Am I a Candidate For IVF?

In vitro fertilization (IVF) is a technique used to help infertile couples have a baby. It is a complex clinical procedure that involves the collection of mature eggs which are combined with sperm in the laboratory. After fertilization, the eggs are implanted into the woman’s uterus. It is a time-consuming and invasive procedure, which takes around 2 weeks for the completion of a single fertilization cycle.

Specialized Care for Endometriosis

Endometriosis is a common gynecological problem affecting women of reproductive age. It occurs when the tissues of the uterus start growing on surfaces of other organs in the pelvis. Endometrium may grow on ovaries, fallopian tubes, an outer surface of the uterus, pelvic cavity lining, vagina, cervix, vulva, bladder or rectum. Patients may experience painful cramps in the lower abdomen, back or in the pelvis during menstruation, heavy menstrual bleeding, painful bowel movements or urination and infertility.
