New Ovarian Stimulation Technique Offers More Cancer Patients The Chance To Preserve Their Fertility Jul 13, 2008
Nearly 77% and 73% of the oocytes were mature in the respective groups, and after intracytoplasmic sperm injection (ICSI), 70% and 75% of the oocytes were fertilised respectively. The researchers found that if ovarian stimulation was started in the second group during ovulation, then the luteal phase stopped after five days, and if stimulation was started in the mid-luteal phase, then it stopped within two days, enabling new follicles to start maturing.

Dad's Age Plays Role in Fertility Jul 8, 2008
Belloc recommends that fertility specialists suggest in vitro fertilization [IVF] or intracytoplasmic sperm injection (ICSI) -- a technique that places sperm directly into an egg -- to couples when either partner is over age 40. "These methods, although not in themselves a guarantee of success, may help couples where the man is older to achieve a pregnancy more quickly, and also reduce the risk of miscarriage," she says.
