The Baby Factory
Where babies come from
theory of preformation
ovist
spermist
19th century
Oskar Hertwig
1 egg + 1 sperm = new offspring
Infertility
15% world population -> infertile
solutions
artificial insemination - >only invention in 1921
1978 -> test tube baby -> in vitro fertilization (IVF)
technologies -> ART
The menstrual cycle
ART = injection of hormones = fertilizable eggs
Intercourse
IVF
Ability to store eggs
Research --> eggs produced in ovaries
Vitro maturation
Faster than hormone - proces
Early days of life
ICSI
intracytoplasmic sperm injection
used for Claudy
preimplantation genetic diagnosis
snip-and-see procedure
looking -> disease-linked gene
researching development embryos
Sperm meets egg
ART
First Laboratory Fertilization (1934)
experimenting in labs
Louise Brown 1978
first test tube baby
sperm
simple to understand
IVF
years of research
frozen and re-used
Claudy -> woman with breastcancer( normally infertile)
ART
micro-manipulations & zona drilling
Good eggs
Eggs = precious recource (1/ month)
Quality declines past 30
ovaries --> contains thousand immature eggs
Growing a baby
Embryo developement (Claudy)
Immature eggs
Maturity in Lab
Fertilized 5 eggs
Injecting sperm
Embryos in incubator
Embryo implanted
Develops in uterus
