Starting in-vitro fertilisation (IVF) feels a bit scary when there is planning, daily discipline and careful monitoring, all for one big day, which is the egg retrieval. The busiest time of that journey is ovarian stimulation, often called IVF stimulation.

During these ten to fourteen days you take hormone medicines that lead to multiple eggs to mature at once, giving the lab more chances to create healthy embryos.

If you are thinking of IVF, or are already undergoing the process, this article walks you through every detail so you know exactly what to expect and how to give yourself the best chance.

IVF stimulation is the period in which daily hormone injections prompt your ovaries to grow a batch of mature eggs instead of the single egg released in a natural cycle.

We can maximise the number of embryos that can be created and frozen from one retrieval.

Why does it Matter?

Any surplus embryos can be frozen, saving time, money and emotional wear in future cycles. Stimulation lets the clinic schedule retrieval and transfer precisely, rather than chasing your natural ovulation window.

A single egg limits choice and raises the risk of ending a cycle with nothing to transfer. Natural selection inside the ovary means most eggs in that month's wave quit growing after day 8–10, leaving one dominant follicle.

Medication overrides that competition so the quieter follicles keep going. The result is a cluster that is often 8–15 matured eggs if you are under 35, which offers far better embryo maths.

All protocols give you follicle-stimulating hormones (FSH ± LH) for roughly two weeks, but they differ in how they prevent premature ovulation.

(OHSS = ovarian hyper-stimulation syndrome)

You will visit the clinic every two to three days for:

• Transvaginal ultrasound: Counts and measures follicles. A follicle ≥ 17 mm usually holds a ready egg.
• Blood tests: Oestradiol (E2), LH and sometimes progesterone confirm the follicles are producing hormones in step with growth.
• Dose tweaks: Doctors adjust FSH up or down based on those readings to avoid over- or under-stimulation.

DuoStim runs a standard antagonist cycle, retrieves eggs, then restarts injections in the same luteal phase. Surprisingly, ovaries can respond twice because a second wave of follicles often emerges after ovulation.

This protocol helps:

• Ultra-low responders who typically yield < 4 eggs.
• Urgent fertility-preservation cases before chemotherapy.

Aim for a healthy-style plate rich in protein, colourful veg and healthy fats.

• Protein (1.5 g/kg) from eggs, lentils, chicken, tofu support follicle fluid.
• Good fats from olive oil, nuts, and avocado aid hormone production.
• Complex carbs like whole grains steady insulin, which influences ovarian hormones.
• Hydration is key. 2–3 L water cuts bloating and thick blood that can follow high oestrogen.

Skip anything that spikes inflammation or oestrogen metabolism.

• Trans-fats, deep-fried snacks.
• Excess caffeine (> 200 mg/day) and alcohol.
• High-mercury fish (swordfish, shark).
• Smoking or vaping—follicles sit in that bloodstream for three months.

Dos

• Walk or practise gentle yoga to boost circulation.
• Inject at the same hour each evening.
• Use a cushion-supported sleeping position if ovaries feel heavy.
• Keep a mood log; hormone swings are real.

Don’t

• Run marathons or lift heavy weights as swollen ovaries can twist.
• Take herbal supplements without clearance; some act like oestrogen.
• Miss monitoring visits even if you feel fine.

Mild bloating, twinges in the pelvis and temporary breast fullness are normal. They arise from growing follicles and higher oestrogen.

• Bloating peaks right before trigger; loose clothing helps.
• Ovary pain / lower-back ache is usually dull but sharp pain can indicate something serious.
• Fatigue, mood swings, occasional headaches are linked to hormone spikes.
• Feeling cold is common in some women.

Most symptoms fade within a week after retrieval, once hormones settle.

In India, the cost of IVF stimulation injections, which are a crucial part of the IVF process, typically ranges from ₹50,000 to ₹70,000. This cost can vary depending on the specific type of injections needed, the dosage required, and the brand of medication used.

The total cost of an IVF cycle, including stimulation injections, can range from ₹1,20,000 to ₹3,00,000. Factors:

• Dose and length of FSH course.
• Agonist vs antagonist drug brands.
• Add-ons like growth hormone or letrozole.
• Insurance coverage or pharmacy discount plans.

Clinic fees for monitoring are often bundled into the overall IVF package price, but always request a line-item quote.

The chief risk is ovarian hyper-stimulation syndrome (OHSS). Modern antagonist protocols and low-dose triggers have slashed severe OHSS rates to < 2 %.

• Early warning signs: rapid weight gain, tight abdomen, shortness of breath.
• Prevention: lower FSH doses, “freeze-all” embryos, and using a GnRH agonist trigger.
• Other risks: injection-site bruising, temporary ovarian cysts, rare ovarian torsion.

Good monitoring is your best shield, call the clinic if anything feels extreme.

Retrieval happens 34–36 hours after the trigger shot. You will rest for the day, skip driving for 24 hours because of light anaesthesia, then most people are back to desk work the next morning.

A higher egg count generally boosts the chance of at least one euploid (chromosomally normal) embryo, but quality still rules. Age, sperm factors and lab skill all weave into final outcomes.

Mild or minimal stimulation can still succeed, especially when paired with pre-implantation genetic testing.
