RESUMO
Non-obstructive azoospermia (NOA) is found in up to 15% of infertile men. While several causes for NOA have been identified, the exact etiology remains unknown in many patients. Advances in assisted reproductive technology, including intracytoplasmic sperm injection (ICSI) and testicular sperm retrieval, have provided hope for these patients. This review summarizes the chances of success with ICSI for NOA patients and examines preoperative factors and laboratory techniques associated with positive outcomes. Furthermore, we reviewed possible consequences for offspring by the use of ICSI with testicular sperm retrieved from NOA patients and the interventions that could potentially mitigate risks. Testicular sperm retrieved from NOA patients may exhibit increased chromosomal abnormalities, and although lower fertilization and pregnancy rates are reported in NOA patients compared to other forms of infertility, the available evidence does not suggest a significant increase in miscarriage rate, congenital malformation, or developmental delay in their offspring compared to the offspring of patients with less severe forms of infertility or the offspring of fertile men. However, due to limited data, NOA patients should receive specialized reproductive care and personalized management. Counseling of NOA patients is essential before initiating any fertility enhancement treatment not only to mitigate health risks associated with NOA but also to enhance the chances of successful outcomes and minimize possible risks to the offspring.
RESUMO
Background: Studies exploring the effect of COVID-19 on male reproductive system suggest a detrimental association, however with conflicting results. The aim of this study was to assess the association between COVID-19 infection and male reproductive potential including hormone profiles and semen parameters. Methods: This prospective cohort study included 48 patients with confirmed COVID-19 infection. Patients were subdivided into an asymptomatic group (n = 30) and a group with COVID-19 symptoms (n = 18). Serum hormone levels including testosterone, LH, FSH and estradiol were collected during active infection (baseline, time 0), and at 3 and 6 months following COVID-19 infection. Semen samples (basic semen analysis and oxidation reduction potential) were examined at 3 and 6 months following infection. Student and paired-t tests were used to compare continuous variables between the study groups and across the studied time intervals, respectively. Multivariate binary logistic regression analysis was performed to explore predictors for COVID-19 symptoms during active infection. Results: Patients with COVID-19 symptoms were significantly older (p = 0.02) and had significantly lower serum testosterone levels (p = 0.01) and significantly higher LH: testosterone ratio (p = 0.01) than asymptomatic patients. Multivariate analysis revealed older age (OR = 1.18, p = 0.03) and lower serum testosterone level (OR = 0.8, p = 0.03) as independent predictors of symptomatic COVID-19 infection. Significant increase in testosterone (p < 0.001 for both) and decrease in LH (p = 0.02, p = 0.007) and LH: testosterone (p = 0.02, p = 0.005) levels were observed at 3 and 6 months in patients with COVID-19 symptoms. Asymptomatic patients demonstrated significant increase in testosterone (p = 0.02) and decrease in LH: testosterone (p = 0.04) levels only at 3 months following COVID-19 infection. No significant differences were observed between the two study groups with regards to the semen analysis results obtained at 3 or 6 months following COVID-19 infection. Conclusion: Significantly lower testosterone values are associated with worse disease severity among men with COVID-19 infection. This association appears to be temporary as a significant increase in testosterone levels are witnessed as early as 3 months following recovery. No significant detrimental effect for COVID-19 infection on testicular sperm production is found in this patient population.
RESUMO
In recent years, there has been a growing interest in identifying subcellular causes of male infertility, and sperm DNA fragmentation (SDF) research has been at the forefront of this focus. DNA damage can occur during spermatogenesis due to faulty chromatin compaction or excessive abortive apoptosis. It can also happen as sperm transit through the genital tract, often induced by oxidative stress. There are several methods for SDF testing, with the sperm chromatin structure assay, terminal deoxynucleotidyl transferase d-UTI nick end labeling (TUNEL) assay, comet assay, and sperm chromatin dispersion test being the most commonly used. Numerous studies strongly support the negative impact of SDF on male fertility potential. DNA damage has been linked to various morphological and functional sperm abnormalities, ultimately affecting natural conception and assisted reproductive technology outcomes. This evidence-based review aims to explore how SDF influences male reproduction and provide insights into available therapeutic options to minimize its detrimental impact.

