    Varicocelectomy in Patients with Non-obstructive Azoospermia
    (2019) Ozer, Cevahir; Goren, Mehmet Rasit; Gul, Umit; Tunc, Tahsin; Guvel, Sezgin; 0000-0001-6037-7991; AAM-2222-2020
    Objective: We evaluated the outcomes of varicocelectomy in men with non-obstructive azoospermia (NOA) and a palpable varicocele. Materials and Methods: We retrospectively evaluated 25 male patients with NOA having a palpable varicocele, between May 2006 and December 2018. Age, duration of infertility, testicular volume, grade and side of varicocele, varicocelectomy technique, and serum follicle-stimulating hormone, serum luteinizing hormone and serum testosterone levels were analyzed. Results: The mean age of the patients was 30.68 +/- 3.91 years. Of the 25 patients, 5 (20%) had motile sperm in the ejaculate in the postoperative semen analysis. There were no predictive factors affecting the appearance of the sperm in the ejaculate. Conclusion: Varicocelectomy should be considered a treatment option for men with NOA having a palpable varicocele.

    The Effect of Human Chorionic Gonadotropin Treatment Before Testicular Sperm Extraction in Non-Obstructive Azoospermia
    (2016) Gul, Umit; Turunc, Tahsin
    Aim: To investigate our experience on empirical hCG treatment of patients with idiopathic non-obstructive azoospermia (NOAT Material and Method: hCC group consisted of 34 patients who were empirically treated with hCG despite normal serum FSH and LH levels and normal testicular volumes. KG was administered as 2500 IU twice weekly subcutaneous injections for 10 to 14 weeks prior to testicular sperm extraction (TESE). Control group consisted of 49 age and spouse age matched patients who underwent TESE in the same time period. Sperm retrieval rate (SRR), and follicle stimulating hormone (FSH), lutenizing hormone (LH) and testosterone levels, volume of testicles, fertilization rate (FR), implantation rate (IR), pregnancy rate (PR), live birth rate (LBR) and cancel rate (CR) and surgical technique were compared between the two groups. Results: Conventional technique was used in 14 of the 17 patients (82.30/:) with successful sperm retrieval in the KG group, and 18 of the 28 patients (64,390) in the control group (p=0,170). There were no differences between groups in terms of SRR (p=0.338). There were no significant differences in patient age, mean infertility period, mean values of FSH. LH, testosterone, estradiol levels, and testis volume between the two groups (pa0.05). There were no statistically significant differences for FR, IR, PR. LBR between the tuvo groups (p>0.05). Discussion: Empirical hCG treatment in patients with idiopathic NOA did not result in improved SRR. hCG treatment did not have any effect on the success of ICSI.
