| Term | Definition |
| Laparoscopy | A surgical procedure in which a telescope-like device is inserted through a small incision near the navel to view the pelvic cavity, the ovaries, fallopian tubes, and uterus. |
| Leuprolide Acetate | See Lupron. |
| LH | See Lupron. |
| LH Surge | A spontaneous release of large amounts of luteinizing hormone (LH) during a woman's menstrual cycle. This normally results in the release of a mature egg from a follicle (ovulation). Ovulation Predictor Kits (OPKs) measure LH in the urine. |
| Lupron | A hormonal medication that can create a pseudo menopause. A chemical similar to GnRH, it first stimulates the female hormones, then suppresses a woman's secretion of FSH and LH. Concurrent treatment with Lupron tends to increase the number of follicles, oocytes (eggs), and embryos during a cycle, decreasing the risk of a cancelled cycle. |
| Lupron "Down Regulation" | A treatment with Lupron that takes advantage of the suppression of natural hormone (LH and FSH) secretions. Used before injection of gonadotropins to stimulate follicular development. |
| Lupron "Flare" | A treatment with Lupron that takes advantage of the initial stimulation and rise or "flare" of the woman's LH and FSH levels after the start of Lupron administration, lasting one to three days. |
| Luteal Phase | The days of a menstrual cycle following ovulation and ending with menses (usually lasting between 12 and 14 days). |
| Luteinizing Hormone (LH) | A hormone that causes the ovary to release a mature egg (ovulation). In the male, LH stimulates testosterone production. LH is secreted by the anterior pituitary. In the female, LH stimulates progesterone production after ovulation has occurred. Luveris is the only commercially available LH. |
