A new study aims to provide healthy couples who have a child affected by a developmental disorder with a personalized pre-conception risk evaluation, in order to determine the likelihood of a future child being affected by the same condition.
Sickle cell disease is a form of anemia that is inherited when both parents are carriers of a mutation in the hemoglobin gene. Currently, it can only be diagnosed in pregnancy by carrying out an invasive test that has a small risk of miscarriage and is therefore sometimes declined by parents. Now, researchers have developed a noninvasive prenatal test for the disease.
Phthalates are used by industry in plastic products. Their toxic effect on the endocrine system is worrying. Indeed, the exposure of male foetuses to phthalates can have devastating consequences for the fertility. However, researchers (UNIGE/HUG) show that phthalate susceptibility depends largely on the genetic heritage of each individual. These results raise the question of individual vulnerability and the possible transmission to future generations of epigenetic changes that should normally be erased during foetal development.
Scientists at The Graduate Center of The City University of New York and Brooklyn College have discovered seasonal changes in dopamine levels in the female plainfin midshipman fish's inner ear helps hearing sensitivity grow in the summer mating season, making her better able to hear the male's mating calls.
New research, published in the journal Scientific Reports, shows that women undergo a significant mental as well as physical change during the late stages of pregnancy.
The man is implicated in about half of all cases of infertility. Despite the known importance of genetic factors in the non-production of sperm, only about 25% of these cases can be explained currently. Now a study has uncovered new potential genetic causes, and this discovery will help to develop better diagnostic tests for male infertility.
Mutations in the gene that codes for SLIT2, a protein expressed in fetal cells in placentas and involved in directing the growth of the fetal nervous system, may contribute to premature births, possibly by activating the mother's immune system. Mika Rämet of the University of Oulu and colleagues report these findings in a new study published June 13 in PLOS Genetics.
A new study led by Boston University School of Public Health (BUSPH) researchers finds that there is no consistent association between consuming iron and becoming pregnant.
A new study has shown that popular magazines commonly feature older pregnant celebrities on their covers with no mention of the risks of advanced maternal age pregnancy or the advanced reproductive technologies and methods needed to achieve these pregnancies. By downplaying fertility decline with advancing age, these magazines likely contribute to women's belief that they can safely put off pregnancy until later ages.
A study examined girls' transitions through puberty in Madagascar and ways in which menstruation influences their educational experiences and future sexual and reproductive health. Findings revealed gaps in the girls' knowledge and an absence of support during puberty. Until this study little had been known about girls' experiences of puberty in Madagascar, which has among the highest rates of adolescent pregnancy compared with those in other parts of Africa.
