ABSTRACT
A potential role of oxidative stress has been implicated in the outcome of various steps of assisted reproductive technology (ART). In a prospective cohort study, a total of 100 patients undergoing IVF/ICSI procedure due to male factor infertility were recruited based on the inclusion criteria. In all patients, 1-2ml of endometrial secretions was aspirated prior to embryo transfer. The oxidative stress markers in endometrial secretions, including superoxide dismutase (SOD), catalase (CAT) activities, lipid peroxidation (LPO), total thiol groups (TTG), and total antioxidant power (TAP) were investigated and compared among study groups including term pregnancy, failed IVF cycle, and miscarriage. P<0.05 was considered statistically different. Of the 100 patients, 28 cases (28%) resulted in ongoing pregnancy (biochemical pregnancy followed by clinical pregnancy), 11 cases (11%) resulted in miscarriage, and 61 cases (61%), resulted in failed IVF cycle. SOD, LPO, CAT, and TAP levels in the endometrial secretions of the three groups were statistically different (P-value <0.01, <0.001, <0.001, and <0.001, respectively). TTG levels in endometrial secretion of three groups were not statistically different (P-value=0.837). Our results indicated that higher levels of antioxidants such as SOD, CAT, or TAP, and lower levels of oxidative stress markers such as LPO in the endometrial secretions were associated with successful IVF outcome.

INTRODUCTION: Leiomyosarcoma is a malignant soft tissue tumor that can arise from any tissue containing smooth muscle. Leiomyosarcomas of the spermatic cord are rare tumors of non-testicular origin, which drain into the retroperitoneal lymph nodes and have been reported in less than 150 cases in the literature until now. Radical inguinal orchiectomy and high ligation of the cord is the standard primary surgical procedure in spermatic cord leiomyosarcoma. CASE PRESENTATION: Here we reported a 75-year-old man who presented with a painless lump in the right hemiscrotum. A right radical orchiectomy was performed. Histopathology confirmed a neoplastic tissue with mesenchymal origin in spermatic cord; further evaluation revealed a leiomyosarcoma of the spermatic cord. The patient was followed up for 1-year and shows no signs of recurrence. CONCLUSIONS: Preoperative diagnosis of spermatic cord leiomyosarcma is difficult and commonly made by histological examination and immunochemical staining.
