Some 30% to 80% of male sub-fertility may be associated with oxidative stress that damages spermatozoa and can decrease success of in vitro fertilization (IVF) techniques. This multicenter, longitudinal, prospective study aimed to investigate whether oral antioxidant supplementation improved the reproductive competence of men who had had low fertilization rates in their previous intracytoplasmic sperm injection (ICSI) cycles without azoospermia or severe oligozoospermia or any identifiable andrological disease. Seventy-seven men from couples who had an ICSI attempt with unexplained <60% fertilization rate took an antioxidant mix of myo-inositol, alpha-lipoic acid, folic acid, coenzyme Q10, zinc, selenium, and vitamins B2, B6, and B12. Semen parameters were analyzed before (T0) and after 90 days (T90) of treatment, and outcomes of the paired T0 and T90 cycles were compared. After the treatment there was an increase in sperm concentration (p = 0.027), total motile sperm count (p = 0.003), progressive motility (p < 0.0001), and a decreasing trend of DNA-fragmented spermatozoa. Embryological outcomes (fertilization, embryo quality, blastocyst development) were significantly higher in T90 than T0 cycles. No T0 cycle resulted in an evolutive pregnancy. Conversely, in T90 cycles 29 singleton clinical pregnancies were obtained. No negative neonatal outcomes were recorded in newborns after antioxidant treatment. Diet supplementation of men who have had low fertilization rates in their previous ICSI cycles with a combination of myo-inositol, alpha-lipoic acid, folic acid, coenzyme Q10, zinc, selenium, betaine, and vitamins may improve semen reproductive potential and ICSI clinical outcome.

The Impact

Abstract Background: Iodine is an essential element for hormones synthesized by the human thyroid gland. Thyroid hormone deficiency affects all body tissues, including multiple endocrine changes that alter growth hormones, corticotrophin, glucocorticoids, and gonadal function. In many countries, subfertility is an important problem affecting about 10–15% of all couples trying to conceive. Male subfertile factors have accounted for 25–30% of all cases in their studies. The aim of this study was to study the correlation between urinary iodine concentration (UIC) and semen quality of fertile male in China.Methods: semen and urine samples were collected from males who attended a survey for the reproductive physiological constants of male and female in China. All participants were fertile and they should be free from diseases of male reproductive system and thyroid related diseases. We studied the correlation between UIC and semen quality parameters in fertile males and the effect of iodine concentration on male reproduction. Participants were divided into six groups based on UIC. We measured semen parameters and UIC. Semen parameters or time-to-pregnancy (TTP) were analyzed by Spearman correlation, linear regression and multivariable logistic regression. Results: 1089 men were recruited in the study. The mean and median age of participants were 27.46±0.12 and 27±3.88 years, respectively. UIC of 274 (25.16%) men was lower than the UIC of WHO recommended. UIC of 405 men located in the region of WHO recommended. 62.35% of them were not located in the optimal region. Semen concentration and total sperm count were found to decrease when UIC increases when the UIC≥100 ug/L. Conclusions: A male with deficient UIC or excessive UIC has more risk of lower semen quality such as sperm concentration and total sperm count. In addition, if a male with deficient UIC or excessive UIC, his wife has longer TTP than the males who had normal UIC. Deficient UIC associated with lower semen quality and TTP than excessive UIC.

Selection Of

The guinea pig, as a livestock species, is still developing and growing throughout Peru and neighboring countries, as reflected by its increasing export since 2000. However, the selection of proven fertile males is tedious due to the absence of seminal parameter standards and the lack of safe semen collection techniques. Thus, pregnancy detection or live births are required for males’ selection. The purpose of this study was to describe the qualitative and quantitative semen parameters of fertile guinea pig males, to set reference values, and to validate a novel electroejaculation technique for the species. Semen was collected at weekly intervals from sixteen fertile males. Four transrectal electroejaculations were performed per male with 95% successful collections, yielding 39 viable semen samples. Seminal characteristics were as follows: pH 7.0 ± 0.13; ejaculate volume 0.67 ± 0.55 mL; sperm motility 90.81 ± 6.64%; sperm concentration 36.7 ± 28.41 × 106 sperm/mL; sperm count 20.09 ± 17.56 × 106 sperm/ejaculate; percentage of abnormal morphology 18.26 ± 8.52%; and percentage ubiquitinated spermatozoa 5.57 ± 6.28%. These values will serve as a reference to detect best breeding and infertile males rapidly. The described techniques are reproducible by commercial producers.

Abstract Background The aim of this study was to provide information on the semen quality pattern of infertile men and age thresholds for semen parameters in China. Methods This was a retrospective cross-sectional study investigating 71,623 infertile men from the Reproductive and Genetic Hospital of CITIC Xiangya in Hunan, China, from 2011 to 2017. The Kruskal-Wallis test, Mann-Kendall test, linear regression model and joinpoint regression were used. Results Although erratic changes were observed in the median semen parameters (sperm concentration 40.1–52.1 × 106/ml, total sperm count 117.8–153.1 × 106, sperm progressive motility 33.4–38.1%) during the 7 years of observation, no significant decrease in semen quality was found, and 47.88% of infertile men showed normal semen parameters according to the World Health Organization (WHO) criteria. According to the joinpoint regression analysis, sperm progressive motility appeared to decrease earlier than the sperm concentration and total sperm count (at 28, 58, and 42 years of age, respectively). Conclusions There is no evidence of a deterioration in semen quality among infertile men in Hunan, China. Semen parameters decreased with increasing age, with turning points noted at different ages. Semen parameters are not absolute evidence for the assessment of male fertility potential. Therefore, we believe that, among semen parameters, the sperm concentration is the best predictor of fertility for ART, followed by motility. Decreased sperm motility may affect natural pregnancy, but it is not necessary for successful IVF.

