Oogenesis starts in the foetus at around 7 weeks' gestation, when primordial germ cells colonize the newly formed ovary. They are now referred to as oogonia.16. Oogonia undergo mitosis or rapid proliferation (multiplication). WebTransvaginal oocyte retrieval during assisted reproductive technologies (ARTs) was introduced in 1981 [Citation 1 – Citation 3].Owing to its ability to avoid invasive surgery, ultrasound-guided transvaginal oocyte retrieval has replaced laparoscopic retrieval and has become the gold standard for human in vitro fertilization (IVF) [Citation 1 – Citation 3].
