Gonadectomy is widely used to treat and prevent behavior problems including the aggressive behavior of dogs. The aim of this study was to determine whether aggressive behavior toward familiar people, strangers, or other dogs was significantly different in dogs gonadectomized at various ages vs. intact dogs using the Canine Behavioral Assessment Research Questionnaire (C-BARQ) with multivariate analysis. Of 15,370 initial surveys, those for dogs reported to have been gonadectomized at less than 6 weeks of age or to correct a behavior problem, and those with incomplete answers to questions regarding independent or dependent variables were excluded, leaving 13,795 for the analysis of aggressive behavior toward familiar people: 13,498 for aggressive behavior toward strangers and 13,237 for aggressive behavior toward dogs...

PURPOSE: Evidence on the effect of vasectomy on prostate cancer is conflicting, with the issue of detection bias a key criticism. We examine the effect of vasectomy reversal on prostate cancer risk in a cohort of vasectomised men; evidence of a protective effect would be consistent with a harmful effect of vasectomy on prostate cancer risk, while nullifying the issue of detection bias. METHODS: Data were sourced from five population-level linked health databases located in Australia, Canada and the United Kingdom...

BACKGROUND: Ejaculation consists of the emission of semen from seminal vesicles and prostate, followed by expulsion. Ejaculatory dysfunction may take several forms including premature ejaculation, delayed or anejaculation, retrograde ejaculation, and painful ejaculation. Ejaculation is what we can see whereas orgasm is what we feel. The presence of ejaculate does not indicate the ability to experience orgasm. Hence, for the purpose of this work we consider orgasm and ejaculation as 2 separate neurobiological phenomena...

This study aims to evaluate whether cancer treatments differ in infertile men compared to men who have undergone vasectomy and age-matched controls. We analyzed subjects from the Truven Health MarketScan Claims database from 2001 to 2009. Infertile men were identified through diagnosis and treatment codes. Comparison groups included vasectomized men and an age-matched cohort who were not infertile and had not undergone vasectomy. We considered cancer types previously associated with infertility that were diagnosed after the diagnosis of infertility...

In developed countries, women bear the primary, and sometimes exclusive, responsibility for preventing pregnancy in heterosexual sexual relations. This unequal burden is not an intrinsic fact; it is the consequence of broad social narratives and interpersonal negotiations. The contraceptive counseling visit is increasingly recognized as a site of the discursive production of normative ideas about reproduction, suggesting that clinicians themselves may contribute to the assignment of responsibility for contraceptive labor to women (i...

INTRODUCTION: Post Vasectomy Pain Syndrome (PVPS) is an uncommon urologic problem that remains a challenge to manage. We aim to evaluate the outcomes of patients who underwent microdenervation of the spermatic cord (MDSC) for PVPS at our institution. METHODS: A retrospective study of all patients who underwent MDSC for PVPS by a single surgeon from March 2002 to October 2016 was performed. Pain was documented using the numerical rating scale (NRS). Spermatic cord block (SCB) was performed on all patients and success was defined as NRS ≤1 for >4 hours...

Population control techniques, either permanent or reversible, are important tools for the management of wildlife in captive and natural environments. Among these, surgical sterilization provides a permanent solution to unwanted reproduction. Surgical techniques can differ in their invasiveness and in the subsequent effect on behavior and physiology. For social animals, techniques that preserve gonads, such as vasectomy for males and ligation of uterine tubes for females, may be preferred because they maintain important physiology that influences behavior...

The laboratory mouse is the most used animal model in biomedical research. Several artificial reproductive techniques, such as revitalization of cryopreserved strains, rederivation after hygienic contaminations and the production of transgenic mouse models, require the transfer of preimplantation embryos to surrogate mothers. Pseudopregnancy is essential in recipient females and is induced by mating with sterile males. Commonly, surgically vasectomized males are used for this purpose. As an alternative, genetically modified mouse strains have been identified, in which homozygous infertile males are sexually active...

Vasitis nodosa is a benign proliferation of vas deferens epithelium, thought to be a response to trauma or obstruction, usually vasectomy. Although histologic features mimic malignancy, diagnosis is usually straightforward due to the clinical context. We analyzed 21 specimens with vasitis or epididymitis nodosa with antibodies to PAX8, CD10, p63, alpha-methyl-acyl-coA-racemase (AMACR), GATA3, prostein, NKX3.1, and prostate-specific antigen (PSA). Two diagnostically problematic cases included 1) florid bladder muscle involvement after prostatectomy and 2) involvement of the ampulla and ejaculatory duct in a radical prostatectomy specimen...

Female sterilization procedures include postpartum partial salpingectomy via cesarean or minilaparotomy incision, interval laparoscopic procedures, or hysteroscopic placement of microinserts. Rates of failure and serious complications are low and comparable among the various methods. A hysteroscopic procedure requires a 3-month confirmatory hysterosalpingogram before it is considered effective for contraception. Hysteroscopic sterilization has been shown to be associated with a higher reoperation rate than laparoscopic procedures...

BACKGROUND: The golden-headed lion tamarin (Leontopithecus chrysomelas), originally endemic to Bahia, was introduced in Rio de Janeiro. The species is currently found in remaining forests within the region of original occupation of the golden lion tamarin (Leontopithecus rosalia), which may compromise the survival of the golden lion tamarin. Groups of golden-headed lion tamarins were captured and translocated to Bahia. However, the area chosen reached its limit and males underwent to vasectomy procedures...

BACKGROUND: Gender roles influence men's attitudes towards reproductive health, and society might assume that reproductive health issues, fertility and family planning are women's responsibilities. Moreover, literature shows that men have insufficient knowledge about reproductive health matters and some misconceptions about modern contraceptive practices. OBJECTIVES: The aim of the study was to describe reproductive health knowledge of men in Mankweng District and was conducted in 2015...

Introduction: Vasectomy is the simplest, safest, and most effective form of definitive fertility control in men [1]. Vasectomy is used for 10% of contraception worldwide but only for 2% in Germany [2]. The aim of this study was to investigate the impact of vasectomy on the sexual satisfaction of sterilized men and their partners. Material and methods: Vasectomized men and their partners were surveyed by means of the IIEF (International Index for Erectile Function) and the FSFI (Female Sexual Function Index) questionnaires...
