Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* The relevance of male infertility has progressively grown , with significant medical, psychological, and socio-economic implications. .. With no sperm found at multiple semen analyses, non-obstructive azoospermia (NOA) is the most severe form of infertility.
* The introduction to clinical practice of assisted reproduction techniques such as intra-cytoplasmic sperm injection (ICSI) made fatherhood possible for men with (NOA). The extraction of sperm from the testis through testicular sperm aspiration (TESA), testicular sperm extraction (TESE) or open biopsy can result in a favorable reproductive outcome. Nevertheless, all these procedures are invasive in nature with variable possibility of successful sperm extraction. As a consequence, a non-invasive test that could predict the presence of sperm in men with NOA would be of profound clinical importance
* However, the lack of useful predictive biomarkers suggestive for successful sperm retrieval at microTESE and TESA in NOA men still represents a relevant gap with a very negative return for the patient. Indeed, no significant association has been found between microTESEand TESA sperm retrieval outcomes and preoperative testicular volume, baseline follicular stimulating hormone (FSH) levels, basal level of Testosterone (T) or increased T level following treatments with aromatase inhibitors, clomiphene citrate or human chorionic gonadotropin.
* Therefore, it has been amust to identify novel and user-friendly prognostic factors reliably predicting surgical outcomes in NOA men in the real-life setting. Among other variables, some hormons can be subjected to studies for this purpose such as levels of testis-derived hormones (which might be representative of the primary testicular failure) as the Anti-Müllerian Hormone (AMH),( which is suggestive for a Sertoli cells' immature phenotype),and testosterone of biological relevance...
* An investigation from the early 1970s demonstrated that the human testis does indeed secrete estradiol within the spermatic vein, at amean concentration that is 50 times greater than that inthe peripheral plasma . These findings led to the hypothesis that local estrogen levels might be associated with the current stateof spermatogenesis, or the total number of spermatogenic cells in the testis.
