Understanding Infertility Terms: Your Guide
- Understanding fertility terms empowers you to make informed decisions and ask better questions during treatment.
- Low AMH indicates fewer eggs but does not determine if you can get pregnant in a single cycle.
- Anovulation can occur even with regular periods and is often linked to conditions like PCOS.
- Azoospermia (no sperm in semen) and aspermia (no semen produced) are different conditions that require clear diagnosis for treatment.
- Clomiphene citrate is often the first medication used to help women ovulate before moving to more complex fertility treatments.
“I wish someone had just told me what all these words meant when we started trying.” If you’ve ever felt lost in the maze of fertility medical terms, you’re not alone. Many couples find themselves overwhelmed by strange abbreviations and complicated explanations at a time when they already feel vulnerable and anxious. It can feel like you’re being asked to learn a new language overnight, right when your emotions are at their rawest. At Malpani Infertility Clinic, we believe that clear, honest guidance is the first step to making empowered decisions about your journey.
This glossary is drawn from How to Have a Baby: Overcoming Infertility by Dr. Aniruddha Malpani and Dr. Anjali Malpani. It’s been updated with real-world meaning and relevance, so you can finally get straight answers without the jargon. If you’re already feeling the pressure of test results, treatment plans, and the emotional rollercoaster, take a deep breath. This guide is for you.
Words You’ll Hear on Your Fertility Journey, And What They Really Mean
- AMH (Anti-Müllerian Hormone): This hormone gives your doctor a sense of your ovarian reserve, or how many eggs you have left. Low AMH can mean fewer eggs, but it doesn’t predict whether you’ll get pregnant in a single cycle.
- Anovulation: When your ovaries don’t release an egg during your cycle. This can happen even if your periods are regular. Commonly linked with conditions like PCOS.
- Aspermia: No semen is produced at all, different from azoospermia, which means semen is produced but contains no sperm.
- Azoospermia: Zero sperm in the ejaculate. Sometimes, it’s a production issue; other times, there’s a blockage. There are treatments, but you need a clear diagnosis first.
- Basal Body Temperature (BBT): Your body’s temperature right after waking up. Some people track this to estimate when (or if) they are ovulating.
- Clomiphene Citrate: A medication used to encourage ovulation in women who aren’t releasing eggs. Often the first step before moving to more complex treatments.
- Controlled Ovarian Stimulation (COS): Fertility medications are used to help your ovaries produce more eggs in a single cycle, increasing your chances with IVF or IUI.
- Corpus Luteum: The spot in your ovary where an egg was released. It makes progesterone, which helps your body prepare for pregnancy.
- Embryo Transfer: A step in IVF where a fertilized egg (embryo) is placed into your uterus.
- Endometriosis: Tissue similar to the lining of your uterus grows outside it, often causing pain and sometimes making it harder to get pregnant.
- Estradiol (E2): A form of estrogen your body makes. Doctors monitor it during treatments to track how your ovaries are responding.
- Fallopian Tubes: Tubes connecting your ovaries and uterus. Eggs travel through here, and this is usually where fertilization happens. Blocked tubes can be a major cause of infertility.
- Fibroid Tumor (Leiomyoma): Non-cancerous growths in the uterus. Some women have no symptoms, while others experience pain or heavy bleeding.
- FSH (Follicle Stimulating Hormone): A hormone from your brain that signals eggs to mature in the ovaries. High FSH on certain cycle days may mean your ovarian reserve is low.
- Gamete: The medical word for an egg or sperm cell.
- GnRH (Gonadotropin-Releasing Hormone): A brain hormone that controls the release of FSH and LH, which are essential for ovulation and fertility treatments.
- HCG (Human Chorionic Gonadotropin): The hormone detected in pregnancy tests. It’s also given as an injection during some fertility treatments to trigger ovulation.
- HSG (Hysterosalpingogram): An X-ray test where dye is gently pushed into your uterus and fallopian tubes to check for blockages or shape problems.
- ICSI (Intracytoplasmic Sperm Injection): In IVF, a single sperm is injected directly into an egg. This is often used for severe male infertility.
