An Open Prospective Study on Whether Intracytoplasmic Morphologically Selected Sperm Injection (IMSI) Offers a Better Outcome Than Conventional Intracytoplasmic Sperm Injection (ICSI)

Objective

To differentiate the in vitro fertilization (IVF) outcomes between the two procedures, intracytoplasmic morphologically selected sperm injection (IMSI) and intracytoplasmic sperm injection (ICSI) in terms of relation to chemical pregnancy percentage, clinical pregnancy, live birth, miscarriage, and fertilization rates, respectively.

Patients and methods

This Open Prospective clinical trial was conducted during the period between Jan 2016 and Dec 2017 at one IVF unit. A total of 446 ICSI cycles and 79 IMSI cycles were conducted. Females were divided into four subgroups according to age.

Results

The study involved 525 couples (446 first trial ICSI cycles) and (79 first trial IMSI cycles). ICSI was statistically better than the IMSI in relation to the chemical pregnancy, clinical pregnancy (CPR), live birth (LBR), and fertilization rates, respectively (p < 0.05). However, there were no statistically significant differences between the ICSI and IMSI in relation to the miscarriage rate. There were statistically significant differences favoring ICSI in all subgroups except 35-37, in relation to chemical pregnancy; and in the 38-40 and >40 subgroups in relation to CPR. There were no statistically significant differences in these subgroups regarding the live birth, miscarriage, or fertilization rates.

Conclusions

This study showed that IMSI is not superior to conventional ICSI at the first attempt. Based on the findings in this study, we would not advise couples to choose IMSI at their first treatment attempt.

Triage of urology service to cope with COVID-19 pandemic: A single institution study

Almost a year ago, no one has ever heard of COVID-19 but now, every individual in the world is familiar with this term. It is far from over and yet, it has affected every aspect of human life. The Department of Urology at King's College Hospital London provides all types of urology care ranging from benign to cancer treatments to the community. However, this service was badly affected by COVID-19. Policies were made by the experts in the field to reduce patient traffic in the hospital and at the same time, attempting to ensure appropriate and timely treatment was provided to patients suffering from urological conditions requiring urgent attention. In this article, we discuss the triage guidelines set up at our centre. Treatments for benign conditions such as kidney stones were delayed for 3-6 months. For the first time, telephone and video clinics were setup to follow-up patients with benign conditions. Urological emergencies such as acute urinary retention and priapism were discharged from accidental and emergency department after treatment. Small T1 renal cancers were put on surveillance, whereas T2 and T3 renal cancers were offered nephrectomy at a COVID-free specialized center. Transurethral removal of bladder tumor was offered only for solid or actively bleeding tumor. High risk prostate cancer patients were started on hormonal therapy and radiotherapy was only offered for spinal cord compression secondary to metastasis. Low and intermediate non-metastatic prostate cancers were placed on active surveillance. Patients with testicular tumor continued to have immediate inguinal orchidectomy. The multi-disciplinary meetings were done remotely using blue jeans software®. These steps not only strive to provide adequate and timely urology care to patients but also protect health care workers and prevent the spread of COVID-19.

A Review of the Management of Chronic Scrotal Pain

Chronic scrotal pain (CSP) is a common and poorly understood medical condition that significantly affects individuals' quality of life. Many patients seek evaluation and management of their symptoms from multiple physicians. Our review aims to address diagnostic modalities, clinical evaluation, and surgical and non-surgical management. We conducted a computerised detailed search of the PubMed, Medline, Embase and Cochrane databases for reports pertaining to CSP using the Medical Subject Headings keywords 'chronic scrotal pain', 'testicular pain' and 'orchialgia', and we included in the review those that fulfilled the inclusion (adult male with CSP presenting with the criteria of CSP ) and exclusion (extra-scrotal pain) criteria. After the direct causes of CSP were identified by reviewing the clinical evaluations (history taking and examination are mandatory) and the diagnostic evaluations (urine analysis is crucial and ultrasound can be helpful), the most-used medical and non-surgical treatments for CSP were tricyclic antidepressants (success rate of up to 66.6%) and spermatic block (success rate of more than 90%), and the most-used surgical procedure was microsurgical denervation of the spermatic cord (success rate of up to 70%). The evidence currently available remains rare and of low quality, making it difficult to strongly recommend individual treatment options. However, multimodal treatment modalities using physical therapy and psychotherapy may help patients and provide useful tools for coping with this condition. There are also useful non-surgical and surgical options for CSP that depend on the patient's state, the severity of the complaint and what options have already been tried.

Erosion of an intrauterine contraceptive device into the urinary bladder: A case report

Intrauterine contraceptive devices may rarely erode into the urinary bladder, usually shortly after insertion. This case report describes the presentation and management of a copper-bearing intrauterine device which had eroded into the bladder. The patient presented with dysuria, dyspareunia and groin pain. The device had been inserted 10 years previously following a termination of pregnancy. A bladder stone had formed on the arm of the T-shaped device. The calculus was successfully lasered transurethrally and the intrauterine device was removed transvaginally. A urinary catheter was left on free drainage for four weeks and a follow-up cystogram showed no leak. Most complications related to intrauterine devices occur within days or weeks of insertion but in this case the complications presented 10 years later.

