Topic 2 Human Reproductive Anatomy: In Vitro (IVF) vs In Vivo Conception

Question 1

• Looks at cells and biological molecules outside their normal biological context, such as in a lab.
• IVF (in vitro fertilization) with microinjection is more effective than regular IVF. IVF with microinjection involves delivering sperm directly to the egg via a needle, whereas in regular IVF the sperm and egg are mixed together in a dish for ‘natural’ fertilization
  a. Microinjection success rate is ~75% and helps with male fertility because low sperm count or abnormally swimming sperm are no longer a problem

Answer 1

In Vitro

Question 2

• Normal biological environment

- Natural conception (in vivo) normally has a higher success rate than IVF

Answer 2

In Vivo
