Accurate tests, gentle procedures

Each of the procedures below is chosen for a specific reason in your fertility plan. Dr. Rath explains why a test is needed, what it involves, and how the result will change your treatment, before it is done.

Diagnostic scan

Transvaginal Scan

A transvaginal scan is an ultrasound examination performed through the vagina, providing a clearer and more detailed view of the uterus and ovaries compared to an abdominal scan. It checks the uterine lining, the antral follicle count (an indicator of egg reserve), and conditions such as fibroids, polyps, ovarian cysts and PCOD.

Takes 10–15 minutes, no full bladder needed
Usually done early in the cycle as part of your first evaluation
Also used to monitor IVF stimulation and early pregnancy

Ovulation tracking

Folliculometry

Folliculometry is a series of transvaginal scans that track how ovarian follicles, the fluid-filled sacs that hold eggs, grow during a cycle. Measuring them helps confirm whether and when you ovulate, and gives the best timing for natural intercourse, IUI or trigger injections in IVF.

Scans start around day 8–10 of the cycle
Repeated every 1–3 days until ovulation
Essential for PCOD and ovulation induction cycles

IVF procedure

Ovum Pickup (Egg Retrieval)

Ovum pickup is a key step in IVF and ICSI. After hormonal stimulation, mature eggs are collected from the ovarian follicles using a fine needle guided by transvaginal ultrasound. The eggs then go straight to the embryology lab to be fertilised.

Performed under light sedation, about 15–30 minutes
Day-care procedure; most women go home within a few hours
Mild cramping for a day or two is common

Tubal test

Sonosalpingography (SSG)

Sonosalpingography checks whether the fallopian tubes are open. Sterile saline is introduced into the uterus while an ultrasound scan watches the fluid pass through the tubes. Blocked tubes stop the egg and sperm from meeting, so this test is important in assessing tubal factor infertility.

Done after the period ends and before ovulation
No radiation exposure
Also outlines the uterine cavity for polyps or fibroids

Advanced diagnostic

Endometrial Receptivity Array (ERA) Test

The ERA test identifies your personal window of implantation, the short period when the uterine lining is most ready to accept an embryo. A small sample of the lining is taken and analysed for gene activity, and the result guides the exact timing of a frozen embryo transfer.

Mainly advised after repeated implantation failure
Done in a mock cycle that mimics your transfer preparation
Simple outpatient biopsy taking a few minutes

Minimally invasive

Hysteroscopy

Hysteroscopy lets Dr. Rath look directly inside the uterus with a thin, lighted telescope passed through the cervix, without any cuts on the abdomen. It can diagnose and, in the same sitting, treat polyps, fibroids, scar tissue (adhesions) and a uterine septum that may affect implantation.

Diagnostic and operative in one procedure
Short anaesthesia, usually day care
Often recommended before IVF in selected women

Cervical Cerclage

Cervical cerclage is a stitch placed around the cervix to strengthen it and keep it closed during pregnancy. It is recommended for women with cervical insufficiency or a history of second-trimester loss, and helps reduce the risk of premature delivery.

Usually placed at 12–14 weeks of pregnancy
Done under anaesthesia with careful monitoring
Stitch is removed at about 36–37 weeks

Frequently asked questions

Which fertility tests will I need?

Not everyone needs every test. Most couples begin with hormone tests, a transvaginal scan and a semen analysis. Sonosalpingography, hysteroscopy or ERA are added only when your history or earlier results point to them.

Is a transvaginal scan painful?

It is usually painless, with mild pressure at most. A slim probe is gently placed in the vagina and the scan takes about 10–15 minutes. You do not need a full bladder.

How many folliculometry scans are needed in a cycle?

Typically three to five scans, starting around day 8–10 of the cycle and repeated every one to three days until the follicle is ready or ovulation is confirmed.

Is ovum pickup done under anaesthesia?

Yes, under light sedation, so you are comfortable throughout. The procedure takes about 15–30 minutes and you usually go home the same day.

When is cervical cerclage done?

Usually between 12 and 14 weeks of pregnancy in women with a history of cervical weakness or second-trimester loss. In some cases it is placed later, based on scan findings of a shortening cervix.
