As we reported in our blog earlier this year, fertility specialists in Sweden transplanted uteri into women who were unable to carry a pregnancy to help them. They were presumably motivated by one of the remaining challenges in Reproductive Medicine, helping women who were born without a uterus, or have had their uterus removed or have severe scar tissue in the uterus making it difficult or impossible to carry a pregnancy. The only options for these couples until now has been to use a gestational carrier with IVF to carry the pregnancy for them, what most people think of as a “surrogate.” Picking up on research that began over a century ago, doctors in Sweden used modern surgical techniques and medications to enable transplantation of the uterus. There is now some good news on this front. One of these transplants in Sweden resulted in a healthy live birth. The pregnancy and birth were not without complications. The baby was born 9 weeks early and the mom developed pre-eclampsia, a serious condition in pregnancy also known “toxemia” whose symptoms include high blood pressure and swelling. The doctors are also unsure if the uterus will be usable for a second pregnancy. Still, this an exciting first in Reproductive Medicine.
There are plenty of reasons to quit smoking. The health effects of smoking are well known and well documented, not just on your fertility, but a whole number of health issues including heart disease and cancer. Now, there’s yet another reason to quit smoking if you are pregnant or trying to get pregnant. Cigarettes may actually affect a woman’s male offspring’s sperm quality. As reported in Human Reproduction, the male offspring of pregnant mice exposed to high levels of cigarette smoke had sperm with lower counts, lower motility and more abnormally shaped sperm (low morphology), and these male mice took longer longer to impregnate female mice who in turn gave birth to fewer mouse pups. So, what does this all mean? While we don’t yet know if this is true in humans (or even 100 % sure it is true in animals), exposure to tobacco smoke could not only harm your fertility (among other things) but also could harm your unborn son’s chances of fathering children. This is another good reason to quit.
In recent years, Vitamin D has become the all the rage in medical research. It seems everybody these days is deficient in Vitamin D and a whole range of medical conditions from cancer to osteoporosis to reproductive issues have been potentially linked to insufficient Vitamin D. A recent study, which was in agreement several other previous studies, showed that women doing IVF with higher Vitamin D levels actually had significantly higher pregnancy rates than those who did not. While it is not clear at this time whether Vitamin D deficiency actually causes infertility or even whether supplementation will help couples conceive, it does suggest that maintaining healthy Vitamin D levels may contribute to good reproductive health.
Polycystic ovarian syndrome (PCOS) is one of the most common things doctors see in both reproductive medicine and OBGYN practices. Patients often come to us complaining of infertility, miscarriages or irregular cycles, and sometime other issues such as facial hair, acne or weight issues. Because of these are the problems that bring PCOS patients in the office, most patients (and most doctors as well) think of it as a gynecologic disorder. However, most experts consider most PCOS to be a metabolic disorder, a problem with how the body handles sugar and produces insulin, and that the symptoms of PCOS are the consequences of these metabolic problems. A recent article from the Wall Street Journal, discusses PCOS and interviews some of the leading researchers in the field.
