Successful sperm retrieval from ejaculates of nonmosaic Klinefelter's syndrome (KS) patients by using semen cytology examination was described in this report. The clinical parameters of KS patients with sperm compared to patients without sperm were described. One hundred and fifty-one patients were proven to suffer from KS by chromosomal analysis using G-banding. Spermatozoa were obtained from ...
Accepted for publication June 22, 2012. Study received institutional review board approval. * Correspondence: Androfert, Andrology and Human Reproduction Clinic, Center for Male Reproduction, Av. Dr. Heitor Penteado, 1464, Campinas, São Paulo 13075-460, Brazil (telephone: 55 19 3295-8877; FAX: 55 19 3294-6992; e-mail: [email protected]). Purpose: We evaluated the retrieval rates and re...
BACKGROUND Y chromosome microdeletions are associated with severe male factor infertility. In this study, the success rate of testicular sperm retrieval was determined for men with deletions of AZF regions a, b or c. METHODS AZF deletions were detected by PCR of 30 sequence-tagged sites within Yq emphasizing the AZFa, b and c regions. Semen analysis and diagnostic testis biopsy or testicular ...
Azoospermia in men requires microsurgical reconstruction or a procedure for sperm retrieval with assisted reproduction to allow fertility. While the chance of successful retrieval of sperm in men with obstructive azoospermia approaches >90%, the chances of sperm retrieval in men with non-obstructive azoospermia (NOA) are not as high. Conventional procedures such as fine needle aspiration of the...
Objective: The study aimed to compare intracytoplasmic sperm injection (ICSI) outcome of patients with epididymal sperm and testicular sperm in different paternal age with obstructive azoospermia. Methods: We retrospectively studied the records of 177 men with obstructive azoospermia who underwent sperm retrieval for ICSI. 71 cases were performed with testicular sperm aspiration (TESA), 106 cas...
OBJECTIVES Male infertility caused by irreparable obstructive azoospermia is widely treated with MESA (Microsurgical Epididymal Sperm Aspiration) or TESE (Testicular Sperm Extraction) or PESA (Percutaneous Epididymal Sperm Aspiration) followed by an Intracytoplasmatic Spermatozoa Injection (ICSI). For each procedures are claimed advantages and disadvantages. Aim of this work is to describe our ...
Spinal cord injury (SCI) occurs most often in young men at the peak of their reproductive health. The majority of men with SCI cannot father children naturally. Three major complications contribute to infertility in men with SCI: erectile dysfunction, ejaculatory dysfunction, and abnormal semen quality. Erectile dysfunction can be managed by regimens available to the general population, includi...
INTRODUCTION Congenital bilateral absence of vas deferens (CBAVD) is a non-treatable cause of obstructive azoospermia (OA). However, the affected men can father children by undergoing sperm retrieval (SR) and intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS This video describes percutaneous epididymal sperm aspiration (PESA), performed on a 36 year--old male with CBAVD. In PESA ...
objective: in sever oligospermia; one of the paths used for surgical sperm retrieval (ssr) is to extract sperm via a testicular biopsy. the aim of our study is to determine the reliable time interval between testicular biopsy and intracytoplasmic sperm injection (icsi) procedure in order to obtain optimumsperm parameters (count, motility and normal morphology). materials and methods: this cohor...
