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...

Secretory 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...

Expression analysis of MND1/GAJ, SPATA22, GAPDHS and ACR genes in testicular biopsies from non-obstructive azoospermia (NOA) patients

BACKGROUND High-throughput studies provide a wide spectrum of genes for use as predictive markers during testicular sperm extraction (TESE) in combination with ICSI. In this work, we used the specimens from testicular biopsies of men with non-obstructive azoospermia who underwent TESE to investigate the expression of spermatogenesis-related genes MND1, SPATA22, GAPDHS and ACR. METHODS Testicu...

The measurement technologies of thyrotropin receptor antibodies from the past to the present

Thyroid Stimulating Hormone Receptor (TSH-R) autoantibodies are the main cause of Graveschr('39') disease and its external thyroid manifestations such as ophtalmopathy and dermatopathy. These antibodies are functionally different and are commonly called TSH receptor antibodies (TRAbs). In fact, TRAbs are a set of autoantibodies including TSHR-stimulating antibodies (TSAbs), TSHR- blocking antib...