- IUI (Intrauterine Insemination): A procedure that places specially prepared sperm directly into the uterus, giving them a head start on reaching the egg.
- IVF (In Vitro Fertilization): Eggs are removed from your ovaries, fertilized with sperm in a lab, and one or more resulting embryos are put back into your uterus.
- Luteinizing Hormone (LH): This hormone spikes (the “LH surge”) to trigger ovulation. It’s what most ovulation predictor kits measure.
- Male Factor Infertility: Infertility caused by issues with the man’s sperm count, movement, or shape. Nearly 40% of infertility cases have a male factor.
- OHSS (Ovarian Hyperstimulation Syndrome): A rare side effect of fertility drugs, where ovaries become swollen and painful. Most cases are mild and resolve on their own.
- Oligospermia: Low sperm count, which can affect the chances of fertilization.
- PCOS (Polycystic Ovary Syndrome): A hormonal imbalance that can cause irregular periods, excessive facial hair, acne, and trouble ovulating.
- PGS/PGD (Preimplantation Genetic Screening/Diagnosis): Genetic testing done on embryos during IVF to check for chromosomal or specific genetic problems before transferring them.
- Progesterone: A hormone that helps thicken the lining of the uterus after ovulation. Doctors often check this to confirm ovulation or to support early pregnancy.
- RPL (Recurrent Pregnancy Loss): Having two or more miscarriages in a row. There are many causes, and a thorough evaluation can help find possible solutions.
- Semen Analysis: A lab test to check a man’s sperm count, movement, and shape.
- Secondary Infertility: Difficulty conceiving after already having one or more children naturally.
- TTC (Trying to Conceive): The time you’re actively working towards pregnancy, whether or not you’re using treatments.
- Ultrasound: A scan that uses sound waves to look at your ovaries, uterus, and developing follicles or pregnancy.
- Zona Pellucida: The protective shell around an egg or embryo. Sometimes assisted hatching is done to help the embryo break free before implantation.
When you finally understand the words, you can start asking the right questions, and take back control of your fertility journey.
Why All This Matters When You’re Feeling Overwhelmed
Feeling lost in terminology can add to your stress. But each of these words has a real impact on the choices you’ll face. For example, knowing the difference between IUI and IVF helps you weigh your options. Understanding what an HSG checks for means you’ll be less startled if your doctor suggests it. And recognizing that male factor infertility is common can save you months of confusion or misplaced blame.
of infertility cases involve a male factor. Both partners deserve equal attention and support in testing and treatment.

Frequently Asked Questions
Q: What is the difference between IVF and IUI?
A: IVF (In Vitro Fertilization) involves fertilizing eggs and sperm in a lab, then placing an embryo into the uterus. IUI (Intrauterine Insemination) places specially prepared sperm directly into the uterus around ovulation. IVF is usually used for more complex cases or when other treatments have failed.
Q: How do I know if I have a male or female factor issue?
A: Both partners should be tested. Men usually start with a semen analysis, while women may have hormone tests, ultrasounds, and sometimes imaging like an HSG. Nearly 40% of infertility involves a male factor.
Q: What does AMH mean for my chances of getting pregnant?
A: AMH reflects your ovarian reserve (how many eggs you have left), but it does not predict if you will get pregnant in a single cycle. It helps plan treatment, but age and overall health matter too.
Q: Is PCOS always a cause of infertility?
A: PCOS can make ovulation irregular or absent, but many women with PCOS do get pregnant with the right support. Treatment options include lifestyle changes, medications, and sometimes assisted reproduction.
Q: What should I ask my doctor if I don’t understand a term?
A: Ask for a plain-language explanation and how it applies to your case. It’s your right to understand every step of your care. If you still feel confused, seek another opinion.
Q: Can unexplained infertility still be treated?
A: Yes. Even if no cause is found, there are treatment options like ovulation induction, IUI, or IVF, and many couples go on to have successful pregnancies.
Q: What is an HSG and why is it done?
A: An HSG (hysterosalpingogram) is an X-ray test that checks if your fallopian tubes are open and looks at the shape of your uterus. It can help identify blockages that could prevent pregnancy.
