Sperm Sorting Device Developed At WPI May Improve Fertility Treatments

WORCESTER (CBS) – About 15-percent of couples experience infertility in the U.S. and at least a third of cases are due to male reproductive issues. But some local researchers have developed a sperm sorting device which may help couples trying to conceive improve their chances. When couples undergo fertility treatments such as in vitro fertilization (IVF), embryologists try to select the best sperm to use. That often involves a spinning process much like clothes in a washing machine, but those high forces can cause damage to the sperm and the DNA inside. “The less we subject the cells to outside forces, outside effects, the healthier that we have a chance of isolating the healthy ones,” says Erkan Tuzel, PhD, an associate professor of physics at Worcester Polytechnic Institute (WPI). Tuzel’s team and colleagues at Stanford University have created a device called SPARTAN (Simple Periodic ARray for Trapping And IsolatioN). It’s the size of a credit card and can sort out the healthiest sperm in a simple, gentle, and efficient way. Resembling an obstacle course, the device is made up of a series of 3-dimensional columns for sperm to swim around. Only the healthiest make it to the end the fastest.

This is a case series reporting live births following in vitro fertilization (IVF) after fertility-sparing surgery in patients with borderline ovarian tumors (BOTs). Seventeen patients, in whom fertility-sparing surgery for BOTs followed by IVF was performed from July 1, 2011 to September 30, 2017, in our IVF center, were included. Here we retrospectively present their BOT characteristics and clinical outcomes of assisted reproduction technology (ART) and then discuss the literature on management of patients with BOTs after fertility-sparing surgery. The study sample of 17 patients started IVF-assisted reproduction within ...

Introduction: Endometriosis is an enigmatic disease affecting up to 10% of reproductive-aged women causing pain and infertility. Deep infiltrating endometriosis (DIE) is the most severe form of the disease. The impact of surgical treatment for deep endometriosis on fertility success rate of assisted reproduction techniques (ART) is not clear.

Introduction: Since 2000, the Donor Sibling Registry (DSR) has connected more than 15,500 donor offspring with half-siblings and their biological parents. Accordingly, they have been able to create and explore these new familial relationships and can also understand their ancestry and learn about their medical backgrounds. 56,000 gamete donors, offspring, and recipients in 105 countries have registered on the DSR, seeking to find those with whom they share genetic ties.

Introduction: Submucosal fibroids result in abnormal uterine bleeding and infertility leading to hysteroscopic resections. The data on whether submucous fibroids should be removed is conflicting. The Cochrane dated February 2015 suggests that there is not enough evidence to recommend routing hysteroscopic resection of submucous fibroids. The AAGL (American Association of Gynecologic Laparoscopists) recommends the removal of submucous fibroids in infertility and in selected patients with abnormal uterine bleeding and recurrent pregnancy loss.
