A

Washed sperm are injected into uterine cavity during natural menstrual cycle

+++
Using FSH/LH ovulation induction

42
Q

Cervical/sexual/male factors

43
Q

Pros of IUI (2)

A

Liver BR = 5-10%

Cheaper than IVF

44
Q

Cons IUI (3)

A

Lower success rate IVF
Tubes MUST be patent
Natural IUI req reg/normal cycles

45
Q

What are the 5 steps to IVF

A

1 - give RnRH analogue –> downregulation LH/FSH
2 - Re-add FSH (Menopur) –> lots of follicle recruitment
3 - Ovulation collection when 15-20mm + hCG (for LH)
36h after hCG added - USS + needle to suck eggs out
4 - Fertilation + culture 3-5days (incubator) –> blastocysts
5 - embryo transfer + progesterone pessaries 8w to support luteal phase

46
Q

Success rate 25%

Fallopian tubes don’t need to be patent