Introduction: Chronic pelvic pain syndrome (CPPS) is a frequent urological diagnosis that affects men's quality of life. Extracorporeal shockwave therapy (ESWT) is a recent treatment option for patients with CPPS. We evaluated ESWT's short and long - term efficacy in managing CPPS. Methods: This prospective self-controlled study included 75 patients diagnosed with CPPS at our tertiary pelvic pain clinic between January 2017-June 2019. Patients were referred for ESWT and received four sessions one week apart. The National Institute for Health - Chronic Prostatitis Symptom Index (NIH - CPSI) questionnaire was used to assess patients' symptom severity before starting therapy and at 0, 12 and 26 weeks after completing ESWT. Demographics, clinical data and complications were also recorded. Results: Patients' mean age was 37.9 ± 8.6 years, and mean duration of symptoms was 5 ± 4.5 years. Compared to pre-treatment scores, all patients exhibited improvements across all NIH - CPSI domains directly after completing ESWT (week 0 post-treatment), with a mean difference improvement of 9.26 ± 5.7, 5.2 ± 3.4, 1.19 ± 2.18 and 2.88 ± 2.46 points in the total, pain, urinary symptoms, and quality-of-life scores respectively. At 12 weeks after completing ESWT, 80.9% of patients reported improvements, with mean difference improvement of 8.07 ± 7.56, 4.55 ± 4.6, 0.76 ± 2.48, 2.85 ± 2.78 in the total, pain, urinary symptoms, and quality-of-life scores respectively. Again, none of the patients developed any treatment-related complications. At 26 weeks after completing ESWT, 82.4% of patients reported improvements, with mean difference improvement of 8.29 ± 7.7%, 4.92 ± 4.69, 0.75 ± 2.96, 2.5 ± 3.0 in total, pain, urinary symptoms, and quality-of-life scores respectively. None of the patients developed treatment-related complications. Conclusions: ESWT is a safe and effective treatment modality for patients with CPPS, with short-term improvement in total, pain, urinary symptom, and quality-of-life scores; and long-term improvement in total, pain, and quality-of-life scores.
RESUMO
Background: Few studies assessed the relationships between BMI and post varicocelectomy semen quality and fertility potential and they reported inconsistent findings. Objective: To assess the association of BMI with semen parameters and reproductive hormones before and after microsurgical varicocelectomy. Materials and Methods: Retrospective chart review in a tertiary infertility center. Of 1170 patients with clinical varicocele during the study period (8 years), 813 patients were eligible and included. Patients were grouped into: Group A (kg/m2, n = 251 patients), B (BMI 25-29.9 kg/m2, n = 289), C (BMI 30-34.9 kg/m2, n = 183) and D (kg/m2, n = 90). Clinical data, semen parameters, sperm DNA fragmentation and hormonal profile were collected before and 3 months after microsurgical varicocelectomy. Results: Patients' mean age was 35.87 ± 8.17 years. Higher-grade varicocele was significantly more prevalent in the lower BMI groups. BMI was significantly negatively correlated with preoperative sperm concentration, total motility progressive motility and total motile sperm count. Pre-operatively, sperm concentration, total motility, progressive motility and total motile sperm count showed significant differences between BMI groups, where higher BMI (Groups C and D) exhibited the poorest semen parameters. Postoperatively, all groups showed significant improvement in sperm concentration compared with pre-operative values. However, total and progressive motility were significantly improved in Groups A, B and C, while in Group D (highest BMI), total motility improved clinically but not statistically, progressive motility did not display improvement, and total motile sperm count was significantly improved only in Groups B and C. Postoperatively, mean improvements in semen parameters across the BMI groups were not significantly different, except for morphology, which improved significantly more in the less obese patients. Conclusion: For infertile patients with clinical varicocele undergoing micro-surgical varicocelectomy, BMI appears not to impact the improvements across most of the semen parameters and hormones. The procedure might improve the fertility potential.
