Infertility Causes & Information

Finding the right treatment to suit your situation can be daunting.

In our society 5-10% of couples have varying degrees of infertility.

Common Causes of Infertility

Tubal & Uterine causes

Cervical mucous

When do I seek advice about our fertility?

If any of these apply to you then please make an appointment to see us at Coastal IVF as soon as possible.

  1. Have you been trying to conceive for more than 6 months?
  2. Have you been diagnosed with endometriosis?
  3. Has your partner had a vasectomy?
  4. Are you over the age of 35?
  5. Is your menstrual cycle more than 30 days or less than 26 days?


  • over the age of 35 should not put off investigation of their fertility more than 6 months
  • over the age of 38 should seek help immediately
  • who do not menstruate regularly are often not ovulating and should seek advice early

Did you know? Failure to conceive is often the only symptom of endometriosis.

Early investigation means early diagnosis and more effective treatments.

Normal Conception

In a couple with normal fertility, intercourse at the time of ovulation results in a pregnancy rate of approximately 16%.

This is the best nature can do and all reproductive technology pregnancy rates need to be assessed with this figure in mind.

We are therefore not a highly fertile species.
Conception occurs following intercourse at the time of ovulation.

Sperm tracks through the cervical mucous, the uterus and into the fallopian tube where the oocyte (egg) is situated. It is released from the ovary at the time of ovulation and is swept up by the end of the fallopian tube and drawn into it.

A sperm penetrates the egg and fertilisation occurs with a mixture of male and female chromosomes.

A cell is formed which then divides to form a multi-cell structure called an embryo. This remains in the tube for 4 days and then enters the uterus where it implants into the lining.

Approximately 85% of pregnancies then continue normally and approximately 15% of pregnancies will miscarry due to some genetic defect within the embryo. Conception in normally fertile couples can be enhanced by a healthy lifestyle and inhibited by cigarette smoking, excessive alcohol consumption and drug ingestion.

The younger a couple, the more fertile they will be and the older, (the woman especially) the less fertile.

The causes of infertility vary, and treatments offered can be simple or more complex.
This means the success rates vary significantly depending on the individual couple’s problems.
At Coastal IVF we offer hope and possible success of pregnancy with an IVF or fertility cycle tailored to your need.


The reality unfortunately is that many of these techniques may require multiple attempts. This alone can be difficult for a couple to cope with.
An important factor of our clinic is the availability of counselling and support during these emotional times – giving each individual assessment as required.

The information our website endeavours to give an insight into our IVF facilities and hopefully a better understanding of the management of infertility.

Please feel free to discuss any queries you may have with our Nurse Coordinator.
We wish you all hope and success of parenthood.
