Difficulty getting pregnant does not always mean that IVF needs to be started right away.

Some people may continue trying naturally or consider treatments such as ovulation induction or intrauterine insemination (IUI) first. In other situations, IVF may be an appropriate option earlier.

The decision depends on factors such as age, the cause and duration of infertility, ovarian reserve, the condition of the fallopian tubes, semen parameters and the results of previous treatments.

When might IVF be considered?

1. Both fallopian tubes are blocked or severely damaged

If both fallopian tubes are blocked or severely damaged, IVF may be considered because fertilization takes place outside the body without requiring the egg and sperm to meet in the fallopian tube.

2. There is a significant sperm-related factor

IVF may be considered when sperm count, motility or other semen parameters make natural conception or IUI less likely to succeed.

In some situations, intracytoplasmic sperm injection (ICSI) may be used to inject a single sperm directly into an egg. The decision is based on the overall clinical situation rather than one semen-analysis value alone.

3. Other fertility treatments have not resulted in pregnancy

IVF may be considered after timed intercourse, ovulation induction or IUI has not resulted in pregnancy. How quickly treatment progresses to IVF depends on factors such as age, the duration and cause of infertility, and previous treatment outcomes.

4. Endometriosis is affecting fertility

Not everyone with endometriosis needs IVF. However, IVF may be considered depending on the severity of endometriosis, the condition of the ovaries and fallopian tubes, age, ovarian reserve and previous treatment outcomes.

5. Ovulation disorders have not responded to other treatments

For ovulation disorders such as PCOS, ovulation induction may be considered first. IVF may become an option if appropriate treatment has not resulted in pregnancy or if other fertility factors are also present.

6. Infertility remains unexplained

IVF may also be considered when testing does not identify a clear cause of infertility. Unexplained infertility does not automatically mean IVF is needed immediately. Age, duration of infertility and previous treatment should also be considered.

7. Preimplantation genetic testing is needed

If there is a risk of passing on certain genetic conditions, IVF may be used to create embryos for preimplantation genetic testing (PGT). Genetic counseling and specialist assessment can help determine whether PGT is appropriate.

8. Fertility preservation is needed before medical treatment

Chemotherapy, radiation therapy and some surgeries can affect future fertility. Before treatment begins, eggs may be retrieved and frozen, or fertilized to create embryos that can be frozen for future use.

When should you have a fertility evaluation?

In the absence of known fertility problems, evaluation is generally recommended after 12 months of regular unprotected intercourse when the female partner is under 35, or after 6 months when she is 35 or older. More immediate evaluation may be appropriate over age 40 or when a condition known to affect fertility is present.

A fertility evaluation may include assessment of ovulation, the uterus and fallopian tubes, ovarian function and semen when applicable. The tests needed vary according to the individual situation.

The right time for IVF is different for everyone

There is no single pathway that everyone must follow before starting IVF. Some people can try less intensive treatments first, while others may benefit from considering IVF earlier. The best approach should be based on the cause of infertility, age, previous treatment and individual reproductive goals.