RESUMO
Background: To date, no previous research assessed the bibliometrics of men's sexual and reproductive healthcare (SRHC) across Arab countries. This study appraised the current standing of men's SRHC research in the MENA (Middle East and North Africa) region. Methods: We performed a bibliometric analysis to assess qualitatively and quantitatively the peer-reviewed articles published from Arab countries from inception to 2022. In addition, we conducted a visualization analysis, and assessed outputs, trends, shortcomings and hotspots over the given time period. Results: There was a generally low numbers of publications, 98 studies were identified, all with cross-sectional design, and two thirds explored prevention and control of HIV/other STDs. Studies were published in 71 journals, of which the Eastern Mediterranean Health Journal, Journal of Egyptian Public Health Association, AIDS Care and BMC public health were most common. The Journal of Adolescent Health, Fertility Sterility and Journal of Cancer Survivorship were among the highest IF ranking. Publishers were commonly USA or UK-based, median journal IF was 2.09, and five articles were in journals of IF > 4. Saudi Arabia had the highest published output followed by Egypt, Jordan and Lebanon, while 10 Arab countries had no publications on the topic. Corresponding authors expertise fields were most commonly public health, infectious diseases and family medicine). Collaborations in-between MENA countries were notably low. Conclusions: There is general paucity of published outputs on SRHC. More research across MENA is needed, with more inter-MENA collaborations, and with inclusion of countries that currently have no outputs on SRHC. In order to accomplish such goals, R&D funding and capacity building are required. Research and published outputs should address SRHC burdens.
RESUMO
BACKGROUND: Hypogonadism in older men is often considered as late onset hypogonadism. However, this clinical condition results from primary testicular failure which could be of genetic origin with Klinefelter syndrome being the most common chromosomal abnormality associated with it. CASE PRESENTATION: We report a heterogeneous group of cases who were diagnosed with hypergonadotropic hypogonadism in their adulthood and were found to have rare chromosomal aberrations. All were elderly men (in their 70 s and 80 s) for whom the diagnosis was made during the evaluation of incidental symptoms suggestive of endocrinopathy. The first had hyponatremia; the other two had gynaecomastia and features of hypogonadism noted during admission for various acute medical problems. With respect to their genetic results; the first had a male karyotype with balanced reciprocal translocation between the long arm of chromosome 4 and the short arm of chromosome 7. The second case had a male karotype with one normal X chromosome and an isochrome for the short arm of the Y chromosome. The third case was an XX male with unbalanced translocation between the X & Y chromosomes with retention of the SRY locus. CONCLUSION: Hypergonadotrophic hypogonadism in the elderly, may be due to chromosomal aberrations, resulting in heterogeneous and diverse clinical phenotypes. Vigilance must be exercised when seeing cases with subtle clinical findings. This report suggests that in selected cases of adult hypergonadotropic hypogonadism, chromosomal analysis may be indicated.

BACKGROUND: No study appraised the knowledge gaps and factors impacting men's sexual and reproductive health (SRH) in MENA (Middle East and North Africa). The current scoping review undertook this task. METHODS: We searched PubMed and Web of Science (WoS) electronic databases for original articles on men's SRH published from MENA. Data was extracted from the selected articles and mapped out employing the WHO framework for operationalising SRH. Analyses and data synthesis identified the factors impacting on men's experiences of and access to SRH. RESULTS: A total of 98 articles met the inclusion criteria and were included in the analysis. The majority of studies focused on HIV and other sexually transmissible infections (67%); followed by comprehensive education and information (10%); contraception counselling/provision (9%); sexual function and psychosexual counselling (5%); fertility care (8%); and gender-based violence prevention, support/care (1%). There were no studies on antenatal/intrapartum/postnatal care and on safe abortion care (0% for both). Conceptually, there was lack of knowledge of the different domains of men's SRH, with negative attitudes, and many misconceptions; as well as a deficiency of health system policies, strategies and interventions for SRH. CONCLUSION: Men's SRH is not sufficiently prioritized. We observed five 'paradoxes': strong focus on HIV/AIDS, when MENA has low prevalence of HIV; weak focus on both fertility and sexual dysfunctions, despite their high prevalence in MENA; no publications on men's involvement in sexual gender-based violence, despite its frequency across MENA; no studies of men's involvement in antenatal/intrapartum/postnatal care, despite the international literature valuing such involvement; and, many studies identifying lack of SRH knowledge, but no publications on policies and strategies addressing such shortcoming. These 'mismatches' suggest the necessity for efforts to enhance the education of the general population and healthcare workers, as well as improvements across MENA health systems, with future research examining their effects on men's SRH.

