Many women do not follow the recommended guidelines to avoid contraception for 18-months after bariatric surgery.
A pregnant mother sleeping on her back during late pregnancy may cause problems for the fetus, according to new research published in the Journal of Physiology. This is the first study to monitor unborn babies overnight and at the same time record the mother's position during sleep.
Early pregnancy detection is vital in the cattle industry and improves animal welfare, whilst reducing consumer costs. A simpler, cheaper and safer early pregnancy test, has successfully advanced cattle farming over the last six years, with sales now exceeding $10 million per annum. The development of this test was borne from the discovery of a protein critical for pregnancy success, over 30 years ago.
Researchers in France and America find that aspects of facial contrast, a measure of how much facial features stand out in the face, decrease with age in women across a variety of ethnic groups. The researchers also find that observers perceive women with increased facial contrast as younger, regardless of the ethnic background of the women or the observers. This suggests that facial contrast is a cross-cultural cue to age perception.
Tests that estimate ovarian reserve, or the number of a woman's remaining eggs, before menopause, do not appear to predict short-term chances of conception, according to a National Institutes of Health-funded study of women with no history of infertility. The study appears in the Journal of the American Medical Association.
When it comes to birth control, many males turn to two options: condoms or vasectomies. While the two choices are effective, both methods merely focus on blocking the transportation of sperm.
Among women of older reproductive age attempting to conceive naturally, biomarkers indicating diminished ovarian reserve compared with normal ovarian reserve were not associated with reduced fertility, according to a study published by JAMA.
The scientific reasons why people live beyond the age of 50 are more complex than thought, according to a new genetic study.
New research from scientists at Huntsman Cancer Institute (HCI) at the University of Utah and collaborators at University of Utah Health (U of U Health) sheds light on the complex process that occurs in the development of human sperm stem cells.
A new Oxford University study has shed light on some of the reasons why Assisted Reproductive Technologies (ART) usage varies across Europe -- pinpointing moral and social acceptance of the treatment and religion as key. In new research published in Human Reproduction, scientists from the Oxford University Department of Sociology and Nuffield College, have for the first time assessed the relative importance of the role that economic, demographic and cultural normative factors play in the process.
