In Vitro Fertilization (IVF): What You Need to Know
IVF is a complex yet life-changing fertility treatment—removing eggs, fertilising them in a lab, and transferring embryos to achieve pregnancy. Here's a clear breakdown.
What Is IVF?
IVF, or in‑vitro fertilisation, means fertilising an egg with sperm “in glass” (a lab dish) before transferring the embryo to the uterus :contentReference[oaicite:2]{index=2}. It’s the most effective assisted reproductive technology.
Why It’s Used
- Overcoming blocked or damaged fallopian tubes, low sperm count or mobility, unexplained infertility, or genetic screening :contentReference[oaicite:3]{index=3}.
- Also used for surrogacy or to avoid passing on genetic conditions :contentReference[oaicite:4]{index=4}.
Step 1: Ovarian Stimulation
You take fertility drugs (FSH, LH, GnRH agonists/antagonists) for about 8–12 days to produce multiple eggs :contentReference[oaicite:5]{index=5}. Routine bloods and scans track growth.
Step 2: Egg Retrieval
Under sedation, a specialist uses ultrasound‐guided needle aspiration via the vagina to collect follicles. Around 10–30 eggs may be retrieved :contentReference[oaicite:6]{index=6}.
Step 3: Fertilisation & Embryo Culture
In the lab, eggs are fertilised—either mixed with sperm or via ICSI (single sperm injection) :contentReference[oaicite:7]{index=7}. Embryos grow for 2–6 days before transfer.
Step 4: Embryo Transfer
A selected embryo is transferred to the uterus via a thin catheter. One or two are typically placed to reduce multiple pregnancy risk :contentReference[oaicite:8]{index=8}.
Step 5: Luteal Support & Pregnancy Test
Progesterone and possibly hCG continue to support the lining. A pregnancy test follows about 10–14 days after transfer :contentReference[oaicite:9]{index=9}.
Success Rates & Who Does Best
- Live birth rates vary by age—under 35s around 54 % per cycle; over 40 fall to 13 % or lower :contentReference[oaicite:10]{index=10}.
- Multiple cycles improve cumulative chances—up to 71–80% live birth by six cycles :contentReference[oaicite:11]{index=11}.
Fresh vs Frozen Transfers
Fresh: embryo placed immediately; Frozen Embryo Transfers (FET) allow your body to recover first. Both have similar live-birth rates, though FET may reduce prematurity and low birthweight :contentReference[oaicite:12]{index=12}.
Risks & Side Effects
- Ovarian Hyperstimulation Syndrome (OHSS): in ~30% of cycles—symptoms range from bloating to hospitalisation in severe cases :contentReference[oaicite:13]{index=13}.
- Multiple pregnancy risk: twins/triplets—risks include premature birth and low weight :contentReference[oaicite:14]{index=14}.
- Minor risks: bleeding or infection during retrieval, and rare ectopic pregnancies :contentReference[oaicite:15]{index=15}.
- There’s a slightly increased risk of birth defects—often tied to parental age rather than IVF :contentReference[oaicite:16]{index=16}.
Costs & Considerations
- Typical cost: US $12–13k per cycle; UK ~£4k–6k via NHS or private funding :contentReference[oaicite:17]{index=17}.
- Additional costs: FET storage, genetic testing, or donor gametes can add £1–2k.
Who Benefit Most
- Women under 35 with normal ovarian reserve.
- Patients with PCOS or high responders—FET may reduce OHSS risk :contentReference[oaicite:18]{index=18}.
- Individuals requiring genetic testing or surrogacy.
Alternatives & Add‑Ons
- Natural or mild IVF cycles—fewer meds, lower hormone doses :contentReference[oaicite:19]{index=19}.
- ICSI—for male infertility or egg fertilisation issues :contentReference[oaicite:20]{index=20}.
- Preimplantation Genetic Testing (PGT), time-lapse embryo selection, assisted hatching.
Real‑Life Example

FAQs
1. Does IVF damage your ovaries?
Growth medications boost follicles temporarily—long-term fertility isn’t harmed unless OHSS occurs.
2. Can I freeze eggs or embryos?
Yes—modern vitrification allows long‑term storage with high survival post-thaw :contentReference[oaicite:22]{index=22}.
3. How many cycles should I try?
Success improves across cycles—many stop after 3–6 attempts, based on individual response and preference.
4. Is it emotionally tough?
Yes—IVF can be stressful. Psychological support and peer groups are vital and often recommended.
5. Can same‑sex or single people use IVF?
Absolutely—IVF with donor eggs, sperm or surrogates helps many family structures :contentReference[oaicite:23]{index=23}.