Objective: We appraised the reporting quality of abstracts of systematic reviews/meta-analyses (SR/MAs) published in one urology journal and explored associations between abstract characteristics and completeness of reporting. Methods: The Arab Journal of Urology (AJU) was searched for SR/MAs published between January 2011 and 31 May 2022. SR/MAs with structured abstract and quantitative synthesis were eligible. Two reviewers simultaneously together selected the SR/MAs by title, screened the abstracts, and included those based on inclusion/exclusion criteria. Data of a range of characteristics were extracted from each SR/MAs into a spreadsheet. To gauge completeness of reporting, the PRISMA-Abstract checklist (12 items) was used to appraise the extent to which abstracts adhered to the checklist. For each abstract, we computed item, section, and overall adherence. Chi-square and t-tests compared the adherence scores. Univariate and multivariate analyses identified the abstract characteristics associated with overall adherence. Results: In total, 66 SR/MAs published during the examined period; 62 were included. Partial reporting was not uncommon. In terms of adherence to the 12 PRISMA-A items were: two items exhibited 100% adherence (title, objectives); five items had 80% to <100% adherence (interpretation, included studies, synthesis of results, eligibility criteria, and information sources); two items displayed 40% to <80% adherence (description of the effect, strengths/limitations of evidence); and three items had adherence that fell between 0% and 1.6% (risk of bias, funding/conflict of interest, registration). Multivariable regression revealed two independent predictors of overall adherence: single-country authorship (i.e. no collaboration) was associated with higher overall adherence (P = 0.046); and abstracts from South America were associated with lower overall adherence (P = 0.04). Conclusion: This study is the first to appraise abstracts of SR/MAs in urology. For high-quality abstracts, improvements are needed in the quality of reporting. Adoption/better adherence to PRISMA-A checklist by editors/authors could improve the reporting quality and completeness of SR/MAs abstracts.
RESUMO
PURPOSE: COVID-19 frequently affects the kidneys with symptoms ranging from mild proteinuria to progressive acute kidney injury. This prospective study aimed to assess the short- and long-term impact of asymptomatic and mild COVID-19 on the renal function of healthy young adults, and to determine the correlation between viral load and kidney function among these patients. METHODS: This was a prospective cohort study conducted over a period of 6 months. Patients were followed-up at baseline, and then after 3 and 6 months, respectively. Real-time PCR cycle threshold (CT) was used to determine the viral load and disease activity. Patients were classified into two groups with either asymptomatic COVID-19 or mild pneumonia. The assessment parameters were variables that could directly or indirectly relate to the renal function. RESULTS: A total of 48 patients were included and evaluated. The majority of patients (62.5%) had asymptomatic COVID-19 disease. Patients with mild pneumonia had significantly higher serum creatinine (SCr) at the time of COVID-19 diagnosis (beta = 12.836, 95% CI = 2.405-23.268, P = 0.019), after 3 months (beta = 14.345, 95% CI = 1.149-27.542, P = 0.035), and after 6 months (beta = 14.100, 95% CI = 0.730-27.470, P = 0.040) compared to asymptomatic patients. Mild pneumonia was also significantly associated with lower serum albumin level at the time of COVID-19 diagnosis (beta = - 6.317, 95% CI = - 9.448-- 3.185, P < 0.001). CONCLUSION: Mild COVID-19 is associated with mild renal involvement without AKI. Changes in the renal function appear to be related to reduced creatinine clearance and possible albumin leakage in the acute phase of the disease. The reduction in creatinine clearance is not predicted by viral load, and it appears to be a long-term effect of the disease that can last for at least 6 months.

