Abstract
Endometriosis is a condition in which tissue that lines the uterus grows outside the uterus. Patients with endometriosis often experience pelvic pain with menstrual periods and sometimes also infertility. Sometimes it is mistaken for pelvic inflammatory disease or ovarian cysts. This condition is a contraindication for pregnancy. This is a case report of a 37-year-old female who came to in vitro fertilisation (IVF) with a history of infertility of 14 years and was diagnosed with Grade 4 endometriosis on diagnostic ultrasonography-guided hysterolaparoscopy. After many trials of intrauterine insemination she was advised to go for IVF, and that not by obtaining her own ovum. The donor's egg and male partner's sperm were used for the IVF. The fertilised zygote was then implanted in the patient's uterus.
