Physiological consequences of testicular sperm extraction [PDF]

Human Reproduction, 1997
Testicular sperm extraction (TESE) may provide spermatozoa for attempts at fertility with assisted reproduction; however, the physiological effects of TESE on testicular function are not well understood. In order to evaluate the effects of TESE on the testis, 64 patients were evaluated after TESE for non-obstructive azoospermia with physical ...

Microdissection testicular sperm extraction: an update [PDF]

Asian Journal of Andrology, 2012
Patients with non-obstructive azoospermia (NOA) were once considered to be infertile with few treatment options due to the absence of sperm in the ejaculate. In the last two decades, the advent of intracytoplasmic sperm injection (ICSI), and the application of various testicular sperm retrieval techniques, including fine needle aspiration (FNA ...

The evolution of testicular sperm extraction and preservation techniques [PDF]

Faculty Reviews, 2020
Along with the advent of intracytoplasmic sperm injection in 1992, sperm retrieval procedures now allow the possibility of conception from male sterility. In cases of sterility due to blockages in the reproductive tract, sperm retrieval procedures are relatively straightforward and reliable.

MICROSCOPIC TESTICULAR SPERM EXTRACTION

The Professional Medical Journal, 2018
Azoospermia, the complete absence of sperms in the ejaculate is found in 1% ofnormal males and 10-15% of infertile couples. Surgical sperm retrieval (SSR) and use of spermsfor ICSI/IVF offers an opportunity of parenting to the male factor infertile couples.

Testicular sperm extraction in a patient with metachronous bilateral testicular cancer [PDF]

Human Reproduction, 2001
A new indication for testicular tissue cryopreservation is demonstrated in a patient with metachronous bilateral testicular tumours and azoospermia. At the age of 18 (1982) the patient underwent left orchidectomy and radical retroperitoneal lymphadenectomy for a testicular teratoma (pT1N0M0).

Testicular sperm extraction with intracytoplasmic sperm injection for male infertility [PDF]

Reproductive Medicine and Biology, 2003
Background and Aims: Testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI) is an effective procedure for the treatment of male infertility, obstructive and non‐obstructive azoospermia. We have reviewed our experience to investigate the correlation of TESE‐ICSI with morphological, biophysical and endocrine profiles in 27 men ...

The Use of Immunofluorescence in Microdissection Testicular Sperm Extraction [PDF]

Journal of Andrology, 2009
ABSTRACT: Microdissection testicular sperm extraction (TESE) has been used in the treatment of male infertility in cases of nonobstructive azoospermia (NOA). In some NOA cases, there is significant difficulty identifying sperm within the testes, and we propose that an immunofluorescence technique may assist in locating sperm foci for use in in vitro ...

Testicular sperm aspiration has a poor effect in predicting micro-TESE outcomes in NOA patients with AZFc deletion

Basic and Clinical Andrology, 2023
Background Testicular sperm aspiration (TESA) is widely used in the diagnosis and management of nonobstructive azoospermia. However, its ability for predicting microdissection testicular sperm extraction in nonobstructive azoospermia (NOA) patients with ...

The predictive value of serum sex hormones for the outcome of testicular sperm aspiration in azoospermia [PDF]

Journal of Men's Health
Azoospermia is a condition that affects the reproductive health of approximately 1% of the male population, typically diagnosed through testicular biopsy. Noninvasive serum markers can play a significant role in the diagnosis of azoospermia diagnosis.
