Obstructive and Non-Obstructive Azoospermia
Azoospermia is defined as the complete absence of spermatozoa upon examination of the semen [including capillary tube centrifugation (CTC), strictly confirmed by the absence of spermatozoa issued in urine after ejaculation]. The presence of rare spermatozoa (<500.000/ml) in seminal fluid after centrifugation is called "cryptozoospermia". The complete absence of spermatozoa should be confirmed w...
متن کاملSecretory azoospermia or non-obstructive azoospermia?
In the non-obstructive azoospermia versus the secretory azoospermia it is first necessary to have a clear assessment and definition and then takes care of the patient before the surgical sampling taking into account the age of the woman and in fine try to optimize the residual spermatogenesis. Biopsy seems to be the "gold standard" in non-obstructive azoospermia. The mean level of retrieval (ex...
متن کاملMedical management of non-obstructive azoospermia
Non-obstructive azoospermia is diagnosed in approximately 10% of infertile men. It represents a failure of spermatogenesis within the testis and, from a management standpoint, is due to either a lack of appropriate stimulation by gonadotropins or an intrinsic testicular impairment. The former category of patients has hypogonadotropic hypogonadism and benefits from specific hormonal therapy. The...
متن کاملClinical Comparison of Conventional Testicular Sperm Extraction and Microdissection Techniques for Non-Obstructive Azoospermia
BACKGROUND We compared the efficacy of microdissection testicular sperm extraction (microdissection TESE) and conventional TESE in patients with non-obstructive azoospermia (NOA) and related the positive sperm recovery to certain variables: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, testicular volume and histology. METHODS Sperm retrieval rates (SRR) in patients w...
متن کاملObstructive azoospermia
Obstructive azoospermia (OA) is defined as the absence of spermatozoa in the ejaculate despite normal spermatogenesis, but either a mechanical blockage exists in the genital tract between the epididymis and the ejaculatory duct or the vasa deferentia are absent. A normal testicular biopsy is pathognomonic for obstruction, and a vasography should be indicated to identify the site of the obstruct...
