If you’re reading this article, it’s probably because you’ve decided to seek medical advice in getting pregnant. You’re already off to a good start! Fertility specialists in specialized fertility clinics might offer further help getting pregnant.
A medical specialist dealing with the treatment of the urinary tract and urogenital system.
Uterus
A pear-shaped organ also known as the womb that supports the developing foetus throughout pregnancy. The uterus consists of: the cervical opening, the cervix and the uterine cavity. The two fallopian tubes open into the uterus.
Ultrasound
A medical imaging technique used instead of X-rays to view the reproductive organs and monitor the development of follicles.
Scrotum
The pouch of skin below the penis, which holds the testicles or testes.
Semen
The fluid released by the penis during orgasm, which helps transport sperm manufactured in the testicles.
Seminal vesicles
Two pouches located behind the male bladder, which produce part of the seminal fluid used to transport and nourish sperm.
Sperm or spermatozoa
The gamete or reproductive cell that that carries the male’s genetic information to the female‘s egg.
Sperm count
The number of sperm contained in an ejaculate. Also called sperm concentration and given as the number of sperm per millilitre. Also see Azoospermia and Oligospermia.
Sperm motility
The percentage of all moving sperm in a semen sample.
Sterility
An irreversible condition that prevents conception.
Subfertility
A condition affecting couples who have already conceived, or have had an abortion, or have produced a first child but are now experiencing difficulty in adding to their family. Also see infertility or primary infertility.
Obstetrician/Gynaecologist
A doctor who delivers babies and specialises in the treatment of female reproductive organs.
Oestrogen
A hormone that stimulates secondary female sexual characteristics and controls the course of the menstrual cycle. Oestrogen is also produced in low quantities in males.
Oligospermia
A condition when a sperm sample contains less than 20 million spermatozoa per ejaculate. Many medical conditions reduce sperm concentration. The effects may be temporary or permanent. See also Azoospermia.
Outpatient
A Person undergoing a clinical procedure that does not require admission to hospital.
Ovarian failure
The failure of the ovary to respond to hormonal stimulation from the pituitary gland because of damage to or malformation of the ovary, or a chronic disease such as autoimmune disease or ageing process.
Ovarian follicle
The structure in which eggs are nurtured to maturation. Although in general only one egg is released at a time, somewhere between 10 and 20 follicles begin the process of maturation monthly. The excess ovarian follicles are reabsorbed before ovulation occurs.
Ovulation
The release of the matured egg or ovum from the ovarian follicle.
Ovum
A matured egg.
Ovulation Induction (OI)
Medical treatment carried out to initiate ovulation.
Ovarian Hyper Stimulation Syndrome
A condition characterised by enlargement of the ovaries, fluid-retention and weight gain. May occur when the ovaries are over-stimulated during assisted reproduction.
Ovaries, Ovary
Almond-sized organ(s) located on either side of the uterus, which produce and release mature egg cells and the hormones oestrogen and progesterone.
Manual palpation
A physical examination for any genital abnormalities or any other physical signs that might be associated with conception difficulties.
Myoma
A benign tumour in the uterus consisting of muscle tissue. Myomas are often the cause of persistent infertility or miscarriage.
Micromanipulation
A variety of techniques performed in a laboratory with microscopic guidance, such as Intracytoplasmic Sperm Injection (ICSI).
Menopause
Typically diagnosed 12 months after a woman’s last menstrual cycle. Natural menopause occurs when the ovaries begin decreasing their production of the sex hormones oestrogen and progesterone and marks the end of a woman’s fertility. See premature menopause.
Menstruation or menses
Shedding of the uterine lining by bleeding. In the absence of pregnancy, this normally occurs about once every 28 days.
Miscarriage
Spontaneous loss of a viable embryo or foetus from the uterus.
Motility
The ability of sperm to swim or move. Poor motility means sperm have less chance reaching and fertilizing the egg.
Multiple pregnancy
A pregnancy with two or more foetuses.
