Study Objectives: To understand gender differences in sleep quality, architecture and duration of young healthy couples in comparison to older couples in their natural sleep environment. Design: Sleep was monitored in a naturalistic setting using a headband sleep monitoring device over a period of two weeks for young couples and home polysomnography for the older couples. Participants: Ten hete...

Cells and tissues must maintain a reducing environment to survive. This reducing environment provides the electrochemical gradient needed for electron flow. This movement of electrons provides the energy needed to build and maintain cellular structures and associated functions. An array of redox couples is responsible for the electron transfer. Some of these redox couples are linked to each oth...

BACKGROUND The purpose of this investigation is to determine the efficacy of emotionally focused couples therapy (EFT-C) on enhancement of marital adjustment in infertile couples. MATERIALS AND METHODS This was a semi-experimental study with a pre- and post-test design. We selected 30 infertile couples (60 subjects) by purposive sampling. Couples were randomly assigned to two groups, sample a...

Recently, infertility treatment-related psychological effects are receiving increased attention. However, whether sexual satisfaction is reduced amongst infertile couples remains to be elucidated. In this study, sexual satisfaction of Japanese infertile couples was assessed using a validated questionnaire designed to assess the male and female partner individually, and the couple as a whole for...

OBJECTIVE To determine the usefulness of and cost-effectiveness of antisperm antibody testing in the prediction of poor fertilization rates in couples undergoing IVF. DESIGN Retrospective cohort study. SETTING A hospital-based reproductive endocrinology and infertility practice. PATIENT(S) Male partners of 251 couples undergoing IVF between 1992 and 1997. MAIN OUTCOME MEASURE(S) Fertili...

Fertility Differences between Married and Cohabiting Couples: A Switching Regression Analysis Little is known about why cohabiting couples have fewer children than married couples. We explore the factors that explain the difference in fertility between these two groups using a switching regression analysis, which enables us to quantify the contribution of different factors through a decompositi...

We describe a distress prevention training program for couples and three empirical studies that support its effectiveness. The program, Couples Coping Enhancement Training (CCET), is based both upon stress and coping theory and research on couples. In addition to traditional elements of couples programs (e.g., communication and problem-solving skills), the CCET also addresses individual and dya...

We have used four oligonucleotide probes and two restriction enzymes to detect the beta thalassaemia mutation in a group of 61 couples of Italian descent who were prospective parents. We have been able to define the beta thalassaemia mutation in both parents in 47 couples and in only one parent in 12 couples. Prenatal diagnosis was accomplished successfully either by amniocyte (two) or trophobl...

This study investigated intimate partner violence in interracial and monoracial relationships. Using a nationally representative sample, regression analyses indicated that interracial couples demonstrated a higher level of mutual IPV than monoracial white couples but a level similar to monoracial black couples. There were significant gender differences in IPV, with women reporting lower levels ...
