Ectopic pregnancies with unusual location and an angular pregnancy: Report of eight cases.

Objective: The increased use of assisted reproduction techniques has been accompanied by an increase in ectopic pregnancies with unusual location being associated with significant maternal morbidity and mortality. This article reports on seven cases of ectopic pregnancies with unusual location and an angular pregnancy. Diagnostic and therapeutic strategies are discussed and a brief review of literature is presented.

Age-related distribution of basal serum AMH level in women of reproductive age and a presumably healthy cohort.

In this study, day 1 to 4 serum anti-Müllerian hormone (AMH) level was analyzed in 2,741 patients attending our department for reproductive medicine or reproductive surgery, including a subgroup of 1,105 women who attended an assisted reproductive technology program because of a male factor as a presumably healthy subgroup. Day 1 to 4 serum AMH levels showed an age-dependent distribution and there is a wide range of AMH in each year of age analyzed, showing that even young women are at a risk of reduced ovarian reserve.

Anti muellerian hormone serum levels in women with endometriosis: a case-control study.

Objective: To compare the anti muellerian hormone (AMH) serum levels in women with and without endometriosis.

Design: A case-control study

Setting: Women's General Hospital, Linz, Austria.

Patient(s): Our study included a total of 909 patients undergoing in vitro fertilisation/intracytoplasmic sperm injection (IVF/ICSI) treatment or consulting our specific endometriosis unit.

Cryopreserved blastocysts have a lower implantation but an equal live birth rate as compared to fresh blastocysts of the same quality - a case-control study.

The purpose of this case-control study was to compare implantation, pregnancy, and live birth rate of cryopreserved embryos with that of fresh embryos. A total of 1,488 assisted reproductive technology (ART) trials including 188 cryopreserved embryo replacement trials were reviewed. After proofing the exclusion criteria, 112 patients undergoing a cryopreserved embryo replacement (study group) were matched with 112 patients undergoing a fresh embryo transfer (control group).

Risk in twin pregnancies after the use of assisted reproductive techniques.

Objective: To analyze whether there is an increased perinatal risk for twin pregnancies after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).

Study Design: The medical files of 216 twin pregnancies (group 1) conceived through IVF/ICSI and 377 spontaneously conceived twin pregnancies (group 2) were assessed retrospectively. Data on gestational age at delivery, mode of delivery, birth weight, neonatal intensive care unit admission, duration of hospitalization, perinatal mortality and malformations were recorded.

Birth weight is lower for survivors of the vanishing twin syndrome: a case-control study.

Objective: To compare the outcome of singleton pregnancies originating from a twin gestation with singleton pregnancies originating from a single gestation.

Design: Case-control study.

Setting: Women's general hospital in Austria.

Cytoplasmic pitting has a negative influence on implantation outcome.

Purpose: Since cytoplasmic pitting is a morphological phenomenon discussed controversially, this study was set up in order to assess the actual influence of cytoplasmic pitting on treatment outcome.

Methods: Four hundred and one patients undergoing 484 consecutive treatment cycles were evaluated retrospectively in order to assess the actual influence of pitting on treatment outcome.

Results: Pitting was found to be reduced in single culture as compared to group culture (p < 0.

Occurrence and developmental consequences of vacuoles throughout preimplantation development.

Objective: Since little is known about the actual incidence and fate of vacuoles at different stages of development this preliminary study was set up to accurately measure vacuoles and track them to day 5.

Design: Prospective study.

Setting: Women's General Hospital in Austria.

Premature rupture of membranes with oligo- or anhydramnios before 24 weeks of gestation and the chances of fetal survival.

Unlabelled: Rupture of the membranes before the fetus has achieved viability within the womb is an event of enormous importance for both mother and physician. The potential outcome ranges from fetal death, a frequent occurrence, to a severely disabled life or a happy (but rare) birth without any mental or physical retardation for the child. The aim of the present investigation was to provide the consulting physician with valid data, enabling him/her to make a realistic assessment of the risks and to inform the patient accordingly.

Assisted vaginal delivery versus caesarean section in breech presentation.

Background: The Term Breech Trial (TBT), a well-known study conducted by Hannah and published in the Lancet, revealed a better outcome for neonates after primary caesarean section compared with attempted vaginal delivery. The aim of the present study was to determine whether the results of TBT have to be taken into account when counseling pregnant women in central Europe.

Methods: We investigated 882 women who had delivered infants in breech presentation over a period of 11 years.

The potential of preoperative beta-hCG and progesterone levels to predict failure of laparoscopic linear salpingostomy in ectopic pregnancies.

Study Objective: To estimate the association between preoperative beta-human chorionic gonadotropin (hCG) and progesterone levels, and success of linear salpingostomy in treatment of tubal pregnancy.

Design: Retrospective case control study (Canadian Task Force classification II-1).

Setting: Women's general hospital.

Successful birth after laser assisted immobilization of spermatozoa before intracytoplasmic injection.

Objective: To describe the first ICSI pregnancy achieved with sperm that were immobilized by using a noncontact diode laser.

Design: Case report.

Setting: Fertility center.
