Abdel-Hamid, I. A., Andersson K. - E., Waldinger M. D., & Anis T. H. (2016).  Tramadol Abuse and Sexual Function.. Sexual medicine reviews. 4(3), 235-246. Abstract

INTRODUCTION: Tramadol exhibits an effect profile similar to that of opioid agonists, and tramadol abuse seems to be a problem for a number of countries. The relationship between tramadol and sexual function appears to be controversial. Men with premature ejaculation (PE) may benefit from taking tramadol off label; however, these patients live "on a knife's edge" and are exquisitely sensitive to develop other sexual dysfunctions.

AIM: To review the literature regarding the problem of tramadol abuse and its relationship with sexual function.

METHODS: We searched electronic databases from 1977 to September 2015, including PubMed MEDLINE, EMBASE, EBCSO Academic Search Complete, Cochrane Systematic Reviews Database, and GoogleScholar using the following key words: tramadol, sexual functions, and sexual dysfunction.

MAIN OUTCOME MEASURE: To define the supposed benefits and the potential risks of tramadol on different sexual functions including ejaculation, orgasm, erection, desire, and testosterone levels.

RESULTS: Although tramadol is thought to have low abuse and dependence potentials worldwide, its abuse has become a serious problem in many countries, particularly in the Middle East, Africa, and West Asia. The benefit of tramadol in PE was reported in 11 clinical trials, evaluated by 6 systematic reviews, 3 of which pooled data in a meta-analysis. The evidence base on erectile dysfunction, decreased libido, hypogonadism, anorgasmia, and risky sexual behaviors in patients abusing tramadol is inadequate.

CONCLUSIONS: Tramadol may offer a useful intervention for treating PE. As all primary studies had suffered from selection, allocation, performance, or assessment bias, additional rigorous well-designed controlled trials are warranted to further investigate the potential long-term risks of tramadol and to determine the safe and the effective minimum daily dose. Clinical research on drug abuse and sexual dysfunction is an emerging field. To date, small numbers of studies have been performed and further studies are warranted.

AIM: To assess the relation of reactive oxygen species (ROS) and antioxidants in the internal spermatic vein blood compared to the peripheral venous blood. METHODS: Sixty-eight infertile oligoasthenozoospemic patients associated with varicocele were investigated. During inguinal varicocelectomy, blood samples of internal spermatic as well as median cubital veins were withdrawn. Three ROS factors (malondialdehyde [MDA], hydrogen peroxide H(2)O(2), nitric oxide [NO]) and four antioxidants (superoxide dismutase [SOD], catalase [Cat], glutathione peroxidase [GPx] and vitamin C) were estimated in these blood samples. RESULTS: Mean levels of tested ROS factors were significantly higher in the internal spermatic venous blood compared to those in the peripheral one (mean+/-SD) (MDA 18.7+/-1.4 nmol/mL vs. 15.4+/-1.4 nmol/mL, H(2)O(2) 43.6+/-8.0 micromol/mL vs. 30.8+/-8.1 micromol/mL, NO 2.3+/-0.5 nmol/L vs. 1.6+/-0.4 nmol/L, P<0.01). Mean levels of tested antioxidants were significantly lower in the internal spermatic venous blood compared to those in the peripheral one (superoxide dismutase 1 690.7+/-130.0 U/mL vs. 1 818.5+/-143.0 U/mL, catalase 38.9+/-6.1 mol/L vs. 47.9+/-10.2 mol/L, GPx 20.4+/-8.1 U/mL vs. 23.0+/-8.4 U/mL, vitamin C 0.3+/-0.1 vs. 0.4+/-0.1 mg/dL, P<0.05). CONCLUSION: Internal spermatic venous blood of infertile male cases associated with varicocele demonstrated elevated levels of ROS and decreased levels of antioxidants compared to peripheral venous circulation.

Several theories have been advanced to explain the mechanisms by which varicocele impairs male fertility. These theories include scrotal hyperthermia, retrograde flow of adrenal or renal metabolites, Leydig cell dysfunction and hypoxia. Varicocele is reported to be associated with elevated reactive oxygen species (ROS) production in spermatozoa and diminished seminal plasma antioxidant activity. The aim of this study was to investigate whether surgical correction of varicocele might reduce ROS or increase the antioxidant capacity of seminal plasma from infertile patients with varicocele. The study group consisted of 68 infertile males, selected from patients scheduled for varicocelectomy at Cairo University Hospital during the year 1999. Seminal plasma levels of two ROS [malondialdehyde (MDA), hydrogen peroxide (H2O2)] and one ROS radical [nitric oxide (NO)] were estimated as well as six antioxidants [superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), vitamin C (Vit C), vitamin E (Vit E), albumin) on the day prior to varicocelectomy. For comparison, the same parameters were measured again 3 and 6 months post-operatively. A statistically significant reduction in the 3 month post-operative levels of MDA, H2O2 and NO was observed when compared with the pre-operative values. A further significant reduction took place during the following 3 months. Four of the six antioxidants tested (SOD, CAT, GPx, and Vit C) showed a significant increase in seminal levels when comparing 3-month post-operative with pre-operative values. A further significant increase of the four antioxidant levels took place during the following 3 months. No significant change in the level of seminal plasma albumen took place during the first 3 months after varicocelectomy, however, a significant increase was noted during the next 3 months. In contrast to other antioxidants, seminal plasma levels of Vit E showed a significant decrease when comparing 3-month post-operative with pre-operative values. A further significant decrease took place during the following 3 months. It is concluded that varicocelectomy reduces ROS levels and increases antioxidant activity of seminal plasma from infertile men with varicocele.

