Micro-TESE Outcomes for Non-Obstructive Azoospermia — The First Australian Series
Fertility & Reproduction, 2022 Background: Micro-dissection testicular sperm extraction (micro-TESE) for non-obstructive azoospermia (NOA) was shown to achieve the best sperm retrieval rate (SRR) compared to other techniques.

Andrologia, 2021 Limited factors effectively predict sperm retrieval with microdissection testicular sperm extraction in men with nonobstructive azoospermia. We therefore sought to evaluate the role of serum anti‐Müllerian hormone as a predictive biomarker for successful

Practical problems in the posthumous retrieval of sperm [PDF]
Human Reproduction, 2014 This communication discusses the practical problems that arise during the collection and processing of sperm that have been retrieved posthumously. It is based on a small group, namely the last six men from whom we carried out posthumous retrieval. The reason for each retrieval, the method of that retrieval, the assessment of the sperm retrieved, the ...

Advanced Science, EarlyView.High QSOX2 enhances stemness, drug resistance, and metastasis of ESCC cells. QSOX2‐mediated disulfide bond modification activates mTOR/c‐Myc signaling. CAFs‐secreted IGF‐1 drives mTOR/c‐Myc/QSOX2 positive feedback loop. Combining Ebselen, rapamycin, and cisplatin induces tumor dormancy in mice.

Advanced Science, EarlyView.RSPO2 and GDF9:BMP15 heterodimers—core components of oocyte‐secreted factors (OSFs)—coordinate to shape the molecular architecture of preantral granulosa cells via gene‐specific synergistic and antagonistic regulation, mediated through CTNNB1–SMAD2 signaling crosstalk.

Ejaculation failure on the day of oocyte retrieval for IVF: Case report [PDF]
, 2017 Unexpected ejaculation failure on the day of oocyte retrieval for IVF occurs once or twice a year in our Reproductive Medicine Unit, where ∼500 oocyte retrievals are performed each year. Two clinical situations which occurred in 2001 are presented.

Laser microdissection as a new approach to prefertilization genetic diagnosis [PDF]
, 2000 The genetic status of oocytes can be determined by polar body (PB) analysis. Following PB extraction, a genetic evaluation is performed. As each PB contains the complementary genetic material of the oocyte, PB analysis reveals information about its ...

Advanced Science, EarlyView.Abstract Liver cancer stem cells (CSCs) account for tumor initiation, heterogeneity and therapy resistance. However, the role of small nucleolar RNAs (snoRNAs) in the regulation of liver CSCs remains largely unclear. Here, this work identifies a conserved H/ACA box snoRNA SNORA74A which is highly expressed in liver CSCs.
