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 ...

Endocrine Tests and/or Testicular Volume are Not Predictive of Successful Sperm Retrieval by Conventional Multiple Testicular Sperm Extraction in Nonobstructive Azoospermia

Fertility & Reproduction, 2020
Objectives: This study aimed to determine the role of presurgical markers in the prediction of sperm retrieval by conventional Multiple Testicular Sperm Extraction in infertile Vietnamese men with nonobstructive azoospermia (NOA).

Is testicular microdissection the only way to retrieve sperm for non-obstructive azoospermic men?

Frontiers in Reproductive Health, 2022
Men presenting with non-obstructive azoospermia are the most challenging clinical scenario for an infertile couple. Intracytoplasmic Sperm Injection (ICSI) with testicular sperm retrieval gave a chance for biological fatherhood once sperm can be found ...

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 ...

Testicular expression of TDRD1, TDRD5, TDRD9 and TDRD12 in azoospermia. [PDF]

, 2020
BACKGROUND: Tudor domain-containing proteins (TDRDs) play a critical role in piRNA biogenesis and germ cell development. piRNAs, small regulatory RNAs, act by silencing of transposons during germline development and it has recently been shown in animal ...

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.

A novel stepwise micro-TESE approach in non obstructive azoospermia [PDF]

, 2016
Background: The purpose of the study was to investigate whether micro-TESE can improve sperm retrieval rate (SRR) compared to conventional single TESE biopsy on the same testicle or to contralateral multiple TESE, by employing a novel stepwise micro ...

Exposure to polychlorinated biphenyls and hexachlorobenzene, semen quality and testicular cancer risk [PDF]

, 2015
PURPOSE: We carried out a case-control study to investigate the possible role of occupational and environmental exposure to endocrine disruptors in the onset of testicular cancer (TC). METHODS: We evaluated 125 TC patients and 103 controls.

Onco-testicular sperm extraction (onco-TESE) for bilateral testicular tumors: two case reports

Journal of Medical Case Reports, 2017
Background Most patients with testicular cancer are infertile; thus, the preservation of the sperm after surgery is an important factor to consider. We report two cases of bilateral testicular cancer in patients who underwent bilateral higher orchiectomy
