This study was carried out to explore associations between assisted reproductive technology (ART) and maternal and neonatal outcomes compared with similar outcomes following spontaneously conceived births. We conducted a retrospective cohort study of pregnancies conceived by ART (N = 2641) during 2006-2014 compared to naturally conceived pregnancies (N = 5282) after matching for maternal age and birth year. Pregnancy complications, perinatal complications and neonatal outcomes of enrolled subjects were investigated and analysed by multivariate logistic regression...

Seminal fluid is often viewed as simply a vehicle to carry sperm to fertilize the oocyte, but a more complex function in influencing female reproductive physiology is now evident. Remarkably, seminal fluid contains soluble and exosome-born signaling agents that interact with the female reproductive tract to prime the immune response, with consequences for fertility and pregnancy outcome. Experiments in rodent models demonstrate a key role for seminal fluid in enabling robust embryo implantation and optimal placental development...

Partial/complete hydatidiform mole with coexisting fetus is a rare condition. Optimal management is a challenge that remains a dilemma since these pregnancies are associated with maternal as well as fetal complications including hemorrhage, preeclampsia, thromboembolic disease, intra uterine demise and increased risk of persistent trophoblastic disease. Here we report 2 cases of partial mole with live fetus after ICSI and a case of complete mole with coexisting fetus after ICSI in a turner mosaic that resulted in a live birth...

This workshop had four main objectives: (A) Trying to look at the preeclampsia (PE) problem "from the Space Shuttle": why preeclampsia has emerged in humans (a specific human reproductive feature among 4300 mammal species)? (B) Epidemiology: there are major geographical differences concerning early onset PE and late onset PE throughout the world. (C) Vascular: The very promising use of pravastatin in the treatment of the vascular maternal syndrome (based on the metabolism of carbon monoxide (CO), the role of inositol phosphate glycans P-type (IPG-P), a major role in comprehending the insulin resistance phenotype in preeclampsia...

Cell-free fetal DNA has received significant attention for the purposes of prenatal genetic testing in the past decade. Fetal DNA testing is a new method and promising for many applications such as aneuploidy screening, prenatal diagnosis, prediction of preeclampsia and more. A 37-year-old primigravida, with a pregnancy conceived by intracytoplasmic sperm injection (ICSI), was offered non-invasive prenatal testing (NIPT) due to advanced maternal age. NIPT performed at 23 weeks' gestation reported a diagnosis of monosomy X...

A systematic review and meta-analysis were performed to evaluate whether women who conceive with donor sperm have an increased risk of preeclampsia compared with those who use their partner's sperm. Studies that compared women who were impregnated by donor and partner sperm were included. The main outcomes assessed were preeclampsia and gestational hypertension rates. Altogether, 10,898 women (2342 pregnancies by donor sperm versus 8556 by the partner's sperm) were included from seven observational studies...

Helicobacter pylori (H. pylori) infection could be associated with extra-digestive diseases. Here, we report the evidences concerning the decrease in reproductive potential occurring in individuals infected by H. pylori, especially by strains expressing CagA. This infection is more prevalent in individuals with fertility disorders. Infected women have anti-H. pylori antibodies in cervical mucus and follicular fluid that may decrease sperm motility and cross react immunologically with spermatozoa, conceivably hampering the oocyte/sperm fusion...

OBJECTIVE: We aimed to evaluate the association between infertility etiology in ICSI pregnancies and preeclampsia; besides, we aimed to discuss the effect of the paternal factor in the pathogenesis of preeclampsia. HYPOTHESIS: We hypothesized that preeclampsia is more common in ICSI pregnancies with male factor. It is known that maternal exposure to paternal sperm cells over a time period has a protective effect against preeclampsia. Male partners with azospermia have no sperm cells in their seminal fluid, whose female partners will not be able to develop some protective immunity against preeclampsia...

For many years, the innate immunity was of less interest than the adaptive immunity because it was perceived to have secondary importance in the functionality of the immune system. During the past decades, with the advancement of knowledge about innate immune system, interest in innate immunity has grown dramatically and thus its function has been extensively studied. Innate immunity plays fundamental roles in the initiation and induction of adaptive immune responses. It consists of several cells and receptors including natural killer (NK) cells, macrophages (MQs), dendritic cells (DCs) and pattern recognition receptors (PRRs)...

Since the delivery of the first baby conceived via in vitro fertilization (IVF) in 1978, IVF has become a standard procedure in sterility treatment. In Germany, 78,000 IVF/intracytoplasmic sperm injection (ICSI) cycles are performed annually with a delivery rate per embryo transfer of about 20 %. The cumulative delivery rate after three trials is more than 50 %. The main medical problems are the high rates of multiple pregnancies of more than 20 %, which carry an increased risk for mothers (preeclampsia) and children (preterm delivery, lung immaturity, brain problems)...

Partial hydatidiform mole with a normal fetus is extremely rare. A 30-year-old woman presented at 19 weeks gestation with clinical manifestations of severe preeclampsia. The fetus revealed a normal 46,XX karyotype and the placenta revealed triploid 69,XXX from paternal isodisomy. Microsatellite analysis revealed that the fetus and the triploid partial mole were derived from one sperm and one oocyte, followed by duplication of paternal chromosomes in only a trophectodermal cell. The maternal serum levels of angiogenic factors were extremely high compared with those reported in preeclampsia, suggesting an angiogenic imbalance may have caused preeclampsia-like symptoms before 20 weeks of gestation...
