Secretory azoospermia or non-obstructive azoospermia?
نویسنده
چکیده
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 (extracted) spermatozoa is of 50%, with 20% of pregnancy/cycle and 30% of delivery/coupe with a better success for frozen sperm samples.

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 کاملFertilization, pregnancy and embryo implantation rates after ICSI in cases of obstructive and non-obstructive azoospermia.
The aetiology of azoospermia can be grossly divided into obstructive and non-obstructive causes. Although in both cases testicular spermatozoa can be used to treat male fertility, it is not well established whether success rates following intracytoplasmic sperm injection (ICSI) are comparable. Therefore, a retrospective analysis of fertilization, pregnancy and embryo implantation rates was perf...

Background The genetic association between cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations and male infertility due to congenital bilateral absence of vas deferens (CBAVD) is well established. Mutant CFTR, however may also be involved in the etiology of male infertility in non-CBAVD cases. The present study was conducted to estimate the frequency of ΔI507 and ΔF508 CFT...