The aim of this study was to assess seminal reactive oxygen species (ROS)-antioxidants relationship in fertile and infertile men with and without varicocele. One hundred and seventy six males were studied; fertile healthy volunteers (n = 45), fertile men with varicocele (n = 45), infertile oligoasthenozoospermia (OA, n = 44) without varicocele and infertile OA with varicocele (n = 42). In their seminal plasma, two ROS parameters (malondialdehyde, hydrogen peroxide) and five antioxidants (superoxide dismutase, catalase, glutathione peroxidase, vitaminE, vitaminC) were estimated. Compared with fertile healthy men, in all other studied groups, estimated seminal ROS were significantly higher and estimated antioxidants were significantly lower. Infertile men with varicocele showed the same relationship as infertile men without varicocele. Sperm concentration, total sperm motility as well as sperm normal forms were negatively correlated with seminal malondialdehyde and were positively correlated with vitaminC. It is concluded that varicocele has an oxidative stress (OS) in fertile normozoospermic bearing conditions. This may allow understanding that, within men with varicocele, there is a threshold value of OS over which male fertility may be impaired.

This work aimed to assess seminal plasma reactive oxygen species (ROS)-antioxidants relationship with varicocele grade in infertile men with oligoasthenoteratozoospermia (OAT). The study included 89 infertile OAT men with varicocele divided into grade I (n = 22) and grade II (n = 43), grade III (n = 24) and compared with 20 healthy fertile controls. In their seminal plasma, two ROS parameters (malondialdehyde [MDA], hydrogen peroxide [H(2) O(2) ]) and four antioxidants (superoxide dismutase [SOD], catalase [Cat], glutathione peroxidase [GPx], vit.C) were estimated. There was significant increase in seminal MDA, H(2) O(2) and significant decrease in seminal SOD, Cat, GPx, vit.C in varicocele-associated OAT cases when compared with the controls. Compared with grade I cases, varicocele cases with grades II, III demonstrated significant increase in estimated seminal MDA, H(2) O(2) and significant decrease in seminal SOD, Cat, GPx, vit.C. It is concluded that seminal oxidative stress (OS) is related to increased varicocele grade in infertile OAT men associated with varicocele.

INTRODUCTION: Erectile dysfunction (ED) is common and considered to be predominantly of vascular origin. AIM: To evaluate the link between ED and coronary artery disease (CAD) and provide a consensus report regarding evaluation and management. METHODS: A committee of eight experts from six countries was convened to review the worldwide literature concerning ED and CAD and provide a guideline for management. MAIN OUTCOME MEASURE: Expert opinion was based on grading the evidence-based medical literature, widespread internal committee discussion, public presentation, and debate. RESULTS: ED and CAD frequently coexist. Between 50-70% of men with CAD have ED. ED can arise before CAD is symptomatic with a time window of 3-5 years. ED and CAD share the same risk factors, and endothelial dysfunction is the common denominator. Treating ED in cardiac patients is safe, provided that their risks are properly evaluated. CONCLUSION: ED is a marker for silent CAD that needs to be excluded. Men with CAD frequently have ED that can be treated safely following guidelines.

The aim of this study is to evaluate the effectiveness of short-term sildenafil use in the management of unconsummated marriages diagnosed to be mainly psychogenic in origin. This retrospective study included 35 patients evaluated within an Andrology clinic. Patients underwent a complete medical and sexual history as well as a focused physical examination. Investigations were ordered as necessary following a goal-directed approach. Education about the male and female genital anatomy and the sexual response cycle was carried out, as well as a detailed explanation about the concepts of performance anxiety, vaginismus and the mode of action of sildenafil. Sildenafil on demand therapy was initiated for 1 month and the duration extended as needed. Of 35 patients included in our study, 32 (91%) were able to achieve vaginal intromission and perform sexually. In all, 23 patients needed the sildenafil (66%) for less than 1 month, five (14%) for up to 3 months and four (11%) for more than 3 months. Three patients (9%) were unsuccessful. Treatment failures were managed by intracavernous injection therapy, combined with psychosexual therapy, depending on the cause. We conclude sildenafil use is effective as a short-term treatment option in the management of unconsummated marriages.

OBJECTIVES: To compare and assess objectively the postoperative outcome parameters of both microsurgical subinguinal artery sparing and retroperitoneal high ligation techniques for varicocele in infertile men. METHODS: We performed a prospective study that included 413 consecutive patients who presented with varicocele. Of the 413 patients, 304 underwent subinguinal varicocelectomy (group 1) and 109 patients underwent high ligation varicocelectomy (group 2). Subinguinal varicocelectomies were performed under local anesthesia, with intravenous propofol sedation administered as needed. The operating microscope (x10 to x16) was used to spare the arteries and lymphatics. High ligation was performed through a retroperitoneal approach. RESULTS: All patients went home on the evening after surgery with minimal discomfort. No intraoperative complications occurred. The internal spermatic artery was identified in all microvaricocelectomy cases. No testicular atrophy occurred in either group. Five (1.6%) and seven (6.4%) hydroceles were identified at the 3-month postoperative visit in groups 1 and 2, respectively. CONCLUSIONS: Microvaricocelectomy is safe and effective and associated with a rapid recovery and minimal morbidity. However, it requires microsurgical training.
