Surgical Sperm Retrieval Techniques for Assisted Reproductive Technology [PDF]

, 2022
Intracytoplasmic sperm injection provides in vitro fertilization for many infertility conditions. It is also an important treatment option for fertilization in azoospermic men. Sperm production in azoospermic male testicles is possible. In these patients,

Association between anti-Müllerian hormone concentrations and sperm retrieval outcomes in patients with idiopathic nonobstructive azoospermia: a systematic review and meta-analysis

Asian Journal of Andrology
Microdissection testicular sperm extraction (mTESE) is commonly performed to retrieve sperm in the testes for assisted reproductive techniques in patients with idiopathic nonobstructive azoospermia (iNOA).

Sperm retrieval rate and pregnancy rate in infertile couples undergoing in-vitro fertilisation and testicular sperm extraction for non-obstructive azoospermia in Hong Kong [PDF]

Hong Kong Medical Journal, 2016
There are currently no local data on the sperm retrieval and pregnancy rates in in-vitro fertilisation and testicular sperm extraction cycles, especially with regard to the presence of genetic abnormalities. This study aimed to determine the sperm retrieval and pregnancy rates in infertile couples who underwent in-vitro fertilisation and testicular ...

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 ...

Sperm retrieval rates and clinical outcomes for patients with different causes of azoospermia who undergo microdissection testicular sperm extraction-intracytoplasmic sperm injection

Asian Journal of Andrology, 2021
The aim of our study was to compare the sperm retrieval rates (SRRs) and clinical outcomes of patients with different causes of azoospermia who underwent microdissection testicular sperm extraction-intracytoplasmic sperm injection (micro-TESE-ICSI).

Implications of sperm banking for health-related quality of life up to 1 year after cancer diagnosis [PDF]

, 2013
Background: Sperm banking is recommended for all men diagnosed with cancer where treatment is associated with risk of longterm gonadatoxicity, to offer the opportunity of fatherhood and improved quality of life.
