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.

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.

Abstract Cyathula prostrata (Linn.) Blume is a tropical herbal plant known for its important phytochemical contents and medicinal properties. But its impact on animal reproduction and fertility is yet to be fully established. Therefore, we tested the hypothesis that C. prostrata (Linn.) Blume will improve the semen quality characteristics of New Zealand White buck rabbit. Twenty-eight post-pubertal buck rabbits were used for the study. The animals were randomly assigned to four treatment groups (n = 7 per treatment) where they were fed either the control diet—0 g C. prostrata (Linn.) Blume or any of the three experimental diets containing the graded levels of C. prostrata (Linn.) Blume incorporated into rabbit pellets at 10, 20 or 30 g C. prostrata (Linn.) Blume per kg feed. The results showed that the semen volume and pH were not different between groups. Interestingly, sperm motility significantly decreased (P &lt; 0.05) in a dose-dependent manner. Similarly, the sperm morphology also decreased in a dose-related fashion with 20 g (77.75 ± 1.31%) and 30 g (79.00 ± 2.20%) C. prostrata (Linn.) Blume being significantly (P &lt; 0.05) lower compared with groups 0 g (88.50 ± 1.44%) and 10 g (87.50 ± 4.33%) C. prostrata (Linn.) Blume, respectively. In conclusion, the addition of C. prostrata (Linn.) Blume into the normal rabbit feeds had a positive effect on sperm count, but reduced sperm motility and morphology, and may be associated with spermatogenesis-related problems.

In 1975, semen was collected by massage from 18 randomly selected captive male American kestrels (Falco sparverius). The period of semen production extended for 103 days, beginning on March 19, while the mean duration of semen production was 73.6 days. Under natural light, semen production began at [Formula: see text] of daily light, peaked about [Formula: see text], and decline considerably around June 21 at [Formula: see text]. Weather factors, i.e., temperature, barometric pressure, did not significantly (P > 0.05) affect semen collections or quality.The following means were calculated: semen volume, 12 μl; sperm concentration, 31 000/mm3; sperm count per ejaculate, 416 000; motility score, 78%; contamination with epithelial debris and urates, 67%; and semen colour, very pale to pale amber.The following significant (P < 0.05) correlations were found: body weight with semen volume (0.48) and sperm count per ejaculate (0.54); egg fertility with sperm count per ejaculate (0.65); semen volume with sperm count per ejaculate (0.84) and sperm motility (0.54); sperm count per ejaculate with sperm concentration (0.78); and sperm motility with sperm concentration (0.59) and sperm count per ejaculate (0.75).

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&lt;0.001), sperm concentration (P&lt;0.05) and semen volume (P&lt;0.05) after 4h compared with 4 days ejaculatory abstinence. Furthermore, increases were observed in total sperm motility (P&lt;0.05) and sperm progressive motility (P&lt;0.01) after a 4-h abstinence period, accompanied by significant reductions in citric acid (P&lt;0.05), α-glucosidase (P&lt;0.01) and fructose (P&lt;0.01) concentrations. In addition, due to the decreased number of spermatozoa, these concentrations translated to a significant decrease in fructose (P&lt;0.05) per spermatozoon, indicating an intrinsic mechanism capitalising on alternative sources of energy for increased metabolic function and subsequent sperm motility.

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.

Background: About 15% married couples face problem of infertility of which male factor is implicated in 20% of them. In about 30% infertile men no causative factor is found and the condition is termed “Idiopathic”. They are often treated by empirical medications or Assisted Reproductive Technologies (ART) although success in few; our present study is carried on effects of clomephene citrate on seminal parameters in idiopathic oligospermia.Methods: This single blinded prospective randomized controlled trial was conducted at the infertility clinic with 200 idiopathic oligospermic men (sperm count <15 millions/ ml of ejaculate) after fulfilling inclusion and exclusion criteria and were alternately allocated into two equal groups - “Group C” receiving clomephene citrate tablets and “ Group P” receiving placebo after concealment. Semen analysis data were collected at baseline and every month and three months of completion of treatment and were summarized by routine descriptive statistical analysis.Results: The demographic characteristics like mean age is comparative in both groups but duration of infertility of >2 years is more in group C than group p (4.3±3.06 versus 4.1±2.57). The semen volume, spermatozoa count, sperm motility and not normal form are all increased after three months of treatment in group C as are biochemical parameters like total testosterone and serum FSH, LH and as also pregnancy rate (22% versus 4%).Conclusions: This study showed clomiphene citrate treatment protocol is inexpensive, relatively safe and easy to administer and improves semen volume, sperm count and sperm motility but not sperm morphology by increasing serum testosterone, FSH and LH in male and resulting in improved pregnancy rate in female partners.

