In non-obstructive azoospermia spermatozoa can usually only be isolated from the testicles, and thus the most promising treatment model is testicular sperm extraction (TESE). Hormone concentrations, testicular volume determinations and testicular biopsy results are not uniform enough to select potential candidates for successful TESE and intracytoplasmic(More)
Thirty-two infertile couples with obstructive and non-obstructive azoospermia were included in this study. Testicular sperm extraction (TESE) was performed in 16 obstructive azoospermic cases where microsurgical sperm aspiration (MESA) or percutaneous sperm aspiration (PESA) were impossible because of totally destroyed epididymis and 16 non-obstructive(More)
The efficacy of intracytoplasmic sperm injection (ICSI) employing testicular and ejaculated spermatozoa was assessed in 24 couples with totally or initially immotile spermatozoa. No criteria were employed in selecting which patients would be treated with testicular or ejaculated spermatozoa. The men were chosen at random. Testicular spermatozoa obtained by(More)
The present study was designed to determine the efficacy of intracytoplasmic sperm injection (ICSI) using spermatozoa with abnormal head morphology in 17 cases with total teratozoospermia. A total of 160 oocytes were retrieved and 144 metaphase II oocytes were injected. The fertilization and cleavage rates were 50.7 and 93.2% respectively. Fertilization(More)
Systemic lupus erythematosus and Sjögren's syndrome are chronic auto- inflammatory disorders which can lead to serious organ damage. Although systemic lupus erythematosus and Sjögren's syndrome were previously considered two forms of the same disease because of presence of clinical coexistence of these two conditions, the view that they are two different(More)
Since the advent of assisted reproductive technology, the concern about ectopic implantation of embryos has increased dramatically. Simultaneous bilateral tubal pregnancy is the least common type of ectopic implantation of two embryos. In this report we present the first case of simultaneous bilateral tubal pregnancy after intracytoplasmic sperm injection(More)
This study included 124 men from infertile couples who were referred to the Department of Obstetrics/Gynecology, Akita University Hospital, Japan. All the patients had a history of involuntary infertility lasting for at least 2 years. Serum antichlamydial antibodies were measured by indirect immunofluorescence technique. The antigen used for testing was(More)
The aim of this study was to evaluate the presence of subclinical cardiovascular disease (CVD) and its relation to risk factors in pediatric patients with steroid-resistant nephrotic syndrome (NS). Thirty-seven patients with normal renal function were compared with 22 healthy controls regarding the presence of subclinical CVD. Measurements included aortic(More)
Esophageal submucosal hematoma is a rarely observed condition in which abrupt bleeding occurs between the mucosa and muscularis propria of the esophageal wall, often involving a long portion of the esophagus. Possible causes of submucosal hematoma of the esophagus include external trauma, endoscopic sclerotherapy of the esophageal varices, vigorous(More)
The aim of this study was to determine whether the endometrium acts as a reservoir for Candida albicans in cases of recurrent vaginal candidiasis. Twenty-five women with documented history of recurrent vaginal candidiasis were enrolled in the study and endometrial samples were cultured for Candida albicans. Only two patients had positive cultures for(More)
