Approximately 25% percent of women experience some sort of bleeding during their first trimester. There are several potential causes for bleeding during pregnancy, and many doctors believe some bleeding is normal. If you experience bleeding during pregnancy, it is best to inform your doctor right away to rule out major complications.
Research teams in Australia and Britain have discovered a gene mutation that impacts sperm motilityin mice.
Male mice with the RABL2 gene mutation demonstrated no outward signs of impaired fertility, though their sperm had 17 percent shorter tails than those without the mutation. This causes a problem for conception, as the sperm are not equipped to swim long enough to reach and fertilize the female egg.
Prolactin is the hormone responsible for milk production and has been dubbed a “natural birth control” for breastfeeding women. However, high levels of prolactin, or hyperprolactinemia, is undesirable in women trying to conceive. In both of these instances, prolactin inhibits ovulation.
The world’s largest multi-center fertility clinic, Equipo IVI, used the clinically certified EmbryoScope® Time-lapse System to culture and select embryos- a procedure that improved success rates up to 20 percent.
Legislation proposing infertility coverage for disabled veterans was approved by a Senate committee just last month. The bill offers coverage by the Department of Veterans Affairs for assisted reproductive technologies (ART), like in vitro fertilization (IVF) to veterans with combat-inflicted injuries that impact their ability to have children.
Reports from Japan say scientists have created eggs from mouse stem cells, then bred healthy offspring from these eggs.
Published this week in the journal Science, Professor Mitinori Saitou and his team at Kyoto University achieved this unprecedented goal which may open doors for human reproduction, though further research is warranted.
An article published by PLoS ONE suggests inhibiting the PTEN molecule, a cell-growth regulator, can cause immature eggs to mature.
Researchers led by Professor Kui Liu at the University of Gothenburg in Sweden have recently discovered that a chemical PTEN inhibitor can aid in healthy egg growth by shutting off the mechanism that naturally regulates cell growth.
Recent evidence suggests that freezing an embryo and thawing it for use in a woman’s next cycle, via in vitro fertilization (IVF), may result in higher pregnancy rates compared to a cycle using fresh embryos.
A recent study conducted by the Center for Human Reproduction (CHR) and published online by the journal PLoS ONE1, examined gene mutations increasing a woman’s risk for breast and ovarian cancers - with the added discovery of how human embryos with these mutations survive.
