Starting fertility treatment can feel like learning a new language. From acronyms like AMH and ICSI to phrases like “luteal phase” or “blastocyst transfer,” the medical jargon can be overwhelming. At Demeter Fertility, we believe in clear, compassionate communication. Here’s a simple glossary to help you understand the most common fertility terms and acronyms.
Common Acronyms
IVF (In Vitro Fertilisation)
A process where eggs are collected, fertilised with sperm in a lab, and the resulting embryo is transferred to the uterus.
IUI (Intrauterine Insemination)
A fertility treatment that places sperm directly into the uterus during ovulation.
AMH (Anti-Müllerian Hormone)
A hormone that gives an indication of your ovarian reserve (how many eggs you have left).
FSH (Follicle Stimulating Hormone)
A hormone involved in egg development. Higher levels can suggest a reduced ovarian reserve.
LH (Luteinising Hormone)
A hormone that triggers ovulation and supports early pregnancy.
PCOS (Polycystic Ovary Syndrome)
A hormonal condition that can affect ovulation and fertility.
FET (Frozen Embryo Transfer)
A cycle where a previously frozen embryo is thawed and transferred into the uterus.
ICSI (Intracytoplasmic Sperm Injection)
A form of IVF where a single sperm is injected directly into an egg. Often used when there are sperm-related issues.
General Fertility Terms
Egg Collection
A procedure where mature eggs are retrieved from the ovaries, usually under sedation or local anaesthetic.
Embryo Transfer
Placing a fertilised embryo into the uterus in hopes of achieving pregnancy.
Luteal Phase
The second half of your menstrual cycle, after ovulation and before your next period. It’s when implantation occurs.
Ovarian Reserve
A term describing the quantity (and to some extent quality) of your remaining eggs.
Blastocyst
An embryo that has developed for 5–6 days after fertilisation. Often used for embryo transfers due to its higher implantation potential.
Antral Follicle Count
An ultrasound scan that counts the small follicles on your ovaries and helps estimate your ovarian reserve.
