The effects of metformin and calcium-vitamin D in regulating the menstrual cycle suggest that they could also be effective for the treatment of anovulation and oligomenorrhea, with possible consequences for pregnancy rates in PCOS patients.
Background Different mechanisms have been described for the effects of acupuncture on fertility. Acupuncture may mediate neurotransmitter release, which results in the stimulation of gonadotrophin-releasing hormone secretion. The production of neurotransmitters such as endogenous opioids may also inhibit central nervous system outflow and biological stress response. Acupuncture may also stimulate blood flow to the uterus by inhibiting uterine central sympathetic nerve activity. Despite some evidence suggesting beneficial effects of acupuncture on in vitro fertilisation (IVF) success rates, recent clinical trials could not duplicate these effects, especially in patients who are infertile with polycystic ovarian syndrome (PCOS) who are undergoing IVF. Methods A total of 62 women with PCOS undergoing IVF/intracytoplasmic sperm injection (ICSI) at Shayamehr IVF Clinic in Tehran (Iran) participated in a randomised, controlled trial. Participants were randomly allocated to one of two groups: there were 31 women each in the acupuncture (group I) and control groups (group II). Acupuncture based on traditional Chinese medicine was performed in group I versus no adjunctive treatment in group II. All acupuncture procedures were performed in five sessions: start of downregulation, start of stimulation, 2 days before ovum pick-up, and immediately before and after embryo transfer. We measured the rate of oocytes in metaphase II, the fertilisation rate and the quality of embryos.Results Our results showed a statistically higher mean of good quality embryos in group I compared with group II ( p=0.044). However, the mean number of metaphase II oocytes retrieved
BackgroundCesarean section rates are increasing worldwide, and a rapid increase has been observed in Iran. Disagreement exists between clinicians about when to use cesarean section. We aimed to identify the appropriateness criteria for the use of cesarean section in Iran.MethodA consensus development study using a modified version of the RAND Appropriateness Method (RAM). We generated scenarios from valid clinical guidelines and expert opinions. A panel of experts participated in consensus development: first round via mail (12 members), second round face-to-face (9 members). We followed the RAM recommendations for the development of the scenario lists, rating scales, and statistical analyses.Results294 scenarios relevant to cesarean section were identified. 191 scenarios were considered appropriate, of which 125 scenarios were agreed upon. The panel found cesarean inappropriate for 21% of scenarios, and 'equivocal' for 14% of scenarios.ConclusionRAM is useful for identifying stakeholder views in settings with limited resources. The participants' views on appropriateness of certain indications differed with available evidence. A large number of scenarios without agreement may partly explain why it has been difficult to curb the growth in cesarean section rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
