Environmental effects on reproduction
5 important questions on Environmental effects on reproduction
Flush: in vivo embryo?
Aspirate oocyte: in vitro embryo?
A fine needle is used to puncture the ovary, passing through the uterine wall. Before this procedure, ovarian super stimulation (superovulation) is required to encourage the growth of multiple follicles, a process essential for IVF or ICSI. Once in vitro fertilization occurs, the resulting embryo is carefully placed back into the woman's uterus.
Stress factors when using ART?
- hormones
- oxidative stress
- chemicals
- mechanical damage
- light, pH, temperature, oxygen levels
- long term and transgenerational effects
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
there are allot of risks with in vitro fertilization -> because there is a lack of environmental factors of the oviduct. -> oviduct reduce risks. which risks? (4)
- Imprinting disorders
- cardiovascular disease
- premature birth
- epigenetic changes
The ideal in vitro oviduct? (7)
- tubular structure
- polarized columnar epithelium
- can be live imaged
- easy to manipulate
- not static
- functional
- folding structure
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