Mumps
A viral disease of the parotid (salivary) glands. Contraction of the virus after puberty may damage sperm-producing cells in the testicles. In most cases, only one testicle is affected. Some men could suffer permanent sterility.
Idiopathic infertility
Unexplained infertility.
Infertility or primary infertility
The inability of a couple to achieve conception after a year of unprotected intercourse – six months if the woman is over 35 – or the inability to carry a pregnancy to live birth. Also see Subfertility.
Intracytoplasmic Sperm Injection (ICSI)
A single sperm is injected directly into an egg cell with microscopic guidance. If fusion takes place, the embryo is transferred into the uterus for implantation. This clinical procedure is often used in conjunction with In Vitro Fertilisation if the male partner has a very low sperm count, low sperm motility or poor-quality sperm.
Intrauterine device
(IUD): A contraceptive device consisting of a small piece of bent plastic, which prevents pregnancy by changing the environment of the uterus.
Intrauterine Insemination (IUI)
A procedure whereby sperm are deposited directly into the uterus via the cervix using a catheter.
Irregular ovulation
Menstrual cycles that vary more than a few days in length from month to month are considered irregular. Most menstrual cycles occur about every four weeks, with the normal range lasting between 24 and 35 days.
In Vivo
A process that occurs inside the body.
In Vitro Fertilization (IVF)
Eggs produced with the assistance of fertility drugs are retrieved from the woman’s body and fertilized by sperm in a laboratory environment. The resulting embryos are transferred via catheter to the uterus.
Immune system disorders
On rare occasions, an impaired immune system may regard the egg or sperm as a ‘foreign body,’ and attack it as an ‘intruder.’
Implantation
The process whereby the embryo embeds itself into the lining of the uterus. The cells from the embryo eventually connect with the mother’s blood vessels to form the placenta. See also ectopic pregnancy.
Fallopian tube
A funnel-shaped passage through which sperm are guided towards the egg, and fertilized eggs are conveyed to the uterine cavity.
Fertilization
The moment of conception when the genetic material contained in the sperm and egg combine to create an embryo. Fertilization usually occurs inside the fallopian tube. It may also occur in vitro during a clinical process. See also In Vitro Fertilization.
Fertility treatment
Any procedure used to enhance fertility or to help couples achieve pregnancy.
Fertility psychologist
A health specialist with professional qualifications in psychology and counselling relating to fertility issues.
Fibroid tumour
A benign (that is, not malignant or life-threatening) tumour made up of fibrous tissue that may form in the uterine wall. Fibroid tumours may be present without any symptoms, or may cause abnormal menstrual patterns or infertility.
Follicle
A fluid-filled sac in the ovary, which contains the egg released during ovulation. Each month a new egg matures and travels to the fallopian tube.
Follicle Stimulating Hormone
A hormone released by the pituitary gland in both sexes. In women, FSH stimulates the growth of the ovarian follicle necessary for egg production. In men, FSH stimulates and supports sperm production. Elevated FSH levels are associated with gonadotrophin failure in both men and women.
Freezing
(See Cryopreservation)
Ectopic pregnancy
A pregnancy in which the embryo implants outside the uterus and cannot be sustained.
Ejaculate
The seminal fluid discharged upon male orgasm, which helps transport sperm.
Egg retrieval
A procedure used to obtain eggs from ovarian follicles for use in In Vitro Fertilization. Retrieval may be performed during a laparoscopy procedure or via the vagina using a blunt syringe and with the aid of an ultrasound to locate the follicle in the ovary.
Embryo
The early stages of foetal growth from conception to the eighth week of pregnancy.
Embryo transfer
The process whereby an embryo is transferred into the uterus after the egg has been fertilized outside the body during a laboratory procedure.
Embryologist
A specialist involved in the various aspects of assisted reproduction laboratory procedures related to sperm, oocytes and embryos.
Endocrinologist
A medical specialist concerned with the study of hormones and infertility, having first trained as an obstetrician/gynaecologist.