Purpose: To systematically review the evidence on the association between sexually transmitted infections (STIs) and male infertility. We sought to answer two questions: Are STIs significantly associated with detrimental changes in semen parameters?; and, is the prevalence of STIs significantly higher in infertile than fertile men? Materials and methods: PubMed, Scopus and Google Scholar databases were searched (inceptionMarch 2023) following the PRISMA guidelines. Identified original studies in English on the association between STIs and male infertility were included. Data was tabulated/described by pathogen, mechanisms of action, number of studies and their level of evidence. Results: Seventy out of 903 originally retrieved articles were included in this review. For the detrimental changes in semen parameters (first question), the evidence seems equivocal based on the nearly equal number of studies and similar levels of evidence. The only exception was for Ureaplasma, where the number of studies and levels of evidence supported an association with male infertility. Pertaining to a significantly higher prevalence of STI among infertile compared to fertile men (second question), evidence was insufficient to support/deny a significant association. The two exceptions were Ureaplasma and Mycoplasma, where the number of studies and evidence levels were in favour of an association with male infertility. Conclusions: Generally, the relationship between STIs and male infertility remains to be uncovered. Our appraisal of the overall state of this relationship shows that the evidence base leaves much to be desired. The exceptions are Ureaplasma and Mycoplasma, where the evidence convincingly suggests their associations with infertility in men.
RESUMO
Genitourinary anomalies constitute a large proportion of congenital malformations. However seminal tract anomalies, particularly ejaculatory duct (ED) anomalies are very rare and little information exists on the topic. We are reporting a very rare case of bilateral ectopic EDs opening in the bladder trigone in a 33-year-old gentleman presenting for evaluation for primary infertility. The patient's semen analysis showed low-ejaculate-volume, fructose negative, acidic pH and azoospermia. His hormonal profile was normal. Cystoscopy revealed an empty posterior urethra, and the verumontanum and the openings of the EDs could not be identified in the posterior urethra. The ED openings were found inside the bladder trigone. Vasography combined with cystoscopy confirmed the opening of the ED in the trigone following Intra-vasal injection of methylene blue. Our patient had a successful intracytoplasmic sperm injection using testicular spermatozoa that resulted in a healthy baby boy. We also did a formal literature review through PUBMED, MEDLINE and Google Scholar with the search term (ectopic ED). Search results were filtered to exclude vas deferens ectopia. Our literature search revealed five studies comprising 24 patients with ectopic EDs. Mean age at diagnosis was 29.88 ± 12.88 years. The most common presenting symptom was hemospermia. The ectopic EDs most commonly opened in a midline cyst (21 cases), bladder trigone (1 case), or bladder neck (1 case). The most common management used for symptomatic patients with ectopic EDs opening in the midline cyst was through transurethral fenestration. In conclusion, ectopic ED openings in the bladder trigone are very rare. Management varies by case depending on the presentation, anatomy of underlying anomaly, associated complication/s and desire for fertility.

