🧬 IVF (In Vitro Fertilisation)

Painted IVF illustration. Five numbered circular vignettes in a horizontal flow connected by sepia arrows: (1) hand holding FSH+LH vial — hormone injections stimulate multiple eggs to mature; (2) ovary cross-section with eggs being collected via aspiration needle; (3) Petri dish with one egg and sperm cells approaching — fertilisation in lab; (4) Petri dish with 4-cell embryo — embryos grow 2-3 days, healthy ones selected; (5) uterus cross-section with embryo being placed by thin catheter. Parchment scroll below lists success rates (~30% under 35, ~10% over 40) and key points about in-vitro meaning and multiple-embryo trade-offs.

Figure: The 5 steps of IVF — examiners often ask about "advantages and disadvantages" linking to success rates, ethics, multiple births, emotional cost.

Steps:

  1. Woman given FSH and LH to stimulate multiple eggs to mature
  2. Eggs collected from ovaries
  3. Fertilised with sperm in a lab dish
  4. Embryos grown to a small ball of cells
  5. 1 or 2 embryos inserted into uterus

Quick Recall Flashcards

What does IVF stand for and what is it?
IVF = In Vitro Fertilisation. It is a fertility treatment where eggs are fertilised by sperm outside the body in a laboratory, then the embryo is transferred to the uterus.
What is clomifene and how does it work?
Clomifene is a drug that stimulates FSH and LH release from the pituitary gland. This promotes egg development and triggers ovulation, helping women who do not ovulate regularly.