Abstract Objectives This study aimed to access the protective effects of d-ribose-l-cysteine (DRLC) on cyclophosphamide (CPA) induced gonadal toxicity in male rats. Methods Forty-eight male Sprague-Dawley rats were divided into six groups of eight rats each. Group I the control, received distilled water (10 ml/kg), Group II received a single dose of CPA 100 mg/kg body weight intraperitoneally (i.p), Groups III and IV received a single dose of CPA at 100 mg/kg (i.p) and then were treated with DRLC at 200 mg/kg bodyweight (b.w) and 400 mg/kg b.w for 10 days, respectively. Rats in Groups V and VI received DRLC at 200 and 400 mg/kg b.w for 10 days, respectively. DRLC was administered orally. Results Results showed that CPA increased percentage of abnormal sperm cells and reduced body weight, sperm count, sperm motility, follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone levels (p<0.05). CPA also induced oxidative stress as indicated by the increased malondialdehyde (MDA) content and reduced activities of the oxidative enzymes measured (p<0.05). Liver enzymes were elevated while the blood cells production was decreased in the rats administered CPA. DRLC supplementation enhanced the antioxidant defence system as indicated in the reduced MDA levels and increased activities of the antioxidant enzymes when compared with CPA (p<0.05). Bodyweight, sperm count, sperm motility, FSH, and testosterone levels were increased in the CPA + DRLC II group compared with CPA (p<0.05). Conclusions The results of this present study showed that DRLC has a potential protective effect on CPA-induced gonadotoxicity.

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.

Infertility is a worldwide problem and in almost 50% of cases infertility results from abnormality of the male partners. Apart from endocrine disorders, definitive cause and mechanism of male infertility is not clear in many cases. Recent evidence indicates that imbalance between pro-oxidant stress and antioxidant defense plays an important role in the pathogenesis of male infertility. Among the endogenous antioxidant systems, reduced glutathione (GSH) plays a significant role in the antioxidant defense of the spermatogenic epithelium, the epididymis and perhaps in the ejaculated spermatozoa. The current study was therefore designed to evaluate any association that may exist between GSH levels and male infertility. Infertile male patients (having female partners with normal fertility parameters; n=31) and age- matched healthy male fertile control subjects (n=30) were included in this study. In addition to medical history, semen analyses including semen volume, sperm count, motility and morphology were done for each subject. As a measure of antioxidant capacity erythrocyte and seminal plasma GSH concentrations were measured by Ellman's method in fertile and infertile male subjects. The infertile subjects were similar to fertile subjects in terms of age. However, semen volume and sperm count was found significantly lower (p<0.001) in infertile males compared with healthy fertile male subjects. Percentage of subjects with abnormal sperm morphology and motility were found higher in infertile group compared with fertile group. The median (range) erythrocyte GSH level did not differ between the two groups (12.62 (0.67-29.82) versus 13.93 (2.10-21.08) mg/gm Hb). However, the seminal plasma GSH level was found markedly suppressed in infertile group (1.64 (0.23-7.50)) compared with fertile group (4.26 (2.32-7.50)) mg/dl (p<0.001). In the present study seminal plasma GSH level was found markedly suppressed along with abnormal values for semen volume, sperm concentration and sperm morphology and motility in infertile subjects compared with fertile subjects. This finding indicates that low level of seminal plasma GSH level may be associated with male infertility. DOI: http://dx.doi.org/10.3329/bjmb.v4i2.13772 Bangladesh J Med Biochem 2011; 4(2): 20-25
