Researchers found that day 3 embryos biopsied for PGD implanted at the same rate as embryos from non-PGD cycles. Compared to routine IVF, their blastocyst survival rate after thawing = 87% versus 88% respectively. The implantation and clinical pregnancy rates were 35% versus 29% and 34% versus 36% respectively). The overall ongoing pregnancy rate for … Read More »
IVF is a very effective treatment that is often no more expensive than other treatments like COH/IUI when you consider the number of treatments necessary for each to reach a similar pregnancy rate. The following study comes to the same conclusion. Conclusion: One IVF treatment programme was more effective, but costlier than an intended course … Read More »
The study showed that the size of the embryo cohort does not affect the rate of normal embryos identified by PGD. The authors used array CGH to evaluate embryos on day 3 and day 5. The study was retrospective using data from a PGD reference lab. They studied 7753 embryos from 990 patients. Embryo Cohort Findings … Read More »
A study published on-line by the journal Obstetrics & Gynecology called “Effect of Hysterectomy With Ovarian Preservation on Ovarian Function” shows that menopause occurs about 2 years earlier in women with hysterectomy compared to women who did not have a hysterectomy. The study is important to infertility patients because one of the main theories regarding … Read More »

I have come to believe that one of the key factors that differentiates IVF outcomes is individualization and management of ovarian stimulation.
What is the best way to evaluate the uterine cavity for infertility and particularly before IVF? Take Home Lesson Hysteroscopy is more accurate than HSG for the uterine cavity HSG overall agreement with Hysteroscopy is 69% HSG false-negative rate is 78% HSG false-positive rate is 16% From this study, the answer is clearly hysteroscopy. Remember … Read More »
Japanese researchers explored a national database to determine whether thawed single-blast embryo transfer in natural cycles would reduce the risk of an ectopic pregnancy.
This study advances the authors long interest in the subject of fertility estimation after radiation therapy. Fertility preservation matters when we think about successful cancer treatment and more recently, for normal women who are not ready for pregnancy at an older maternal age. The authors use the best available mathematical models of oocyte depletion in … Read More »
