Endometriosis
Surgery is more effective than medicinal intervention for addressing infertility associated with endometriosis. Surgery attempts to remove endometrial tissue and preserve the ovaries without damaging normal tissue. In-vitro fertilization (IVF) procedures are effective in improving fertility in many women with endometriosis.
Endometrial cancer
The few contraindications to surgery include inoperable tumor, massive obesity, a particularly high-risk operation, or a desire to preserve fertility. These contraindications happen in about 5–10% of cases. Women who wish to preserve their fertility and have low-grade stage I cancer can be treated with progestins, with or without concurrent tamoxifen therapy. This therapy can be continued until the cancer does not respond to treatment or until childbearing is done. Uterine perforation may occur during a D&C or an endometrial biopsy. Side effects of surgery to remove endometrial cancer can specifically include sexual dysfunction, temporary incontinence, and lymphedema, along with more common side effects of any surgery, including constipation.
