Autor: Raymond Hang Wun Li, Su-Bin Liao, William Shu Biu Yeung, Ernest Hung Yu Ng, Wai Sum O, Pak Chung Ho

Publikováno v: Reproductive Biology and Endocrinology, Vol 22, Iss 1, Pp 1-5 (2024)

Abstract Background Levonorgestrel (LNG) acts as an emergency contraceptive mainly by inhibiting or postponing ovulation. We carried out this study to investigate whether LNG at concentration relevant for emergency contraception (EC) affect ciliary b

Randomised double-blind controlled trial of non-invasive preimplantation genetic testing for aneuploidy in in vitro fertilisation: a protocol paper

Autor: William Shu Biu Yeung, Ernest H Y Ng, Hiu Yee Heidi Cheng, Judy F C Chow, Kevin K W Lam, Shui Fan Lai

Publikováno v: BMJ Open, Vol 13, Iss 7 (2023)

Introduction The success rate of in vitro fertilisation (IVF) treatment for couples with infertility remains low due to lack of a reliable tool in selecting euploid embryos for transfer. This study aims to compare the efficacy in embryo selection bas

Current progress on in vitro differentiation of ovarian follicles from pluripotent stem cells

Autor: Genie Min Ju Wu, Andy Chun Hang Chen, William Shu Biu Yeung, Yin Lau Lee

Publikováno v: Frontiers in Cell and Developmental Biology, Vol 11 (2023)

Mammalian female reproduction requires a functional ovary. Competence of the ovary is determined by the quality of its basic unit–ovarian follicles. A normal follicle consists of an oocyte enclosed within ovarian follicular cells. In humans and mic

Publikováno v: Advanced Science, Vol 10, Iss 11, Pp n/a-n/a (2023)

Abstract Human expanded potential stem cells (hEPSC) have been derived from human embryonic stem cells and induced pluripotent stem cells. Here direct derivation of hEPSC from human pre‐implantation embryos is reported. Like the reported hEPSC, the
