RESUMO

Andrologists, cardiologists and diabetologists (and general practitioners) have the great opportunity to collaborate and find shared clinical workup for the benefit of a large number of men. Several evidence established a link between erectile dysfunction (ED), cardiovascular disease (CVD), diabetes, and metabolic syndrome. Not only these conditions share many risk factors and pathophysiological mechanisms but also an emerging paradigm indicates that ED is, in fact, an independent marker of cardiovascular disease risk, CV events and CV mortality. However, there is no consensus on the best cardiologic investigation in men with ED with no known CVD and, on the contrary, on what is the clinical and prognostic role of detecting ED during cardiovascular investigation and CVD risk assessment. Only vasculogenic ED, which represents the most common type of organic ED, indeed represents a harbinger of CVD, especially for younger patients, and might be diagnosed by dynamic penile color doppler ultrasonography, which represents a real cardiovascular imaging technique that give evidence on the presence of systemic endothelial dysfunction and atherosclerosis. Furthermore, assessment of glucose and lipid metabolism is warranted as first step workup in all ED patients, and diabetologists should ask their patients for erectile function, address ED patients to andrologists, and consider vasculogenic ED in the context of the cardiovascular and metabolic workup and in the context of diabetic complications. Sexual symptoms (and testosterone levels) should sound as harbinger for cardiovascular and metabolic investigation and cardiologists and diabetologists have the opportunity to have a symptom (erectile dysfunction) and a vascular test (penile color doppler) that help them in better management of patients, their comorbidities and complications.

RESUMO

This study describes a new method of microcentrifugation as an improved, viable, cost-effective option to the classical Cytospin apparatus to confirm azoospermia. Azoospermic semen samples were evaluated for cryptozoospermia by a centrifugation method similar to that of World Health Organization guidelines (2010; entire specimen centrifuged at 3000g for 15 min, and aliquots of the pellet examined). Then, if no sperm were detected, the pellet from that procedure was resuspended in culture medium, centrifuged (2000g for 15 min), and the entire pellet spread on a 4 X 6mm area of a slide and stained using the Christmas tree method (Nuclear-Fast solution and picric acid). The entire stained area was examined for the presence or absence of sperm. A total of 148 azoospermic samples (after standard WHO diagnosis) were included in the study and 21 samples (14.2%) were identified as sperm-positive. In all microcentrifugation slides, intact spermatozoa could be easily visualized against a clear background, with no cellular debris. This novel microcentrifugation technique is clearly a simple and effective method, with lower cost, increasing both sensitivity and specificity in confirming the absence or presence of spermatozoa in the ejaculate. It may represent a step forward of prognostic value to be introduced by andrology laboratories in the routine evaluation of patients with azoospermia in the initial semen analysis.

RESUMO

The introduction of the operative microscope for andrological surgery in the 1970s provided enhanced magnification and accuracy, unparalleled to any previous visual loop or magnification techniques. This technology revolutionized techniques for microsurgery in andrology. Today, we may be on the verge of a second such revolution by the incorporation of robotic assisted platforms for microsurgery in andrology. Robotic assisted microsurgery is being utilized to a greater degree in andrology and a number of other microsurgical fields, such as ophthalmology, hand surgery, plastics and reconstructive surgery. The potential advantages of robotic assisted platforms include elimination of tremor, improved stability, surgeon ergonomics, scalability of motion, multi-input visual interphases with up to three simultaneous visual views, enhanced magnification, and the ability to manipulate three surgical instruments and cameras simultaneously. This review paper begins with the historical development of robotic microsurgery. It then provides an in-depth presentation of the technique and outcomes of common robotic microsurgical andrological procedures, such as vasectomy reversal, subinguinal varicocelectomy, targeted spermatic cord denervation (for chronic orchialgia) and robotic assisted microsurgical testicular sperm extraction (microTESE).

RESUMO

BACKGROUND: Sperm morphology is known to correlate with the probability of conception both in vitro and in vivo, but the assessment of sperm morphology in the laboratory remains problematic. The 4th edition (1999) of the World Health Organization (WHO) Laboratory Manual has attempted to improve matters by giving rigorous recommendations regarding sperm morphology assessment. However, it is unknown how well these recommendations have been implemented in practice. METHODS: A survey of the methods used to undertake the assessment of sperm morphology during semen analysis was undertaken in 37 laboratories in the UK. RESULTS: In total, only two laboratories (5%) were compliant with all current WHO guidelines regarding morphology assessment, including methods of staining and observation, classifying and sampling methods, and the participation in internal and external quality control programmes. CONCLUSION: These results illustrate an urgent need for education and training initiatives to encourage laboratories to become compliant with current WHO guidelines for sperm morphology assessment.
