Introduction: The exposure of endometrium to supraphysiological steroid levels
during the follicular phase of an IVF cycle results in histological abnormalities
and subsequently affects pregnancy rates. It has been demonstrated that
prolonged duration of stimulation after the end of menstruation and until the
day of hCG administration (menstruation-free interval) is associated with a decreased
probability of ongoing ...

OBJECTIVE: To investigate the association between the probability of pregnancy and hormone exposure between the end of menstruation and the day of triggering final oocyte maturation (menstruation-free interval). DESIGN: Prospective study. SETTING: University. PATIENT(S): One hundred women (aged ? 39 years) stimulated with a fixed dose of recombinant follicle-stimulating hormone (200 IU). INTERVENTION(S): Daily gonadotropin-releasing hormone ...

How to define and promote a healthy state of the vaginal microbiome is not well understood. Knowledge of which underlying factors shape the microbial community composition of the vagina and how to modulate them will contribute to vaginal disease prevention and improve fertility. A healthy state of the vaginal microbiome can prevent vaginal disease and promote successful fertilization and healthy pregnancies. Little is known about the stability ...

CONTEXT: Heavy menstrual bleeding (HMB) is common and debilitating, but the precise endometrial mechanisms causing increased menstrual blood loss (MBL) remain undefined. We have previously identified a role for hypoxia in endometrial repair following progesterone withdrawal. OBJECTIVE: As hypoxia inducible factor 2 alpha (HIF2A) is known to alter vascular function in other tissues, we hypothesised that endometrial HIF2A is involved in ...

Journalists, non-profits and consumer organisations, as well as the authors’ first-hand review of relevant privacy policies reveal that fertility and menstruation tracking apps (FMTs) collect and share an excessive array of data. Through doctrinal legal research, we evaluate this data processing in light of data and consumer protection law but find the commonly invoked concepts of ‘vulnerability’, ‘consent’ and ‘transparency’ insufficient to ...

Women with a history of bariatric surgery are recommended to avoid pregnancy at least 12 months after surgery. Evidence on the impact of bariatric surgery on contraception, menstrual cycle, and sexuality in the first year postoperative is therefore indispensable.

By means of a questionnaire the complaints women have in the days before the menstruation were assessed in 97 female singers and 204 female non-singers: general premenstrual symptoms, complaints of the speaking voice and the singing voice. A vast majority of all our respondents had general premenstrual complaints. One third of the non-singers had speaking voice complaints, whereas more than half of the singers had. Most mentioned complaints of ...