Painful Ejaculation - An Ignored Symptom

The purpose of this review is to summarize the pathophysiology of ejaculation and look into prevalence, aetiology, diagnosis, and treatment of painful ejaculation. We carried out a comprehensive search of PubMed in order to look for literature on male painful ejaculation using keywords post-orgasmic pain, painful ejaculation, dysejaculation, odynorgasmia, post-orgasmic pain, or dysorgasmia. Painful ejaculation has an alarming prevalence throughout the world, between 1 to 25%. It has a detrimental effect on patients' quality of life as it reduces individual self-esteem and is associated with sexual dysfunction. Its aetiology includes simple infection or inflammation of the urinary tract, benign prostate hyperplasia, ejaculatory duct obstruction, post-radical prostatectomy and side effects of certain medications. Once reported, it should be investigations and treatments should be tailored according to the etiology. Both medical and surgical treatment is available depending on the cause of painful ejaculation. Due to the sensitive nature of its presentation, it is a symptom that can be identified best when specifically asked. Our understanding regarding painful ejaculation is very limited and only a few articles have revealed insight into this topic. Further research is required in order to set proper guidelines for diagnosis and treatment of painful ejaculation.

An analysis of the frequency of Y-chromosome microdeletions and the determination of a threshold sperm concentration for genetic testing in infertile men

OBJECTIVE

To describe the prevalence of Y-chromosome microdeletions in a multi-ethnic urban population in London, UK. To also determine predictive factors and a clinical threshold for genetic testing in men with Y chromosome microdeletions.

PATIENTS AND METHODS

A retrospective cohort study of 1473 men that were referred to a tertiary Andrology centre with male factor infertility between July 2004 and December 2016. All had a genetic evaluation, hormonal profile and 2 abnormal semen analyses. Those with abnormal examination findings also had targeted imaging performed.

RESULTS

The prevalence of microdeletions was 4% (n = 58) in this study. These microdeletions were partitioned into the following regions: Azoospermia factors (AZF); AZFc (75%), AZFb+c (13.8%), AZFb (6.9%), AZFa (1.7%), and partial AZFa (1.7%). A high follicle-stimulating hormone level (P < 0.001) and a low sperm concentration (P < 0.05) were both found to be significant predictors for the identification of a microdeletion. Testosterone level, luteinising hormone level and testicular volume did not predict the presence of a microdeletion. None of the men with an AZF microdeletion had a sperm concentration of >0.5 million/mL. Lowering the sperm concentration threshold to this level retained the high sensitivity (100%) and increased the specificity (31%). This would produce significant cost savings when compared to the European Academy of Andrology/European Molecular Genetics Quality Network and European Association of Urology guidelines. The surgical sperm retrieval (SSR) rate after microdissection testicular sperm extraction was 33.2% in men with AZFc microdeletion.

CONCLUSIONS

The prevalence of Y-chromosome microdeletions in infertile men appears to vary between populations and countries. A low sperm concentration was a predictive factor (P < 0.05) for identifying microdeletions in infertile males. A threshold for genetic testing of 0.5 million/mL would increase the specificity and lower the relative cost without adversely affecting the sensitivity. The rate of SSR was lower than that previously described in the literature.

Sleep disorders in patients with erectile dysfunction

OBJECTIVE

To assess the prevalence of obstructive sleep apnoea (OSA) in men presenting with erectile dysfunction (ED) at a single centre.

PATIENTS AND METHODS

All men attending a specialised andrology outpatient department with a new diagnosis of ED were included in this prospective study. All patients completed three questionnaires: the International Index of Erectile Function (IIEF) and two sleep questionnaires [the Obstructive Sleep Apnoea Screening questionnaire and the Insomnia Severity Index (ISI)]. Their ED management was subsequently undertaken in accordance with local and European guidelines. An OSA diagnosis was made based on a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire and those patients were referred for specialist management.

RESULTS

Between February and September 2016, 129 patients with ED completed the study questionnaires. In all, 71 patients (55%) had a score of ≥3 on the Obstructive Sleep Apnoea Screening questionnaire, indicating a need for specialist sleep referral. Men who scored ≥3 on the Obstructive Sleep Apnoea Screening questionnaire were significantly older (61.4 vs 46.5 years; P < 0.001) and had a significantly higher body mass index (29.4 vs 26.7 kg/m² ; P < 0.001) when compared to the control group (OSA score of <3). The sleep apnoea group (OSA score of ≥3) had significantly worse IIEF-ED scores (6.2 vs 9.1; P = 0.018) and ISI scores (7.9 vs 5.5; P = 0.061).

CONCLUSION

Men presenting to the andrology clinic with ED are at significant risk of having undiagnosed sleep disorders. This has serious adverse health consequences, as well as being associated with potential dangers at work and travel. The patient compliance was high with 78% completing all three questionnaires. It is feasible to screen this population for sleep disturbance and this should be part of the ED assessment.
