Trends in treatments for erectile dysfunction in Chile between 2010 and 2020 with special focus on penile prostheses.

Objectives: Evidence regarding demand trends for erectile dysfunction (ED) treatments are scarce in South America. This study aims to evaluate trends in ED treatments in Chile over a 10-year period (2010- 2020) and estimate the potential number of candidates for penile prosthesis.

Materials And Methods: Sales trends of pharmacological treatments and penile prosthesis were obtained from market studies.

Successful unilateral vasectomy reversal in a lion ().

Background: In 2016, the veterinarian team of Buin Zoo in Chile decided to try to increase the lion population. At that time, the zoo had three lions; two females and one male. The 9-year-old male had been vasectomized 5 years ago at the same institution for birth control.

[Penile prostheses: Description of a series of implants with and without dilatation of the corpora cavernosa].

Introduction: Penile prosthesis (PP) implantation is the treatment of choice for refractory erectile dysfunction (ED). They show a high satisfaction rate (75%-100%) and a complication rate that varies between 2.1% and 28.

Priapism induced by use of tamsulosin: A case report and review of the literature.

Numerous medications have been associated to the development of priapism as an adverse reaction, the most common are intracavernosal vasoactive agents, antipsychotics and antidepressants. Alpha blockers, in particular tamsulosin which is widely used in different urological conditions, has been associated to priapism in only few case reports. We present the case of a healthy 45-year-old man who medicated himself with two doses of 0.

Clomiphene citrate treatment for late onset hypogonadism: rise and fall.

Objective: Previous series have demonstrated that Clomiphene Citrate (CC) is an effective treatment to increase Total Testosterone (TT) in Late Onset Hypogonadism (LOH) patients. However, what happens to TT levels after ending CC treatment is still debatable. The objective of this study is to evaluate TT levels 3 months after the discontinuation of CC in patients with LOH who were previously successfully treated with the same drug.

Evidence for obtaining a second successive semen sample for intrauterine insemination in selected patients: results from 32 consecutive cases.

Objective: The goal of this study was to compare the semen parameters of two successive samples obtained within an interval of less than 60 minutes from patients planning to undergo intrauterine insemination (IUI) whose first samples exhibited low semen quality.

Methods: Thirty-two consecutive patients were enrolled in the study. On the day of IUI, the semen analysis of the samples initially presented by all patients met at least two of the following criteria: sperm concentration <5×10(6)/mL, total sperm count <10×10(6), progressive sperm motility (a+b) in the native sample <30%, and total motile sperm count (TMSC) <4×10(6).

Microsurgical Spermatic Cord Denervation as a Treatment for Chronic Scrotal Content Pain: A Multicenter Open Label Trial.

Purpose: We prospectively evaluated the results of microsurgical spermatic cord denervation in a series of patients with chronic scrotal content pain in a multicenter study, including 1 center in Germany and 3 centers in Chile.

Materials And Methods: A total of 50 patients with chronic scrotal content pain more than 3 months in duration were prospectively selected for standardized operative microsurgical spermatic cord denervation as pain treatment. In all patients preoperative management included a positive response to a spermatic cord block test with local anesthesia.

Necrosis is the dominant cell death pathway in uropathogenic Escherichia coli elicited epididymo-orchitis and is responsible for damage of rat testis.

Male infertility is a frequent medical condition, compromising approximately one in twenty men, with infections of the reproductive tract constituting a major etiological factor. Bacterial epididymo-orchitis results in acute inflammation most often caused by ascending canalicular infections from the urethra via the continuous male excurrent ductal system. Uropathogenic Escherichia coli (UPEC) represent a relevant pathogen in urogenital tract infections.

Combined trifocal and microsurgical testicular sperm extraction is the best technique for testicular sperm retrieval in "low-chance" nonobstructive azoospermia.

Background: There is no consensus for the best testicular sperm extraction (TESE) technique in patients with "low-chance" nonobstructive azoospermia (NOA).

Objective: To determine sperm retrieval rates in an intraindividual comparison using three locations of the testicle with and without the assistance of a microscope (microsurgical TESE [M-TESE]).

Design, Setting, And Participants: A series of 65 patients with low-chance NOA presenting with low testicular volume (<8 ml) and high serum follicle-stimulating hormone (FSH) (>12.

Tetraethylammonium-sensitive K(+) current in the bovine spermatozoa and its blocking by the venom of the Chilean Latrodectus mactans.

The morphology and size of spermatozoa hinder the study of the functional properties of the spermatozoa plasma membrane. However, some studies have revealed the presence of a number of ion channels in this cell. We set out to measure the endogenous currents and to study the effect of the venom of the Chilean black widow spider (Latrodectus mactans).

Potassium current in mature bovine spermatozoa.

Ion channels have been assigned a pivotal importance in various sperm functions and are therefore promising targets for contraceptive development. The lack of data on channel functionality and pharmacology has hampered this goal. This is a consequence of technical problems of applying electrophysiological techniques to spermatozoa due to their small size and form.

Are antisperm antibodies really associated with proven chronic inflammatory and infectious diseases of the male reproductive tract?

Background: It is debated whether chronic urogenital inflammations and infections may trigger the formation of antisperm antibodies (ASA) in semen.

Objective: To evaluate the formation of ASA in defined chronic inflammatory and infectious diseases of the male reproductive tract (MRT).

Design, Setting, And Participants: Three hundred sixty-five patients retrospectively enrolled in a single center were categorized as having National Institutes of Health (NIH) category II chronic prostatitis (n=38), NIH category IIIa chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) (n=59), NIH category IIIb CP/CPPS (n=213), chronic epididymitis (n=34), and chronic urethritis (n=21).
