    We aimed to investigate the relationship between premature ejaculation and the age when men had been circumcised before adulthood. A total of 2,768 sexually active male patients aged between 18 and 65 years were included in this study. A multicentre study was conducted prospectively with the participation of 20 centres. A survey consisting of 12 questions prepared by the researchers, as well as the validated Turkish versions of the five-item Premature Ejaculation Diagnostic Tool, was administered to all participants. The study included 1,603 participants who met the inclusion criteria. There was no significant difference in the Premature Ejaculation Diagnostic Tool and self-reported ejaculation time between the participants who had been circumcised at different ages during childhood. Remembering circumcision experience with fear or anxiety did not increase the risk of sexual dysfunction compared to the participants who described their experience with happiness or with no particular emotion. There was no significant difference in Premature Ejaculation Diagnostic Tool scores or the self-reported ejaculation time of the participants circumcised at different ages. The age of childhood circumcision, having a fearful or anxious circumcision experience, does not affect the risk of premature ejaculation in adult life.

    Parameters predicting sperm retrieval rates during microscopic testicular sperm extraction in nonobstructive azoospermia
    (2019) Kizilkan, Yalcin; Toksoz, Serdar; Turunc, Tahsin; Ozkardes, Hakan; 0000-0002-7277-449X; 31583760; AAH-1052-2020
    The aim of this study was to investigate the predictive value of the parameters that might have an effect on the success of microscopic testicular sperm extraction (micro-TESE) in infertile patients with nonobstructive azoospermia (NOA). Between 2003 and 2014, 860 patients with NOA were retrospectively analysed. The effect of age, infertility duration, history of varicocelectomy, herniorrhaphy or orchiopexy, presence of solitary testis, tobacco use, previous testicular biopsy results, history of orchitis, usage of human chorionic gonadotropin in the past three months, presence of undescended or retractile testis, presence of varicocele, testicular volume, levels of serum follicle-stimulating hormone, luteinising hormone, and testosterone, presence of Klinefelter syndrome and micro-deletion of Y chromosome on sperm retrieval rates were evaluated. In 45.8% (n = 394) of the patients who underwent micro-TESE, spermatozoon was adequately obtained. Multiple logistic regression analysis demonstrated that previous successful testicular biopsy (OR = 15.346; GA = 5.45-43.16; p < .001) and higher testicular volumes significantly increase sperm retrieval rate in micro-TESE. The testicular volume cut-off as 11 ml was found to be the most significant factor. Although currently testicular biopsy result is not being used as a diagnostic method, it is significantly associated with micro-TESE result.
