2. First 2 months of life
breast development?
3. Puberty
- Estrogen:
Induces Ductal System
Breast development during development
menstruation - Progesterone:Induces
Lobular-Alveolar development
What is Lactogenesis? The initiation of milk production
How many stages of Lactogensis are 4
there?
What stages of Lactogenesis occur
1 and 2
during pregnancy?
Ductal and Lobular-Alveolar systems
grow at an accelerated rate
(influenced by hormones)
Lactogenesis 1 - breasts enlarge
- highprogesterone levels cause
an increase in alveoli
- colostrum begins to produce in the
alveoli
When does Lactogenesis 1 occur? around 16 weeks
, The placenta is released from the
uterus and progesterone levels drop
Lactogenesis 2 - this causes the alveolar cells to
begin to
release milk and allows them to
continue to produce more milk
How long does Lactogenesis 2 last? 2-4 days
