Introduction: Microdissection testicular sperm extraction (microTESE) is considered the gold standard method for surgical sperm retrieval among patients with non-obstructive azoospermia (NOA). Aim: This study aimed to evaluate the correlation between histopathological findings after failed microTESE procedure and outcomes of the „second-look“ procedure and to provide insight into the most common histopathological patterns after testicular biopsy within our population. Methods: The retrospective study included 33 selected patients with NOA, who had undergone unsuccessful sperm retrieval. The diagnosis of NOA was made after the assessment of the patient’s history data, a physical examination, semen analysis, the hormonal profile, and genetic studies. After negative sperm retrieval, histopathological report has been analyzed for „second-look“ microTESE attempt. Results: Five testicular histopathological patterns were found: hypospermatogenesis (9,1%), Sertoli cell-only syndrome (43%), germ cell maturation arrest (15%), seminiferous tubule hyalinization (15%), mixed pattern (21%). Y-microdeletions were detected in 5 patients, of which 3 patients showed AZFc region deletions. Only 3 patients (9,1%) underwent a „second-look“ procedure after the evaluation of histopathological reports. After the stimulation therapy and „second-look“ procedure, we had a positive outcome in a single patient (33,3%). Mean FSH value in patients with confirmed spermatogenesis was 17.26±3.11IU/l, while mean FSH value in patients without presence or germ cell statistically significantly exceeded and was 24.28±4.71IU/L (p=0.038). Conclusion: Histopathological reports following the microTESE procedure are obligatory for the proper selection of patients who are candidates for the „second-look“ microTESE attempt. Patients with Sertoli cell-only syndrome and hypospermatogenesis particularly can benefit from the “second-look” procedure.

Background/aim To evaluate the effects of hysterectomy on rat ovaries and the possible protective role of peroxisome proliferator-activated receptor gamma (PPAR-γ) agonist-rosiglitazone against ovarian reserve decrement. Materials and methods Forty-five adult Wistar albino rats were randomly divided into three groups. Hysterectomy was performed (n = 15) in group 1 [H]; 1 mg/kg/day PPAR-γ agonist/rosiglitazone was used for 50 days after hysterectomy (n = 15) in group 2 [H + R]; a sham operation was performed (n = 15) in group 3 [control, C]. Blood samples were collected for anti-Müllerian hormone (AMH) evaluation in all groups and simultaneous ovarian Doppler examination was performed in [H] and [H + R] groups before and after (50 days) hysterectomy. All animals were sacrificed to obtain ovaries for histological examination. Results AMH levels were found to be significantly decreased at postoperative day 50 in all groups (P < 0.05). Histopathologic analysis showed that primary, preantral, and antral follicle counts were significantly higher in the [H] group as compared to the [C] and [H + R] groups (P < 0.05). There was no significant difference between the [C] and [H + R] groups in terms of follicle numbers (P > 0.05). In the ovarian Doppler blood flow analysis, all parameters were significantly decreased in group [H] (P < 0.05), but not in the [H + R] group (P > 0.05) on postoperative day 50. Conclusion Hysterectomy affects the histopathological structure of rat ovaries and PPAR-γ agonist-rosiglitazone improves the ovarian Doppler blood flow parameters.

Introduction: Main categorisation of azospermic is in two grups: nonobstructive azoospermia (NOA) and obstructive azoospermia (OA). We had evaluation of prognostic factors and determinants in sperm retrieval procedures in azoospermic patients. Methods: Retrospective evaluation observed 21 selected patients with NOA and OA azoospermia, after that complete history, physical examination with ultarsound volume of testis and hormonal profile. Hormonal profile included: follicle stimulating hormone (FSH), luteinizing hormone (LH), testosteron (T) and prolactin (P) serum levels. Also karyotype and Y-deletion analysis were done and analyzed. Results: 9 OA patients (42,9%) were undergone for TESE operation and 12 NOA patients (57,1%) for Micro-TESE operation. All TESE procedures were positive (100%). Micro-TESE in 12 selected NOA patients, 5 patients (41,6%) were positive and 7 patients (58,4%) negative. Patients testicular size, serum FSH and testosterone level showed correlation in success of sperm retrieval procedures. Conclusion: TESE is elected procedure for obstructive azospermia (OA). Micro-TESE is appropriate sperm retrieval procedurec for patients with non-obstructive azoospermia (NOA) and correlate with high FSH and small volume of testis.

Objective: Assisted reproduction techniques have become widespread worldwide. Considering their costs, physicians endeavor to improve pregnancy rates. Infections are one of the disrupting problems in this arena. We aimed to investigate the effects of screening for vaginal infection on pregnancy rates in intracytoplasmic sperm injection cycles. Materials and Methods: One hundred twenty patients randomized into two groups for this study. Patients were screened for vaginal infections in group 1, and no screening was performed in group 2. The assisted reproduction outcomes were investigated and compared between the two groups. Results: There was no significant difference between ages, or durations and causes of infertility of patients who conceived and of those who did conceive. Forty-five patients in group 1, and 40 patients in group 2 reached the embryo transfer stage. The rates of conception were 23.5% (n=4) in culture-positive patients (n=17), and 42.9% (n=12) in culture-negative patients (n=28) in group 1. There was no significant difference among patients who were not screened, screen-positive, and screen-negative, in terms of pregnancy rates. None of the patients had Neisseria gonorrhoeae or Trichomonas vaginalis. Bacterial vaginosis was detected in 13 patients, and both bacterial vaginosis and Chlamydia trachomatis were detected in 4 patients. Three of 4 patients who conceived screen-positive and 8 of 12 patients who conceived screen-negative delivered healthily at term. Conclusion: No significant difference was found between patients who were sampled for culture and patients who were not sampled in terms of pregnancy rates. Also, no difference was found between the patients who were culture-negative and patients who were treated with antimicrobials after a culture positive result. Further larger studies are warranted to clarify this issue.

Introduction: To present results of MicroTese procedure in treatment of male infertility in patients with azoospermia at Bahçeci BIH IVF Center during two-year period of 2013-2014. Methods: In the stated time-period, 55 MicroTese surgeries were performed. In 52.7% of the cases, sperm cells were isolated after MicroTese surgery, and in 47.3% of the cases, there was a negative outcome of the procedure. Obtained sperm cells were subjected to cryopreservation. Furthermore, ICSI procedure was performed by use of the obtained sperm cells. Results: Of 29 positive MicroTese surgeries, 21 (72.4%) resulted in clinical pregnancies. Biggest percentage of negative MicroTese procedures happened in patients with cryptorchidism and orchidopexy. Conclusion: MicroTese is the most precise and successful method of retrieving sperm cells surgically in men with azoospermia. Our results are within scope of results in referent world centers.
