In 323 stimulated cycles of women participating in in vitro fertilization treatment, a transvaginal Doppler examination was performed on the day of ovulation induction to investigate the value of blood flow velocimetry of the uterine artery. The results showed a significantly lower pulsatility index in patients who conceived (n = 42) compared with...
Article
Vaginal sonography is a well-established method to monitor follicular growth and to detect the optimum time for induction of ovulation with hCG. In this study we found significantly less and smaller follicles in the left ovary compared to the right. However, during the procedure of oocyte retrieval we found an equal number of follicles and oocytes...

Chapter
There have been pregnancies in several clinics after the replacement of frozenthawed cleaving embryos or expanded blastocysts (1–6). Embryo freezing allows replacement during cycles subsequent to the in vitro fertilization (IVF) cycle and avoids the pressure to replace large numbers of fresh embryos with the attendant risks of multiple pregnancy.
Chapter
In vitro fertilization (IVF) and embryo transfer (ET) not only give those patients with severely damaged tubes a real chance to become pregnant and to deliver their own children, but moreover, open up the possibility of becoming pregnant to women without ovaries. Provided a functional uterus is present, these women with absent or notfunctional ovar...
