An IVF treatment cycle

1. Controlled ovarian hyperstimulation Various protocols- Primarily FSH + inhibit spontaneous ovulation GnRH agonist or antagonist

2. Monitoring

Ultrasound/ Oestrogen Assay 3. Oocyte collection

Transvaginal, Ultrasound guided, IV sedation 4. IVF 5. Embryo transfer-

Similar to smear test

6. Freezing

Intervention to Enhance IVF
