Human Fertilization and IVF

ANAT2341 Lab 1: Introduction | Gametogenesis | Oogenesis | Spermatogenesis | Fertilization | Sex Determination | Online Assessment | ANAT2341 Lab 1 - Quiz

Sir Robert Geoffrey Edwards, the ‘father of assisted reproduction technology’ (ART) was knighted in the 2011 Queen’s Birthday Honours for services to human reproductive biology. He has the great distinction of being the only Nobel Laureate in the field of ART, having been awarded the 2010 Nobel Prize for the development of in vitro fertilisation (IVF). Sadly, he died in 2013 but he will be remembered as an inspirational visionary in many fields of research. His landmark articles published in the 1960s in ‘Nature’ on the in vitro maturation of oocytes partly unveiled the origins of aneuploidy through non-disjunction of chromosomes. In addition, in collaboration with Robin Cole, he managed to generate embryonic stem cells from blastocysts. These remain areas of intense research some 50 years later! The research group that Bob built at Cambridge University provided evidence, through the sexing of rabbit embryos, that pre-implantation genetic diagnosis was feasible some 20 years prior to its clinical application. They also demonstrated IVF in the human 10 years prior to the birth of the world’s first IVF baby in 1978, the momentous culmination of Bob’s serendipitous collaboration with Patrick Steptoe.

Introduction

Historic drawing of oocyte and spermatozoa relative sizes

This first lab will be taken by Dr Steven Fleming

Dr Fleming is the Scientific Director of Assisted Conception Australia - Honorary Associate, University of Sydney - And the former Scientific Director of the In Vitro Fertilization Clinic in Westmead Hospital, Sydney Sperm binding to zona.jpg

Objectives

  1. This tutorial/laboratory will focus on human gametogenesis and fertilization.
  2. Discuss issues relating to human assisted conception and learn modern cutting-edge techniques in this field
  3. Have an opportunity to ask questions concerning practicalities, problems, ethical concerns and any other issues related to human fertilization
  4. The learning objectives are as follows:

Gametogenesis and the origins of aneuploidy; Oocyte maturation, sperm capacitation and fertilisation; Assisted fertilisation techniques and their eithical implications
