Sometimes, in vitro fertilization is offered as a primary treatment for infertility in women over age 40. In vitro fertilization can also be done if you have certain health conditions. For example, in vitro fertilization may be an option if you or your partner has:

• Fallopian tube damage or blockage

Fallopian tube damage or blockage makes it difficult for an egg to be fertilized or for an embryo to travel to the uterus.

• Ovulation disorders

If ovulation is infrequent or absent, fewer eggs are available for fertilization.

• Endometriosis

Endometriosis occurs when tissue similar to the lining of the uterus implants and grows outside of the uterus – often affecting the function of the ovaries, uterus and fallopian tubes.

• Uterine fibroids

Fibroids are benign tumours in the uterus. They are common in women in their 30s and 40s. Fibroids can interfere with implantation of the fertilized egg.

• Previous tubal sterilization or removal

Tubal ligation is a type of sterilization in which the fallopian tubes are cut or blocked to permanently prevent pregnancy. If you wish to conceive  after tubal ligation, in vitro fertilization may be an alternative to tubal ligation reversal surgery.
