What Happens During an IVF Cycle? Step-by-Step

Key Clinical Summary & Takeaways

An IVF cycle unfolds across five coordinated stages over roughly 3 to 4 weeks: baseline evaluation and 8–12 days of ovarian stimulation with ultrasound monitoring, a timed trigger injection, day-care egg retrieval under sedation, 3–5 days of laboratory fertilisation and embryo culture, and embryo transfer followed by a beta-hCG blood test 12–14 days later.

Baseline scans confirm ovarian quiescence before stimulation injections begin.
Ultrasound follicle monitoring ensures safe, tailored dosing throughout stimulation.
Egg retrieval takes around 15–20 minutes under mild anaesthesia.
A beta-hCG blood test—not early home testing—gives the most reliable result after transfer.

Stages 1–2: Baseline Evaluation, Stimulation, and Trigger

Starting around Day 2 or Day 3 of the menstrual cycle, hormonal injections stimulate multiple follicles to mature simultaneously. Regular transvaginal ultrasounds and occasional blood tests track follicle growth until they reach optimal size, when a final maturation trigger injection is given 34–36 hours before retrieval.

Stages 3–5: Egg Retrieval, Lab Culture, and Transfer

Eggs are collected gently via ultrasound-guided aspiration while the male partner provides a semen sample (or frozen sperm is thawed). Embryologists fertilise the eggs via IVF or ICSI and monitor development for 3 to 5 days before fresh embryo transfer or vitrification for a planned frozen transfer.

Frequently Asked Questions

1. Do I need complete bed rest after embryo transfer?+

No. Medical guidelines advise resuming light normal daily activities after transfer rather than strict bed rest, while avoiding heavy lifting or strenuous exertion.

2. Why is it best to wait for the clinic's beta-hCG blood test?+

Testing too early at home can show false positives from trigger hormones or false negatives before implantation levels rise sufficiently.
