Child-free women feel intense pressure to have kids — but rarely stress over it — New study uncovers effects of social pressure to have children on different groups of US women – Women who choose to be permanently childfree perceive more social pressures to become mothers than other women, but feel less distress about not having kids than women who are childless from infertility or other reasons, a new national study shows.
Higher risk of birth defects from assisted reproduction – Researchers identified the risk of major birth defects associated with different types of assisted reproductive technology. They have compared the risk of major birth defects for each of the reproductive therapies commonly available internationally, such as: IVF (in vitro fertilization), ICSI (intracytoplasmic sperm injection) and ovulation induction.
Gene variation linked to infertility in women, study finds — Altered gene involved in both faulty cholesterol regulation and pregnancy hormone production – A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins researchers suggests.
New technique could save cancer patients’ fertility — Researchers grow immature human egg cells to nearly mature egg in laboratory. – Researchers have successfully grown a woman’s immature egg cells, contained in a tiny sac called a follicle, to a healthy and nearly mature egg in the laboratory. When an egg is fully mature, it is ready to be fertilized.
A substantial number of European patients travel to other countries for fertility treatment — Who goes abroad for fertility treatment and why? – Many European patients are travelling to other countries for fertility treatment, revealed by researchers at the 25th annual conference of the European Society of Human Reproduction and Embryology.
High levels of cycling training damage triathletes’ sperm – Cycling training may have a major impact on sperm morphology, as researchers have proved this fact in triathletes who have high intensity cycling training during thrie career.
Worldwide report shows increase in assisted reproduction: 250,000 babies (approximately) born in 1 year – Assisted reproductive technology (ART) is responsible for an estimated 219,000 to 246,000 babies born each year worldwide according to an international study.
Identification of genetic variants affecting age at menopause could help improve fertility treatment – For the first time, scientists have been able to identify genetic factors that influence the age at which natural menopause occurs in women. Ms Lisette Stolk, a researcher from Erasmus MC, Rotterdam, The Netherlands, told the annual conference of the European Society of Human Genetics that a greater understanding of the factors influencing age at menopause might eventually help to improve the clinical treatment of infertile women.
2 studies: The first finds twins born after fertility treatment have a higher risk of problems. A second study study finds reassuring evidence on the outcome of children born after embryo freezing. – Twins born as a result of assisted reproductive technology (ART) are more likely to be admitted to neonatal intensive care and to be hospitalised in their first three years of life than spontaneously conceived twins, according to new research in Europe’s leading reproductive medicine journal Human Reproduction.
Researchers identify key proteins needed for ovulation – study reveals essential step in female reproductive process. – Researchers from the National Institutes of Health and other institutions have identified in mice two proteins essential for ovulation to take place.
