Fertility Medicines and Injections Explained: What Each Type Does
A fertility prescription can look overwhelming: tablets, injections, gels, pessaries, vitamins, all with different names, timings and instructions. It is natural to search online to understand what each one is for. This guide explains the main types of fertility medicines and injections in plain language: what each type does, when it is used, why timing matters so much, and why these medicines should only ever be used under a doctor’s supervision.
The Most Important Point First
Please Read This
Fertility medicines are prescription medicines, chosen, dosed and timed for one person. Starting, stopping, swapping or buying them without your doctor’s advice can cause real harm, including over-stimulated ovaries (OHSS), twins or more, and missed ovulation. A product that worked for a friend, or that you read about online, may be wrong for you. If something in your prescription is unclear, ask, because that is what your doctor is there for.
मराठीत थोडक्यात: फर्टिलिटी औषधे आणि इंजेक्शन्स प्रत्येकासाठी वेगळी निवडली जातात. डॉक्टरांच्या सल्ल्याशिवाय ती सुरू करू नका, बदलू नका किंवा थांबवू नका. मित्र-मैत्रिणीला जे औषध उपयोगी पडले ते तुमच्यासाठी योग्य असेलच असे नाही. प्रिस्क्रिप्शनमधील काही समजले नसेल तर डॉक्टरांना विचारा.
हिंदी में संक्षेप: फर्टिलिटी की दवाइयां और इंजेक्शन हर व्यक्ति के लिए अलग तय किए जाते हैं। डॉक्टर की सलाह के बिना इन्हें शुरू, बदलें या बंद न करें। जो दवा किसी दोस्त को फायदा करे, जरूरी नहीं कि वह आपके लिए सही हो। प्रिस्क्रिप्शन में कुछ समझ न आए तो डॉक्टर से पूछें।

What Each Type Does
Ovulation tablets —
Used when ovulation is irregular or absent, such as in PCOS, to encourage the ovaries to release an egg. They are usually the first step before injections.
Stimulation injections —
Hormone injections, usually for one to two weeks, to help several eggs grow at once. They are monitored with scans and blood tests, and adjusted for you.
Early-release blockers —
Injections that stop your body releasing eggs before they can be collected. Timing is controlled by your clinic.
The trigger injection —
A single, precisely timed injection that completes egg maturation. Retrieval is scheduled about a day and a half later, so taking it even a little early or late can affect the result.
Estrogen —
Builds the uterine lining, especially in frozen embryo cycles and when the lining is thin.
Progesterone —
Supports the lining after transfer or IUI and in early pregnancy. It is often continued for weeks, and your clinic will tell you when to stop.
Folic acid and vitamins —
Commonly advised before conception and in early pregnancy, with extras only if tests show a need.
Why One Medicine Has Many Names
Most fertility medicines are sold by several companies under different brand names, even when the active ingredient is the same. Packs can also differ in strength, form and delivery device. That's why you shouldn't compare names with friends or online forums, assume two products are interchangeable, or switch brand or strength on your own. If a pharmacy offers a different product from the one you were prescribed, check with your doctor before using it.

Why You Shouldn't Self-Medicate
OHSS.
Stimulation without proper monitoring can over-stimulate the ovaries, causing fluid build-up that can become serious.
Twins or more.
Uncontrolled stimulation can release several eggs, raising the chance of a multiple pregnancy.
Wrong timing.
Injections like the trigger must be timed to your scans, not the calendar.
Missing the real problem.
Medicines can mask a cause, such as blocked tubes or a male factor, that needs a different treatment.
Counterfeit or badly stored products.
Some injections need careful storage. Medicines from unverified sellers may be fake or spoiled.
Interactions.
Other medicines and supplements can interfere with treatment.
Using Injections Safely
Store medicines exactly as instructed. Some need refrigeration, and some don't.
Check the expiry date, and never use a pen or needle that has been shared.
Ask a nurse to show you the technique and watch you do the first injection.
Keep a written record of every dose and time.
Dispose of needles safely in a sharps container, not loose in the bin.
If you miss or are unsure about a dose, call your clinic. Never double up on your own.
What About Supplements and "Fertility Boosters"?
Shops and websites sell many tablets, sachets and powders for fertility, for both women and men. For most of them, evidence is limited or mixed, and some are not backed by good research at all. A few vitamins have a clear role, such as folic acid before and during early pregnancy. Others are only useful if a blood test shows a deficiency. Always tell your doctor what you take, including herbal and Ayurvedic products.

Frequently Asked Questions
They are prescription medicines used to help conception: ovulation tablets, stimulation and trigger injections, estrogen and progesterone support, and vitamins such as folic acid. Each type has a specific job and is chosen, timed and dosed for the individual.
When prescribed and monitored by a specialist, they are widely used and generally safe, but they carry risks such as OHSS and multiple pregnancy if misused. That is why they need scans and blood tests, and should never be taken without medical supervision.
It isn’t advisable. The right medicine depends on your tests and cause of infertility, and taking it without monitoring can cause side effects, multiple pregnancy, or hide a problem that needs different treatment. Speak to a specialist first.
A trigger injection is a single, precisely timed injection that completes the maturation of the eggs before retrieval or IUI. Retrieval is scheduled about a day and a half later, so the timing your clinic gives must be followed exactly.
Progesterone supports the uterine lining so an embryo can implant and the early pregnancy can be maintained. It may be given as pessaries, tablets or injections, and your clinic will tell you how long to continue.
Not necessarily. Companies sell the same active ingredient under different brand names, and packs can differ in strength, form and delivery device. Never switch brand or strength without asking your doctor.
For most, evidence is limited or mixed. A few vitamins, such as folic acid before and during early pregnancy, have a clear role, and others help only if a test shows a deficiency. Tell your doctor about everything you take.
Call your clinic straight away and follow their advice. Don’t double up on the next dose on your own, because timing and dose are carefully planned and depend on your scans.