ABSTRACT Background It is unknown which compounds in spermatozoa or seminal plasma may be involved in the regulation of sperm motility. Objectives The aim of this study was to investigate the effects of DHA (22:6n–3), vitamin E, and their probable interactions in men with asthenozoospermia. Methods A factorial, randomized, double-blind, placebo-controlled trial was conducted in infertility clinics in Tehran, Iran. The participants were idiopathic asthenozoospermic men aged 20–45 y, with normal endocrine function. Their concentration of spermatozoa and percentage of morphologically normal spermatozoa were equal to or above the lower reference limits, according to the fifth edition of the WHO guideline. Out of 717 men referred to the infertility clinics, 180 asthenozoospermic men were randomly assigned to 1 of 4 groups according to stratified blocked randomization by age and sperm concentration. Participants took daily 465 mg DHA plus 600 IU vitamin E (DE), 465 mg DHA plus placebo (DP), 600 IU vitamin E plus placebo (EP), or both placebo capsules (PP) for 12 wk. Sperm characteristics, oxidative stress of seminal plasma, serum and sperm membrane fatty acids, dietary intakes, anthropometric measurements, and physical activity were measured at baseline and after 12 wk. Results After the intervention, mean ± SD sperm progressive motility was greater in the DE group (27.9 ± 2.8) than in the DP (25.7 ± 3.4), EP (26.1 ± 2.8), and PP (25.8 ± 2.6) groups (P &lt; 0.05). Sperm count (P = 0.001) and concentration (P = 0.044) increased significantly in the DE group compared with the other 3 groups, whereas other semen parameters were not significantly different between the groups after the intervention. Serum concentrations of n–3 PUFAs were significantly higher in the DE and DP groups than in the EP and PP groups. Conclusions Combined DHA and vitamin E supplements led to increased sperm motility; however, no significant changes occurred in sperm morphology and vitality in asthenozoospermic men. This trial was registered at clinicaltrials.gov as NCT01846325.

Introduction: Premature ejaculation (PE) is one of the most common disorders in sexual intercourses among men and may occur for any man in any period of his life. PE results in some mental disorders such as anxiety, depression and marital disaffection and can have psychological impacts. The present study is aimed to investigate the effect of the abstinence time on the semen analysis parameters among men. Methods: The present cross-sectional study was conducted on a statistical population including 100 male patients referring to the urology clinic in Ali-Ibn-Abitaleb Hospital. Once included in the study, these individuals are divided into three groups with short-term abstinence (less than 2 days), mid-term abstinence (2-9 days), and long-term abstinence (more than 9 days). The patients, depending on the group to which they belonged, were asked to deliver their semen at the specified time to the laboratory in less than an hour. The obtained data were statistically analyzed in SPSS-22 software. Findings: The results of Pearson correlation and Spearman tests indicated a direct positive relationship between the abstinence time and the total number of sperms in the seminal fluid, concentration of the sperms in the seminal fluid, volume of the seminal fluid, sperm DNA fragmentation, reactive oxygen species in the seminal fluid, and pH of the seminal fluid.accordingly, the longer the abstinence time, the more the occurrence of these disorders. Also, the correlation test results showed that the abstinence time had an inverse relationship with motility and morphology of the sperms in the seminal fluid; accordingly, with elongation of the abstinence time, the motility (mobility) and morphology of the sperms in the seminal fluid were reduced. Conclusion: The researchers in the present work concluded the presence of a relationship between the abstinence time and the quality of the sperm parameters. Results of the present study showed that the abstinence time is significantly associated with the total sperm count, sperm concentration seminal fluid volume and pH.

Abstract Purpose: The length of sexual abstinence seems to influence sperm quality. However, few data on the relevance of abstinence time in pathological sperm samples are available. With our study, we look for associations of abstinence length and semen quality. Methods: We studied semen samples from 4423 men undergoing fertility evaluation. Sperm concentration, percentage of progressively motile spermatozoa, total motile sperm count, percentage of spermatozoa with normal morphology, were compared after each day and 0-2, 3-7 and >7 days of abstinence. Results: We found that a longer abstinence time was related to higher sperm concentration in normal semen samples (P<0.001) and in semen samples with any sperm pathology (P<0.001, P=0.004) with the exception of oligozoospermia (P=0.125). Longer abstinence time was also associated with significantly reduced progressive motility in normal samples (P<0.001) and in cases of teratozoospermia (P<0.001). In normal samples a higher percentage of sperm were morphologically normal after a shorter abstinence period (P=0.03); in oligoasthenoteratozoospermia (OAT) samples, this was the case after a longer abstinence period (P=0.013). Conclusion: A longer abstinence time is associated with higher sperm concentration, whereas sperm motility is optimal after shorter abstinence times; results on morphology are controversial. The recommendation on abstinence time needs to be adjusted in relation to the parameter that needs to be improved.
