The Guardian view on granny orcas: nothing to do with humans | Editorial

Fascinating work is being done on the family life of killer whales. But like research into New Caledonian crows, it has nothing to do with the way we live our livesEvolutionary biologists from British universities havefound new evidence to support their theory that, despite their infertile state,post-menopausal killer whales play a beneficial role in the lives of their grandchildren. The scientists have a serious purpose: they want to find out why orcas go through the menopause, a characteristic shared only by pilot whales and humans. But their work produces delightful insights, starting with the reminder that even orcas, most familiar from blood-soaked natural history documentaries, are in fact family-loving creatures that live in caring extended kinship groups, in which the females usually outlive the males by at least 20 years. So far, so very interesting. The danger comes when others take their research and use it to promote their own view of what constitutes a well-ordered society.Evolutionary biologists have been studying orcas for more than a decade in the search for an evolutionary benefit to the menopause that would explain why it happens. They now conclude that in mammal species where family groups stay together (rather than young males or females being forced to leave), there is a benefit in the form of whatthey term late-life helping. This is not a new idea: it originated in the 1950s. Onemore recent study suggested that it was actually mothering, not gr...

Polycystic ovary syndrome (PCOS) is a reproductive, endocrine, and metabolic disorder affecting millions of women worldwide. Women with PCOS are often identified in adolescence or early adulthood with symptoms of oligomenorrhea or hirsutism or when presenting for infertility care. The health risks associated out of PCOS, however, go far beyond management of these common presenting symptoms or fertility treatment and likely extend past the reproductive years through and beyond menopause. International surveys suggest that most patients are dissatisfied with long-term counseling related to medical and psychologic issues.

AbstractMenopur® is a highly purified, urine-derived, human menopausal gonadotropin containing both follicle stimulating hormone (FSH) and luteinizing hormone (LH) activity. It is an effective option for controlled ovarian stimulation (COS) in assisted reproductive technology protocols and for ovulation induction (OI) in anovulatory infertility, and is associated with a different endocrine profile from that of recombinant (r) FSH in these settings (in terms of serum levels of FSH, androgens and/or estradiol). When used for COS in women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI), Men...

CONCLUSION: The compiled results indicate that despite the multifactorial etiology of sexual/reproductive dysfunction, nutritional factors may affect the sexual and reproductive health in both men and women. However, it is necessary further studies to clarify this association, and simultaneously improve the approach and treatment of patients with sexual and/or reproductive problems.

Abstract BACKGROUND: Letrozole is widely employed as ovulation induction agent in women with PCOS, but its use in mild stimulation (MS) protocols for IVF is limited. Aim of the present study was to evaluate the feasibility of a MS protocol with letrozole plus hMG in non-obese PCOS women undergoing IVF after a metformin pre-treatment. METHODS: We retrospectively evaluated the data of 125 non-obese PCOS undergoing MS with letrozole plus hMG, 150 IU as starting dose, (group 1, N = 80) compared to those undergoing a conventional IVF stimulation protocols (CS) (group 2, N = 45) pri...

Classic galactosemia is an inherited disorder of galactose metabolism caused by mutations in the galactose-1-phosphate uridyltransferase (GALT) gene. Even with early adoption of the recommended galactose-restricted diet, over 80% of affected females develop Premature Ovarian Insufficiency (POI). In a study by Cramer et al, female carriers were observed to demonstrate an increased likelihood of infertility and early menopause. Conversely, a Dutch study by Knauff et al. found no difference in ovarian reserve when comparing classic galactosemia carriers and controls.
