WEDNESDAY, Jan. 4 (HealthDay News) — The birth rate for twins in the United States has jumped by 76 percent since 1980, government health officials reported Wednesday.
Most of the increase appears linked to new fertility treatments that make it easier for older women to conceive, according to a report released by the U.S. Centers for Disease Control and Prevention.
THURSDAY, Oct. 27 (HealthDay News) — Women who undergo ovarian stimulation to produce extra eggs for in-vitro fertilization (IVF) are at increased risk for a type of growth known as “borderline ovarian tumors,” new research suggests.
Borderline ovarian tumors are typically not aggressive, according to the U.S. National Cancer Institute. Even if the tumor does spread, the vast majority of women survive borderline ovarian tumors.

WEDNESDAY, Aug. 17 (HealthDay News) — Researchers have found an antibody that might someday be useful in identifying women who have a higher risk of ovarian cancer, or possibly diagnosing early ovarian cancer.
This particular antibody, which was detected in blood, develops as an immune system response to a protein called mesothelin. This protein is present in advanced ovarian cancer. Although mesothelin is found in normal tissue, it’s found in abundance in ovarian cancer cells.
THURSDAY, Aug. 11 (HealthDay News) — There’s no strong evidence that taking aspirin while undergoing in vitro fertilization (IVF) improves a woman’s chances of becoming pregnant, researchers say.
Routine use of aspirin during IVF treatment is controversial. Proponents believe that aspirin may improve blood flow to the womb and ovaries, but there are concerns that taking aspirin may cause pregnancy complications or miscarriage.
WEDNESDAY, June 15 (HealthDay News) — Weight-loss surgery may reverse a common cause of infertility in women, a small, new study suggests.
Polycystic ovarian syndrome (PCOS) is a hormonal imbalance that affects up to 10 percent of women of child-bearing age. An estimated one-third to one-half of women with PCOS are overweight or obese, according to the American Society for Metabolic & Bariatric Surgery (ASMBS).
THURSDAY, May 26 (HealthDay News) — Caffeine, a known stimulant, has been shown to cause rapid heart rate, nausea, anxiety and depression. Now, new research reveals that caffeine consumption may make it harder for a woman to get pregnant.
By analyzing fallopian tubes in mice, researchers found that caffeine interferes with muscle contractions that help eggs travel from the ovaries through the fallopian tubes and into the womb — a process critical for a successful pregnancy.
TUESDAY, May 17 (HealthDay News) — A gene variation that causes faulty cholesterol regulation also appears to affect production of the pregnancy hormone progesterone and may be a reason why some women can’t get pregnant, researchers say.
The Johns Hopkins University team looked at more than 200 infertile women who were undergoing in vitro fertilization (IVF) and identified nine who had the variation of the scavenger receptor class B type 1 (SCARB1) gene.
WEDNESDAY, May 11 (HealthDay News) — It may be possible to assess a man’s fertility by checking his “anogenital distance,” the gap between his scrotum and anus, a new study suggests.
Previous studies in animals have shown that anogenital distance is an important measure of genital development and may be shorter in males with abnormal development and dysfunction of the testicles, the Baylor College of Medicine researchers explained.
WEDNESDAY, May 11 (HealthDay News) — Retrieving about 15 eggs from a woman’s ovaries in a single in vitro fertilization (IVF) cycle offers the best chance of achieving a live birth while avoiding complications from fertility medications, according to a new study.
Researchers analyzed more than 400,000 IVF cycles in the United Kingdom between 1991 and 2008 and found a strong association between live birth rates and the number of eggs retrieved in one cycle.

FRIDAY, March 4 (HealthDay News) — New research contends that the distance between the posterior base of the scrotum and the anus can predict the strength of a man’s sperm population.
Men who have a shorter perineal length, also known as the anogenital distance (AGD), have lower sperm counts, poorer quality sperm, lower sperm concentrations and lower motility, the study has found.
