Ovulation induction - fertility drugs, properly monitored.

Letrozole, clomifene or gonadotrophin injections to restart ovulation - every cycle planned by a consultant in reproductive medicine and tracked with ultrasound, so the dose is right and the twin risk stays low.

Indicative pricing

What private ovulation induction costs in the UK.

Indicative per-cycle ranges across our partner fertility units.

In short

£500–£1,200, including follicle-tracking scans.

Procedure Indicative range
Fertility consultation (reproductive medicine) £220–£400
Baseline fertility work-up (bloods + scan) £400–£800
Letrozole or clomifene cycle, fully monitored £500–£1,200
Gonadotrophin (injectable) cycle, monitored £1,200–£2,500
Follicle-tracking scan (single) £150–£250
Intrauterine insemination (IUI) add-on £800–£1,600
Laparoscopic ovarian drilling (if drugs fail) £4,500–£7,500

Prices vary by clinic, by drug (tablets versus injections), and by how many scans your response needs. Gonadotrophin cycles and IUI add-ons are always the top of the range.

The problem

The right drug, a monitored cycle, and an honest exit plan.

Ovulation induction goes wrong in predictable ways - unmonitored tablets, cycles repeated long past the point of usefulness, and IVF conversations delayed. We fix all three before you start.

  • No tablets without scans

    Unmonitored clomifene is how twin and triplet pregnancies happen.

  • Letrozole first for PCOS

    Trials show better live-birth rates than clomifene in anovulatory PCOS - yet plenty of clinics still reach for the older drug by habit.

  • Six cycles, then a real conversation

    If six well-run ovulatory cycles have not worked, more of the same rarely will. We plan the next step - IUI, drilling or IVF - before you get there.

When it helps

When ovulation induction is the right step.

The situations we see most, plus the one red flag that means endocrine review rather than fertility drugs.

  • PCOS with absent or irregular ovulation

    The single most common indication. Letrozole is now first-line for anovulatory PCOS in UK practice.

  • Irregular or absent periods

    Oligomenorrhoea or amenorrhoea with normal oestrogen - WHO group II anovulation responds well to tablets.

  • Unexplained subfertility

    Sometimes combined with IUI after a full work-up - though for many couples IVF is the better-evidenced route.

  • Hypothalamic anovulation

    Low body weight, over-exercise or stress switching ovulation off - gonadotrophins or pulsatile GnRH after lifestyle work.

  • After clomifene resistance

    No ovulation after adequate clomifene dosing - options include letrozole, gonadotrophins or ovarian drilling.

  • Timed cycles for IUI

    A gently stimulated, monitored cycle makes insemination timing precise - one or two follicles, never more.

  • Hyperprolactinaemia or thyroid disease

    Treat the cause first - a prolactinoma or hypothyroidism often restores ovulation without fertility drugs at all.

  • Red flag: possible premature ovarian insufficiency

    Absent periods with high FSH and menopausal symptoms under 40 needs specialist endocrine review - ovulation induction is rarely the answer.

Procedure options

The drug - and the plan around it - depend on why you are not ovulating.

What each option involves - from first-line tablets through injections, ovarian drilling and the honest move to IVF.

  • Letrozole

    An aromatase inhibitor, now first-line for PCOS. Taken for five days early in the cycle; higher live-birth rates than clomifene in anovulatory PCOS.

  • Clomifene citrate

    The long-standing tablet option. Effective and cheap, but with a slightly higher multiple-pregnancy rate and a thinner endometrium in some women.

  • Gonadotrophin injections

    Daily FSH injections for clomifene- or letrozole-resistant cases and hypothalamic anovulation. Needs close scan monitoring - the strongest drugs, and the ones most likely to over-respond.

  • Metformin (adjunct)

    For PCOS with insulin resistance. Modest effect alone; sometimes combined with letrozole or clomifene, alongside weight and lifestyle work.

