When should a couple seek medical advice?

Couples should try for a minimum of one year before seeking medical advice. If either of the couple have a known medical condition that can affect fertility, or the female partner is older than 35 years medical help could be sought after 6 months of trying. These patients should be investigated and referred to a specialist centre.

What investigations do we need?

A detailed medical history and examination of both partners is undertaken.

Fertility Tests for men:

Semen analysis

Blood tests if indicated

Fertility Tests for women:

Chlamydia screen

Rubella Status

Artificial Insemination: Intrauterine insemination (IUI) is a process where sperm is washed and prepared for placement into the uterine cavity, bypassing the cervix.

In Vitro Fertilization (IVF):Is a process where eggs are collected and fertilized outside the body in a laboratory.

Intra Cytoplasmic Sperm Injection (ICSI) is a technique used to fertilise eggs by injecting a single sperm into a mature egg.

Donor egg or sperm: Third party provides either sperm or eggs with the purpose of helping the infertile couple achieve a pregnancy
