Why multiple treatment cycles may be needed?

All about chance

A successful pregnancy relies on a complex combination of factors. Everything needs to be in the right place, at the right time! Even a couple without fertility issues where woman is 30 years old has only a 20% chance of achieving pregnancy in any given month. However, fertility declines with age. By the age of 40, the probability of conception in a given month falls to about 5%. Lifestyle factors or medical problems can reduce the odds still further.¹

Fertility treatments attempt to remove barriers to conception. In doing so, they restore fertility chances to what they ought to be – and sometimes beyond! In fact, data from the European IVF Monitoring Program (EIM) show clinical pregnancy rates per embryo transfer for In Vitro Fertilisation (IVF) and Intracytoplasmic Sperm Injection (ICSI) to be about 30%.² These averages are drawn from a mixture of clinics across a variety of countries. Discuss your individual chances with your doctor.

Why multiple cycles are often necessary

Even if fertility treatment successfully removes barriers to conception, the probability of conception in a given cycle is far from guaranteed. A large study followed nearly 2,000 couples trying to conceive. 57% of couples conceived within 3 months, but it took a year before 81% succeeded.³ In other words, often multiple attempts are necessary to give yourself a good chance.

Trying again

With fertility treatments most couples who succeed undergo multiple treatment cycles. In a study following couples treated with ART for 5 years, 28% conceived within a year and 62% within three years. More than 40% of couples went through four or more cycles during the length of the study.²

At some point, you and your partner may question whether you’re in need of a treatment break. It’s a personal decision that only you can make together. The Fertility Compass may help you organise your thoughts and structure the discussion.

Preparing for failure may be the key to success

Your doctors will do whatever they can to offer you the right treatment. Your job is to ensure that you and your partner remain committed to your original goal despite failures along the way. Here are some steps that might help:

Learn to stay positive during the waiting time. Discover how to maintain a positive outlook and get through your treatment cycle.
Use the Fertility Compass to identify your coping style and learn new strategies to reduce emotional strain.
Don’t put your life on hold. With a little planning, the time will pass and you’ll find the strength to continue from one cycle to the next. This week-to-week planner will help get you started.

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.
