Ultrasound could help couples undergoing IVF

15.03.2007
Ultrasound-based tests allowing women undergoing in-vitro fertilization (IVF) to count their chickens before they've hatched may provide alternatives to the hormone-based tests used today. Less costly and invasive than the current ovarian reserve tests, clinicians may in future consider using ultrasound scans of a woman's ovaries to predict her ovaries' response to IVF.

Research published today in Reproductive Biology and Endocrinology details how Janet Kwee et. al. from Vrije Universiteit Medical Centre in Amsterdam, The Netherlands studied 110 women aged 18-39 who had difficulty conceiving. She counted the number of antral follicles, small egg-bearing ovarian follicles about 2-10 mm in diameter, with transvaginal sonography (ultrasound).

Kwee compared the follicle count with ovarian volume with the results from ovarian reserve endocrine tests. The antral follicle count was an effective predictor of the number of eggs the patient would ultimately produce when her ovaries had been stimulated during IVF treatment.

A test that can be administered before IVF that indicates ovarian response might be used to counsel patients as to their chances of success, and help clinicians decide the starting dose of hormones used to stimulate the patient's ovaries for the best results. After around age 40, the ovaries' size decreases - an early sign that the number of follicles, and potential eggs, is depleted. Women with few eggs in their ovarian reserve are less likely to have an adequate ovarian response for successful IVF.

"The follicle count is just as good a test for ovarian response as expensive and time consuming endocrine tests," says Kwee, who adds that the count appears to be "the only test able to reliably predict low and high responders."

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
