inter­strain difference in sperm motility in bulls of the Black­White breed was observed. It was found that bulls of Reflection Sovereign 198998 strain had lover sperm motility than bulls of Wis Burke Ideal 1013415 strain. No inter­strain differences in sperm production, percentage of morphologically normal spermatozoa and rate of main sperm abnormalities were found. Thus, it has been found that the environmental conditions of the southern part of Western Siberia do not seriously affect the sperm production, sperm motility or percentage of morphologically normal spermatozoa in bulls. However, the increased rate of misshapen and pyriform sperm heads in the bulls of the foreign breeds points to a need to study sperm DNA fragmentation.
