Key Fertility Terms Explained: Your IVF Glossary
AMH: stands for Anti-Mullerian Hormone. This is a protein hormone produced by cells within the ovary. Understanding your AMH level tells you how good your egg reserve is and this gives the doctor an indication of how fertile you are. AMH levels are naturally lower in older women (particularly over the age of 40) and higher in women with Polycystic Ovaries (PCO) or Polycystic Ovary Syndrome (PCOS).
FSH: is Follicle Stimulating Hormone. FSH is a hormone produced by the pituitary gland. This stimulates the growth of follicles in the ovary before the release of an egg. A high reading of FSH can be an indication of a poor ovarian reserve.
What we measure
Blood-flow: The blood flow to your uterus, ovaries and follicles gives you an idea of how good your ovarian-reserve is. A cell in the body that has good blood flow is likely to be a healthy cell; it has received a good supply of oxygen and nutrients. By looking at blood flow, we can see which eggs might be of better quality.
Egg-reserve/ovarian-reserve: is the term that is used to determine the capacity of the ovary. The ovary houses the egg cells that are most likely to fertilise and result in a healthy pregnancy.
Follicle count: We count follicles that are between 2-6mm in the ovary. This is because if you have plenty of follicles of this measurement when you come in for your scan, this indicates a good ovarian reserve.
We measure each of these in our Fertility Assessment and our Initial Scan and Consultation
Fertility treatments and procedures
AI: stands for Artificial Insemination. This is a treatment that involves directly inserting sperm into a woman's womb.
Egg Freezing: Egg freezing is a method of fertility preservation, which allows women to freeze eggs for later use when they might like to start a family.
Embryo Freezing: once the egg and the sperm have successfully fertilised, we can freeze the embryo created. We use a freezing method called vitrification to rapidly freeze the embryo to ensure the best preservation. This will then be inserted back into the womb later.
Endometrial Scratching: a procedure that can be carried out before the embryo transfer, where the lining of the womb is gently scratched to help the embryo to implant more successfully.
HyCosy: Hysterosalpingo-contrast-sonography (usually called HyCoSy), is a straightforward procedure which is used to look at the fallopian tubes and to check for abnormalities of the uterus and ovaries. This is where a dye is passed into the uterus, and the doctor tracks it using an ultrasound scan.
Hysteroscopy: Hysteroscopy is a procedure where a very thin telescope camera is used to view the inside of your womb. It is used to investigate different conditions of the uterus such as polyps, fibroids, septum or scarring inside the uterine cavity.
ICSI: stands for Intracytoplasmic Sperm Injection. This is where an individual sperm cell is inserted directly into the egg cell.
Implantation: after the successful fertilisation of the egg and the sperm, forming an embryo, the embryo is placed back into the womb.
IUI: IUI involves directly inserting specially washed sperm into a woman’s womb at the most fertile point of her cycle. Doctors use hormone blood tests and monitoring scans to keep track of the cycle and pinpoint the time at which ovulation occurs.
IVF: stands for In Vitro Fertilisation, it involves the fertilisation of an egg and a sperm outside of the body. ‘In vitro’ means ‘in glass’.
Semen Analysis: Our detailed semen analysis looks at the density, morphology and mobility of your sperm.
Sperm Freezing: we perform Sperm Freezing through vitrification. The sample will be frozen by our embryologists using vitrification technology, an advanced fast-freezing. Once frozen, the sperm can be thawed at your disposal, with very high survival rates from thawing.
Common Fertility Problems
Azoospermia: this is when there is no sperm present in a man’s ejaculate. This can be due to blockage in the tubes that the sperm is transported through, a vasectomy, low or no sperm production in the testicle.
Endometriosis: is a common condition in women where tissue that behaves like the lining of the womb (endometrium) is found in other places such as: the fallopian tubes, the ovaries, and in or around the bladder or bowel.
Low Ovarian Reserve/Low AMH: This means that there are low numbers of developing cells in the ovaries. This indicates that your fertility status is lower, something that declines with age.
Polycystic Ovarian Syndrome (PCOS): This is where the levels of the hormones estrogen and progesterone are out of balance. This leads to the growth of ovarian cysts.
Tubal Disease: a disease where women have blocked or damaged fallopian tubes.
Thyroid Disease: Infertility can be caused by diseases of the thyroid, when it is under- or over-active. Women with a thyroid disease will be given tailor-made treatment under the care of our experienced doctors.
Embryoscope: is an incubator that has the right conditions for a healthy embryo to develop in the laboratory. It has a special time lapse system with a camera that continuously captures images and records them as the embryo develops, which can be used in combination with our unique CAREMaps algorithm analysis to significantly increase success rates.
Ultrasound Scan: this is the advanced transvaginal scan that we use to assess your ovarian-reserve. This will check how healthy your uterus, ovaries and follicles are by examining the blood flow to each of them.
We hope that our IVF glossary will answer a few of the questions you may have about fertility and our services. However, if you have any more questions for us, or you would like to book in for an Initial Scan and Consultation please do get in touch.