Recurrence following varicocelectomy is an important cause of treatment failure and persistence of subnormal semen parameters. This original study was combined with a systemic review and meta-analysis aiming to evaluate the efficacy of redo varicocelectomy on male fertility potential and pregnancy outcome. The retrospective study included 32 patients who underwent microsurgical subinguinal varicocelectomy for patients with recurrent varicocele. Changes in semen parameters and hormone profiles before and after surgery were compared. The literature review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and included seven articles in addition to our original report. Results of the original study revealed statistically significant improvements in sperm concentration, progressive motility, total motile sperm count and normal morphology following redo varicocelectomy. The meta-analysis results echoed those reported in our original study and depicted significant improvements in sperm concentration (mean difference [MD] = +20.281 million/ml, p < 0.001), total motility (MD = +9.659%, p = 0.001), total motile sperm count (MD = +23.258 million sperm, p < 0.001) and normal morphology (MD = +4.460%, p < 0.001). Overall pregnancy outcome was reported in seven studies with a rate of 34.6%. No significant changes were noted in any of the collected hormone results both in this original report and in the meta-analysis. In conclusion, redo varicocelectomy has a beneficial role on male fertility potential and can be offered for men with recurrent varicocele as directed by their individual clinical condition.

OBJECTIVE: To evaluate the effectiveness of UPOINT based multimodal treatment on patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and determine factors that could be associated with clinical improvement. METHODS: A retrospective study was conducted in Doha, Qatar including patients with CP/CPPS from the Middle East and North Africa. The UPOINT phenotyping system was used to classify patients and guide their multimodal therapy. NIH-CPSI scores were computed initially and after 3 months of treatment, and predictors of clinical improvement were assessed. RESULTS: The total NIH-CPSI improved significantly with a mean reduction of 8.21 after 3 months of treatment (P < .001). 66.2% of patients had a clinical improvement demonstrated as a total NIH-CPSI score reduction by at least 6 points after 3 months of treatment. No significant association was found between clinical improvement, and extent of pain (ORa = 1.198, 95% CI 0.392-3.662, P = .751), initial total NIH-CPSI (ORa = 0.983, 95% CI 0.886-1.089, P = .738), number of positive UPOINT domains (ORa = 0.871, 95% CI 0.451-1.681, P = .681), and number of prescribed therapies (ORa = 1.118, 95% CI 0.699-1.789, P = .641). CONCLUSION: UPOINT phenotyping and directed therapy is associated with an important improvement in the CP/CPPS. Therapeutic response does not appear to related to age or ethnicity. Clinical improvement is also not predicted by initial extent and severity of the disease, whether relating to NIH-CPSI or the number of positive UPOINT phenotypes, neither to the number of therapies involved in the multimodal treatment strategy.

Introduction: Metabolic Age (MetAge) and body composition analysis may reflect an individual's metabolic status, which is believed to influence male sexual and gonadal functions. Although erectile dysfunction (ED) and hypogonadism are increasingly prevalent with age, they are also detected among younger men. This study aims to assess the impact of MetAge and body composition on male sexual and gonadal status overall, and particularly in men younger than 40 years of age. Methods: This was a cross-sectional study of 90 male healthcare workers, between the ages of 18-55, randomly selected based on their corporation numbers. In addition to Bioelectric Impedance Analysis, subjects were requested to fill the International Index of Erectile Function questionnaire (IIEF-5) and to provide an early morning serum testosterone (T) sample. Results: The mean participants' age was 39.4 ± 9.4 years, MetAge was 45.54 ± 10.35 years, serum T level was 13.68 ± 4.49 nmol/L and BMI was 28.8 ± 4.7 kg/m2. Significant negative correlations were obtained between serum T, MetAge, body weight and fat composition. Significant negative correlations between the IIEF-5 score, MetAge, and fat composition, were only reported in subjects <40 years of age. Significantly lower T levels (p=0.002), significantly older MetAge (p=0.034), and higher BMI (p=0.044) and degree of obesity (p=0.042) were observed in participants <40 years with erectile dysfunction (ED) compared to their counterparts without ED. Discussion: MetAge and body composition parameters significantly impact the androgenic state. ED in men <40 years is associated with lower T levels, older MetAge and higher BMI and degree of obesity.

