Pioneering research presented at the Fertility 2013 conference today (Thursday 3 January 2013) shows that a large proportion of male cancer patients are missing out on appropriate fertility advice. Sperm banking is routinely recommended for all men diagnosed with cancer who are at risk of long-term infertility, caused by treatment such as chemotherapy and radiotherapy. Infertility can be permanent or temporary depending on the individual's circumstances and men may need to attend...

New Gene Discovery Could Lead To Non-Hormonal Contraceptive For Men

Male contraception may be a possibility thanks in part to a discovery of a new key reproductive gene critical for production of healthy sperm, suggests Scottish scientists credited with the discovery. Researchers from Edinburgh University are hopeful their study, which involved mice, could lead to a new type of male birth control that doesn´t disrupt the production of hormones, something which often causes side effects such as mood swings. The researchers found that a gene known as...

(Ivanhoe Newswire) - A new type of male contraceptive could be created thanks to the discovery of a key gene essential for sperm development. This could lead to alternatives to the conventional male contraceptives which rely on the production of hormones, such as testerone. Research led by the University of Edinburgh, shows how the gene Katnal1 is critical to enable sperm maturity in the testes. If scientists can regulate Katnal1 in the testes, they could prevent sperm completely maturing,...

A new study published in the International Journal of Andrology reveals that semen quality has significantly deteriorated during the last ten years in Finland, a country that previously was a region with high sperm counts. At the same time, the incidence of testis cancer in the Finnish population showed a remarkable increase, following the worrying trends observed in several countries in Europe and the Americas. Led by Jorma Toppari, MD, PhD, of the University of Turku, researchers examined...

Researchers have now found a way to propagate primary human Sertoli cells in the laboratory -- the first step, say investigators, to developing an artificial human testicle for reproductive research. Derived from the testis, it has been difficult to maintain Sertoli cells, the "nurse" cells responsible for overseeing sperm production, outside of the human body. San Francisco, CA (Vocus) October 25, 2010 After more than 30 years of unsuccessful efforts by numerous investigators,...

One in seven couples worldwide has difficulty conceiving a child, and male infertility is thought to account for nearly half of those cases. Although the cause of male infertility is often unknown, scientists have now discovered a genetic alteration that disrupts sperm production in otherwise healthy men. The research, published by Cell Press on September 30th in the American Journal of Human Genetics, provides new insight into one cause of male infertility. "Many genes are known to be...

Office-based, surgeon-performed, ultrasound-guided, fine needle aspiration (FNA) of head and neck lesions yields a statistically significant higher diagnostic rate compared to the standard palpation technique, indicates new research in the March 2010 issue of Otolaryngology "“ Head and Neck Surgery. FNA is a diagnostic procedure used to investigate superficial lumps or masses. In this technique, a thin, hollow needle is inserted into a mass to extract cells for examination. FNA biopsies...

And also compared to pregnancies achieved after non-IVF fertility treatment Women who become pregnant with a single fetus after in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) have an increased risk of a stillbirth, according to new research out today (Wednesday). The study of over 20,000 singleton pregnancies, published in Europe's leading reproductive medicine journal Human Reproduction [1], found a four-fold increased risk of stillbirths for women who had IVF/ICSI...

It has been thought that men with non-obstructive azoospermia (NOA), a lack of sperm in the semen not caused by an obstruction within the reproductive system, are poor candidates for IVF. Now, researchers writing in the open access journal Reproductive Biology and Endocrinology have shown that sperm from men with NOA and obstructive azoospermia (OA) are equally capable of producing embryos. Nina Desai led a team of researchers from the Cleveland Clinic Foundation who carried out an in-depth...

British scientists say they have created human sperm in a laboratory, which they said could help men with fertility problems father a child. Other experts, however, say they aren't convinced the team of scientists from Newcastle University and the NorthEast England Stem Cell Institute created fully developed sperm, the BBC reported Wednesday. Within 10 years, the team said, its technique could be used to allow infertile couples to have children, The Daily Telegraph reported. It could be...
