The PB seems to have a moderated impact on the sexual functions and the sexual behavior of the patients.

Background: Men with congenital unilateral absence of vas deferens were reported to be mainly azoospermic, with both unilateral renal absence and mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) but some have neither. Objectives:To assess whether in infertile couples the male partners with congenital unilateral absence of vas deferens are mainly azoospermic men. Material and Methods: Retrospective study in a unique university hospital; reproductive, clinical, CFTR analysis and seminal data of male partners of infertile couples (from 1998 to 2018) were analysed. Diagnosis of congenital unilateral absence of vas deferens was based on transrectal ultrasounds (TRUS): complete or partial absence of one vas deferens with complete contralateral vas deferens confirmed in 63 men. Distribution of sperm count in three classes: azoospermia, oligozoospermia or normozoospermia. Ultrasound determination of renal status; seminal biomarkers assays; and search for CFTR mutations.Results: Among the 63 men, 39.7% displayed azoospermia, 27% oligozoospermia and 33.3% normozoospermia; 42% of the non-azoospermic men (16/38) had previously obtained a natural pregnancy. We found unilateral renal absence in 17/59 patients (29%). Among 50 men with CFTR testing, five carried an allele associated with cystic fibrosis belonging to the 29 men without renal anomalies, indicating a high allelic frequency (8.6%). The 63 patients displayed high rates of surgical histories for undescended testicles or inguinal hernia, low values of semen volume and of total seminal glycerophosphocholine. Conclusions:Our results indicate that men with congenital unilateral absence of vas deferens mainly display oligozoospermia or normozoospermia and that they were previously fertile. They clearly confirm, first, that CFTR testing is recommended in congenital unilateral absence of vas deferens men and it should be mandatory for those with normal kidneys; and, second, that TRUS is needed for the diagnosis of congenital unilateral absence of vas deferens. As congenital unilateral absence of vas deferens may be present whatever the sperm count, biological warnings are represented by semen volume and seminal epididymal markers and clinical warnings by surgical histories of undescended testes or inguinal hernia.

To determine the risk factors for EDin men treated by prostate brachytherapy (PB) for localized prostate cancer and to propose a model to predict post-implant erectile function. Out of a series of 270 sexually active men treated by PB, 241 (89%) (mean age=66 years (range, 43-80)) accepted to participate in a mail-based study on erectile function. The risk factors for erectile dysfunction were determined by regression analysis and a predictive model was proposed. The performance of the model was determined in this population and subsequently verified in a population of 50 men treated by PB in another treatment center. The risk factors for ED after PB were age, the pre-implant IIEF score and prostate volume. In the studied population, the final model to predict a post-treatment IIEF-5 score, using these factors, had a sensitivity of 69% and a specificity of 68% associated to an area under the ROC curve (AUC) of 0.75. The same performance was obtained in another treatment center. Age, pre-implant IIEF-5 score and prostate volume may be used to predict post-implant erectile function in patients treated by PB.

PurposeTo assess sexual functions and behaviors of men treated by penile brachytherapy for a cancer of the penis.Materials and methodsThirty eight men (19 patients treated by penile brachytherapy for a cancer of the penis and 19 age paired-matched controls) participated in a survey about sexuality. The mean age of patients and controls were 73.2 +/- 11.7 and 70.0 +/- 10.5 years, respectively (NS). Controls were men without penile pathology, without history of cancer and no evidence of cognitive impairment. All agreed to participate in the survey about sexuality using 2 questionnaires : the IIEF questionnaire, which explores 4 domains of sexual functions, namely erection, satisfaction, orgasm and desire, and a questionnaire created using the BASIC IDEA grid, which addresses nine domains: behavior, affect, sensation, self-image, cognition, interpersonal, drugs, expectation and attitude.ResultsPatients had better scores than controls in 3 domains of the IIEF: erection, desire and satisfaction. These results contrasted with the frequency of intercourse and the quality of erection (evaluated through the BASIC IDEA questionnaire) that were not significantly different between the two populations. Patients also had significantly higher frequency of masturbation (p <0.001) lower worry about sexual performance and higher expected satisfaction for future life (p: 0.021) than controls.ConclusionPenile brachytherapy is a treatment of cancer of the penis that seems to have a moderated impact on sexual functions since most of sexual scores are not inferior in these patients than in age pair-matched controls.
