Anovulation

When a woman does not ovulate

 

Azoospermia

When no sperm is present in semen

 

Blastocyst stage

An embryo that is 5 or 6 days old following egg collection

 

Diathermy

Electrosurgery used either as a cutting modality or else to cauterize small blood vessels to stop bleeding

 

Embryo

Fertilised egg

 

Endometriosis

Cells from the endometrium appear outside the uterine cavity, generally on the ovaries and can cause distortion and adhesions

 

Epididymis

The organ where sperm is stored

 

Fallopian tubes

Tubes which join the uterus to the ovaries

 

Fibroids

Benign (non-malignant) tumours of the uterine wall

 

Follicle

The sack in which the egg grows before ovulation. Not every follicle contains an egg

 

FSH

Follicle Stimulating Hormone which is responsible for maturing the egg

 

Gametes

Reproductive cells, either female eggs or male sperm

 

HEP B (Anti-HBc)

Hepatitis B: first antibody produced after infection with hepatitis B virus; used to detect acute and chronic infections.

 

HEP B (HBsAg)

Hepatitis B: earliest indicator of acute hepatitis B and frequently identifies infected people before symptoms appear; undetectable in the blood during the recovery period; it is the primary way of identifying those with chronic infections

 

hCG

Human Chorionic Gonadotropin is a hormone injection that triggers ovulation

 

HFEA

Human Fertilisation and Embryology Authority is the regulatory body by which all fertility clinics in the UK conform to set standards

 

HTLV

Human T-Lymphotropic Virus (HTLV) is a retrovirus associated with a weakening of the immune system which is lifelong. Some people may carry without symptoms whilst others develop cancers and other diseases, depending on the form of HTLV with which they are infected

 

Hydrosalpinx

Fluid collects in the fallopian tube

 

Hypothalamus

Area of the brain responsible for the control of the pituitary gland

 

Hysteroscopy

An inspection of the uterus using a small telescope

 

IVF

In Vitro Fertilisation

 

ICSI

Intra Cytoplasmic Sperm Injection involves injecting single sperm directly into a mature egg using a specially prepared needle

 

IMSI

Intracytoplasmic Morphologically-selected Sperm Injection is ICSI with the difference of an extremely high-powered microscope to select the sperm cells with the best quality

 

IUI

Intra Uterine Insemination involves injecting sperm using a fine catheter when a woman has ovulated

 

Laparoscopy

An inspection of the pelvis using a small telescope

 

LH

Luteinising Hormone which brings about ovulation

 

LH - RH analogue

A drug that stimulates the release of FSH from the pituitary gland

 

Myomectomy

Open surgery to remove large fibroids

 

Oestrogen / Oestrodiol  (E2)        

A female sex hormone secreted by the developing follicle

 

OHSS

Ovarian Hyper Stimulation Syndrome has varying degrees of severity and is a complication caused when there is an excessive response of the ovaries to fertility drugs

 

Ovaries

The female reproductive organs which produce female sex hormones and store and release eggs

 

Ovulation

The release of the egg from the ovarian follicle

 

Peritoneal cavity

The space that contains internal pelvic and abdominal organs

 

Pituitary gland

The gland which secretes the hormones that control ovulation

 

PCOS

Polycystic Ovarian Syndrome

 

PGAS

Pre-implantation Genetic Aneuploidy Screening is a chromosomal analysis of abnormal embryos

 

Progesterone

A female sex hormone produced by the ovaries during the release of a mature egg at ovulation

 

Prolactin

Hormone produced by the pituitary gland. High levels of prolactin cause anovulation

 

Pronuclei

Visible signs of fertilisation containing the genetic material from the male and female gametes

 

Rubella

Disease caused by the rubella virus. If the mother is infected, the baby will be born with a range of serious incurable illnesses

 

Sickle Cell screening

Blood test to check whether or not there is a possibility that a baby could inherit sickle cell disease

 

Testes

The male reproductive organs that produce sperm

 

Thalassaemia

A genetic condition affecting the blood. There are different types of thalassaemia. Depending on which type, thalassaemia may cause no illness at all or may be a serious lifelong condition requiring treatment

 

TSH

Thyroid Stimulating Hormone is produced by the pituitary gland and causes the thyroid gland to make 2 hormones: T3 and T4

 

Varicocele

Varicose veins around the vas deferens

 

Vas deferens

The tube from each testicle which transports sperm
