Insemination: directly inserting sperm into the womb to achieve pregnancy

Insulin: a hormone produced by the pancreas that allows the body to use sugar (glucose) which is converted from carbohydrates into energy. It stops the blood sugar level from getting too high or too low

Intrauterine insemination (IUI):

Immunological/immunology: a branch of medicine dealing with the immune system, the complex network of cells, tissues and organs that defend the body against germs

Implantation failure: when an embryo fails to implant in the womb. Recurrent implantation failure is diagnosed when a pregnancy has not been achieved after at least three cycles of in vitro fertilisation (IVF)

Laparoscopy/laparoscopic surgery: a type of minimally invasive procedure where a thin tube with a camera (laparoscope) is inserted through a small cut in the abdominal wall to diagnose and treat a number of conditions

Libido: sex drive

Luteinising hormone (LH): essential for fertility, this hormone regulates the ovaries in women and testes in men. It is needed to produce oestradiol and is also responsible for ovulation after which it stimulates the production of progesterone if an egg is fertilised. High levels of LH can be associated with polycystic ovary syndrome (PCOS)

Menstrual cycle: the cycle of changes affecting the ovaries and womb to prepare for ovulation, fertilisation of an egg, and pregnancy

Night sweats: excessive sweating associated with hormonal imbalances, especially during the menopause when it is caused by lower levels of oestrogen

Obesity: describes someone who is overweight with excess body fat which can have a negative effect on their health

Obstetric: branch of medicine that deals with pregnancy and the period before and after childbirth (antenatal care)

Oestradiol: essential for ovulation, as well as for the thickening of the lining of the womb (endometrium) so that an egg can attach to it if it is fertilised. Oestradiol is made by the ovaries and levels decrease with age, particularly during the menopause

Oestrogen: a female hormone produced in the ovaries along with progesterone. It is essential for female characteristics, sexual function, bone health, ovulation and reproduction

Ovarian cyst: a fluid-filled sac that forms on the ovary

Ovary: one of a pair of ovaries, women’s reproductive glands; they are involved in producing the sex hormones (including oestrogen and progesterone) that control reproduction. They contain follicles, which can develop into eggs to be released each month during the menstrual cycle, ready to travel down the fallopian tube for fertilisation by sperm to develop into an embryo

Ovulation: this is when the follicle releases an egg, which travels down the fallopian tube to be fertilised by sperm

Ovulation predictor kit: a home kit to identify when the woman is most fertile. It detects a surge in the luteinising hormone (LH), which happens about 36 hours before ovulation

Pessaries: (for fertility treatment) a small soluble block of medication that can be inserted into the vagina or anus

Polyps: small growths on mucous membrane, often in the lining of the womb (endometrium) or the cervix

Pregnancy hormone (hCG): see hCG

Pregnancy test: this measures the amount of hCG (pregnancy hormone) in the urine

Premature labour: going into labour before 37 weeks of pregnancy

Progesterone: produced in the ovaries, this hormone helps the body to prepare for conception and pregnancy, as well as regulating periods

Prolactin: produced by the pituitary gland, this hormone enables milk production as well as other functions including playing an essential role in the metabolism and regulating the immune system. Very high levels can decrease the production of oestrogen and affect the menstrual cycle

Quarantined: separated and isolated for a while to check for disease

Radiotherapy: a treatment using high energy radiation, often used in cancer therapy

Recurrent implantation failure: see implantation failure

Scrotum: a small sac of skin and muscle that contains the testicles

Self-insemination: to inject semen into the vagina in order to achieve a pregnancy

Semen: fluid secreted by the male reproductive organs which contains sperm

Speculum: a medical instrument that holds the vagina open during an internal examination

Sperm bank: a place where semen is stored to be used in artificial insemination
Sterilisation (vasectomy): a procedure to cut the vas deferens (the tube that takes sperm from the testes to the penis) so sperm cannot be ejaculated during sex. It is a permanent type of contraception

Stroke: an interruption of blood supply to the brain, resulting in lack of oxygen and the sudden death of cells in one area of the brain

Testes: male reproductive glands that produce and store sperm

Testicular tissue: tissue surrounding the testes

Testosterone: low levels of this male hormone suggest a man may have decreased fertility

Transvaginal ultrasound scan: used to carry out a pelvic ultrasound scan. You will be asked to empty your bladder first, before lying on your back with your legs apart where they can rest in specially designed holders. The slim ultrasound probe will then be covered and lubricated before being gently inserted into the vagina. The image appears on a screen and the probe is moved gently about to identify the individual structures so that measurements and images can be taken

Type 2 diabetes: a long-term condition that affects the body’s ability to break down (metabolise) sugar. It may be treated by modifying the diet or by being prescribed insulin

Ultrasound scan (pregnancy): a scan that uses sound waves to check the health of a baby in the womb and detect any abnormalities

Vasectomy: see sterilisation

Vitrification: a type of technology used at the Agora to freeze embryos, which are kept in liquid nitrogen storage at -196°C. At this temperature all biological activity in the embryo stops and it will remain stable for many years. Current regulations allow us to store embryos for up to 10 years and these can be used at a later date in Frozen Embryo Transfer (FET) cycles

Vulva: the external genital organs of a woman

Womb (uterus): the organ in a woman where babies are conceived and grow until birth
Zift technique: when a fertilised embryo is transferred into the fallopian tube instead of the womb
