The potential effects of enflurane, isoflurane, halothane, fluroxene and nitrous oxide on mortality and fertility in Drosophila melanogaster were examined. The LD50 value 1 day after exposure for 1 h was the same for males and females and was about 8% for enflurane, isoflurane and halothane, about 20% for fluroxene, and greater than 100% for nitrous oxide. Male and female fertility, however, we...

CONTEXT Whether infertile women exhibit accelerated ovarian aging and whether a low ovarian reserve is overrepresented in infertility populations is not known. OBJECTIVE To compare the age-related decline in antral follicle count (AFC), a biomarker of the ovarian reserve, in fertile and infertile women. DESIGN Cross-sectional data from a large prospective cohort study conducted from January...

The daily challenge of getting cows pregnant is nothing new to any dairy producer. What is new is the variety of approaches that researchers are taking to understand the mechanisms underlying this problem and propose effective solutions to it. Our applied reproductive research program is focused on controlling ovarian physiology to optimize fertility of lactating dairy cows. Our goal is to deve...

There are relatively few effective clinical options for preserving female fertility, particularly following aggressive chemotherapy and/or radiotherapy treatment protocols. This document reviews the scientific background, current technology, clinical results and potential future applications of two methods for preserving female fertility—ovarian tissue cryopreservation and oocyte cryopreservati...

In the last decade, fertility preservation has risen as a major field of interest, creating new interactions between oncologists and gynecologists. Various options, such as cryopreservation of ovarian tissue, have been developed and are currently routinely proposed in many centers. However, many of the options remain experimental and should be offered to patients only after adequate counseling....

Background: Electromagnetic fields interact with human tissues and may have adverse effects on fertility and reproduction. During the last decades there has been a growing concern on the effects of electromagnetic radiations on biological systems in general. Radiation risks from electromagnetic fields generated by processes such as reduced fertility and a significant decrease in implantation ra...

BACKGROUND Obesity is rapidly becoming a worldwide epidemic that affects children and adults. Some studies have shown a relationship between obesity and infertility, but until now it remains controversial. Thus, the aim of the present study was to investigate the effect of high-fat diet-induced obesity on male reproductive parameters. METHODS In a first experiment, male Wistar rats were fed a...