To identify the most prevalent chromosomal abnormalities in patients with non-obstructive azoospermia (NOA), consolidate their surgical sperm retrieval (SSR) rates and determine the significant predictors of positive SSR in this patient population. A systematic review and meta-analysis were performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Fifty-three studies including 2965 patients were identified through searching the PubMed database. Klinefelter Syndrome (KS) was the most prevalent chromosomal abnormality reported in 2239 cases (75.5%). Azoospermia factor c (AZFc) microdeletions were the second most common (18.6%), but men with these deletions had higher SSR rates than patients with KS (41.95% with AZFc vs. 38.63% with KS). When examining predictors of SSR in KS patients, younger age was a significant predictor of positive SSR in patients undergoing microsurgical testicular sperm extraction (micro-TESE). Higher testosterone was a favourable predictor in those undergoing micro-TESE and conventional TESE. Lower luteinizing hormone (LH) and follicular stimulating hormone (FSH) values were significantly associated with positive SSR with testicular sperm aspiration (TESA). No parameter predicted SSR rates in patients with AZFc microdeletions. Overall, genetic abnormalities have significant implications on SSR success in patients with NOA.

Semen analysis is the first, and frequently, the only step in the evaluation of male fertility. Although the laboratory procedures are conducted according to the World Health Organization (WHO) guidelines, semen analysis and especially sperm morphology assessment is very difficult to standardize and obtain reproducible results. This is mainly due to the highly subjective nature of their evaluation. ICSI is the choice of treatment when sperm morphology is severely abnormal (teratozoospermic). Hence, the standardization of laboratory protocols for sperm morphology evaluation represents a fundamental step to ensure reliable, accurate and consistent laboratory results that avoid misdiagnoses and inadequate treatment of the infertile patient. This article aims to promote standardized laboratory procedures for an accurate evaluation of sperm morphology, including the establishment of quality control and quality assurance policies. Additionally, the clinical importance of sperm morphology results in assisted reproductive outcomes is discussed, along with the clinical management of teratozoospermic patients.
RESUMO
Semen analysis is a basic test for evaluating male fertility potential, as it plays an essential role in driving the future management and treatment of infertility in couples. Manual semen analysis includes the evaluation of both macroscopic and microscopic parameters, whereas automated semen analysis is conducted through a computer-aided sperm analysis system and can include additional parameters that are not evaluated by manual analysis. Both quality control (QC) and quality assurance (QA) are important to ensure reproducible results for semen analysis, and represent fundamental checks and balances of all stages (pre-analytical, analytical, and post-analytical) of semen analysis. To ensure accuracy and precision, the laboratory technicians' performance should be evaluated biannually. This narrative review aims to describe standardized laboratory procedures for an accurate assessment of semen parameters that incorporate both QC and QA practices.
RESUMO
OBJECTIVE: : To examine the effect of paternal age on intracytoplasmic sperm injection (ICSI) outcomes in unexplained infertility. SUBJECTS AND METHODS: : This retrospective study, done at the Hamad Medical Corporation, Doha, Qatar screened infertile couples who underwent ICSI between 2014 and 2019 for the inclusion and exclusion criteria defining 'unexplained infertility'. Couples recruited were allocated into two groups: Group A (paternal age <35 years) and Group B (paternal age ≥35 years). Baseline characteristics, investigations including semen and advanced sperm function tests and ICSI records were compared for primary outcomes such as fertilisation, cleavage, clinical pregnancy, miscarriage and live birth; and secondary outcomes such as semen parameters and advanced sperm functions (DNA fragmentation index and oxidation reduction potential). RESULTS: : We found that final pregnancy outcomes including clinical pregnancy rate (P = 0.231), live-birth rate (P = 0.143), and miscarriage rates (P = 0.466) were not significantly different between the two age groups. Normal fertilisation (P = 0.01) and cleavage rate after ICSI (P = 0.001) were statistically significant when the age groups were compared. Also, normal sperm morphology was found to be significantly different (P = 0.041). CONCLUSIONS: : Advanced paternal age affects sperm morphology, fertilisation and embryo cleavage in ICSI but does not appear to affect clinical pregnancy, miscarriage or live-birth rates. ICSI appears to be a valid fertility treatment option in advancing paternal age.
