To understand a bit more about the investigations we do and their importance, we have described how a normal conception occurs.
Every month an egg is released from the ovary. This egg is sucked into the fallopian tube and it travels along the tube towards the uterus. After intercourse, sperms are deposited in the upper part of the vagina. These sperms swim up through the cervix and uterus and into the fallopian tube. In the fallopian tube, the egg and sperm meet and form the embryo which is then transported by tubal movement into the uterus where it implants in the lining called the endometrium to grow into the baby.
From the above it is clear that we need to check the following
- Whether your ovary is producing eggs- by blood tests done on the second day and the 21st day of your period to
measure your hormone levels and by doing a scan on day 2 to check the number of growing follicles
- A seminal fluid analysis – This is done to assess the sperm count or numbers, sperm movement otherwise called motility and the morphology or appearance of sperms.
- Tests to check whether the fallopian tubes are opened – called tubal patency tests. There are different types of tests which may be advised to check the tubes – a saline sonography, a hysterosalpingogram (HSG) or a laparoscopy.
- Tests to check whether the uterus is normal – by doing a scan or a procedure called hysteroscopy
- The choice of tests to be done will be discussed with you by your clinician