  • Pulsatile GnRH

    A small pump mimicking the brain’s natural signal - the physiological fix for hypothalamic amenorrhoea, with near-normal singleton pregnancy rates.

  • Laparoscopic ovarian drilling

    A day-case keyhole option for clomifene-resistant PCOS - restores spontaneous ovulation in roughly half of women, without multiple-pregnancy risk.

  • Ovulation induction + IUI

    A monitored, gently stimulated cycle with washed sperm placed in the uterus at ovulation - for mild male factor, donor sperm or unexplained subfertility.

  • Moving on to IVF

    If six well-run ovulatory cycles have not worked - or age, tubal disease or semen results argue for it - IVF is the honest next step, and we say so early.

Safety and recovery

What to expect afterwards - honestly.

Ovulation induction is safe when it is monitored. The things worth understanding are multiple pregnancy, over-response, and knowing when to stop.

  • Multiple pregnancy is the main risk

    Twins occur in roughly 5–8 percent of clomifene pregnancies and more with gonadotrophins. Monitoring and cancelling over-responding cycles is how good clinics keep this low.

  • Ovarian hyperstimulation (OHSS)

    Mostly a gonadotrophin risk - bloating, nausea, rapid weight gain. Mild forms are common; severe OHSS is rare in monitored ovulation induction but needs same-day review.

  • Side effects of the tablets

    Hot flushes, mood swings, headaches and visual disturbance (clomifene - stop and call if this happens). Letrozole tends to be gentler on the endometrium.

  • Cycle cancellation is a safety feature

    If three or more mature follicles develop, the cycle is cancelled and you are advised to avoid conception that month. Frustrating - and exactly what protects you.

  • Time limits matter

    UK practice caps clomifene or letrozole at around six ovulatory cycles. Beyond that, continuing offers little and delays more effective treatment.

  • Red flags during a cycle

    Severe abdominal pain, breathlessness, vomiting or reduced urine output during stimulation needs the clinic the same day, or A&E out of hours.

Reading your cycle summary

Your cycle summary in four parts. Read the last one first.

Whichever drug you used - letrozole, clomifene or injections - the summary your consultant sends after each cycle keeps to the same shape.

Frequently asked

Everything we get asked about ovulation induction.

Quick answers on letrozole versus clomifene, success rates, twins, cost and the NHS pathway.

  • What is ovulation induction?

    Ovulation induction uses medication - usually letrozole or clomifene tablets, sometimes gonadotrophin injections - to make the ovaries release an egg in women who ovulate rarely or not at all. Cycles are monitored with ultrasound so the dose can be adjusted and over-response caught early.

  • How well does it work?

    For anovulatory PCOS, around 70–80 percent of women ovulate on letrozole or clomifene, and roughly 40–60 percent conceive within six ovulatory cycles. Success depends heavily on age, weight, duration of subfertility and whether other factors - tubes, sperm - are normal.

  • Letrozole or clomifene - which is better?

    For PCOS, letrozole. Trials show higher ovulation and live-birth rates than clomifene, with a thicker endometrium and a slightly lower twin rate. Clomifene remains a reasonable option and is sometimes preferred for non-PCOS anovulation.

  • What are the chances of twins?

    Roughly 5–8 percent with clomifene, a little lower with letrozole, and higher with gonadotrophins if cycles are not carefully monitored.

  • How much does private ovulation induction cost in the UK?

    A fully monitored letrozole or clomifene cycle is typically £500–£1,200 including scans; gonadotrophin cycles run £1,200–£2,500. Add £220–£400 for the initial consultation and £400–£800 for baseline tests. Adding IUI costs £800–£1,600 per cycle.

  • Can I get ovulation induction on the NHS?

    Yes - NICE recommends it for anovulatory subfertility, and most NHS trusts offer letrozole or clomifene with some monitoring. Waits for the initial fertility clinic appointment vary from a few weeks to several months by area, and monitoring intensity varies too. Many couples go private for speed and per-cycle scanning, then return to NHS or private IVF if needed.