Endometrial biopsy
The removal of a sample of the lining of the uterus for examination.
Endometriosis
A condition whereby cells that normally line the uterine cavity grow outside the womb, for example in the fallopian tubes, ovaries, or even the bladder or intestines. The cause is largely unknown. Scarring from endometriosis may cause conception difficulties.
Endometrium
The lining of the uterus, which is shed during the menstrual cycle. If conception takes place, the embryo implants itself into the rich vascular membrane, which nourishes the developing foetus.
Epididymis
A tightly coiled tube located above the testicles or testes, where sperm mature for fertilization.
Cervical mucus
A natural lubricant produced by the female body that aids the transportation of sperm and helps protect against infection.
Cervix
The cervix or neck of the uterus is the lower, narrow portion of the uterus where it joins with the top end of the vagina.
Chlamydia
A sexually-transmitted infection, which may be asymptomatic or cause genital inflammation and discharge, pelvic pain and fever. Untreated, chlamydia can lead to Pelvic Inflammatory Disease (PID) and fertility problems.
Chromosomes
Structures found in the nucleus of cells that contain genes and carry heredity information, such as eye colour, blood type and vulnerability to disease. Humans have 23 pairs of chromosomes. One set of 23 chromosomes is inherited from the biological mother via her egg and the other from the biological father, via his sperm. Each sperm cell contains either male or female sex chromosomes. As such, it determines the gender of the foetus. Genetic abnormalities occur when an individual is born missing a chromosome or has more copies of a chromosomal pair.
Clomiphene citrate
A prescription drug used to bring on ovulation. It comes as a tablet and is often used as an initial treatment for women with ovulation problems. Clomiphene citrate induces ovulation in 80% of women who have trouble ovulating on their own.
Conception
The moment of fertilization when the sperm meets and penetrates the egg.
Congenital abnormalities
Physical abnormalities present at birth.
Corpus luteum
A hormone-secreting mass within the ovary that forms from the remains of a follicle each time an egg is released. The hormones it produces prepare the uterus for embryo implantation. If pregnancy does not occur, the mass is shed during menstruation.
Cryopreservation
A technique used to store human tissue at very low temperatures. Embryos that are not used in an ART cycle may be preserved in this way for future use. Also known as “Freezing”.
Cryptorchidism
A condition usually detected at birth or childhood whereby the testicles fail to descend. When a male foetus develops in the uterus, his testicles normally form inside his abdomen and descend into the scrotum shortly before birth. Undescended testicles usually descend themselves by the sixth month of life, but are unlikely to descend after this period of their own accord.
Amenorrhoea
The absence of a menstrual period in a woman of reproductive age. Physiological states of amenorrhoea are seen during pregnancy and breastfeeding. Outside the reproductive years, there is an absence of menses during childhood and after menopause. See also premature menopause.
Andrologist
A medical specialist who deals with male health, particularly relating to the problems of the male reproductive system and urological problems unique to men.
Artificial Insemination (AI)
Procedure whereby sperm are deposited via the vagina into the cervix or uterus using a catheter. The technique is used to transfer donor sperm or to overcome problems with sexual performance, the interaction between sperm and mucus, or the quality of sperm.
Assisted hatching
A procedure whereby a small hole is drilled in the protective membrane of the embryo using a laser device or a dilute acidic solution to assist hatching and aid implantation.
Assisted Reproductive Technologies (ART)
A variety of procedures used to bring about conception without sexual intercourse, including In Vitro Fertilisation (IVF), Gamete Intra-Fallopian Transfer (GIFT) or Zygote Intra-Fallopian Transfer (ZIFT), Intracyto-plasmic Sperm Injection (ICSI), Microsurgical Epididymal Sperm Aspiration (MESA) and Testicular Sperm Extraction (TESE).
Autoimmune disease
A disease where the body attacks its own cells due to an overactive immune response.
Azoospermia
A complete absence of sperm in the semen. See also Oligospermia.
