Clomiphene citrate with intrauterine insemination: is it effective therapy in women above the age of 35 years?

Agarwal SK et al., 1996 · Fertil Steril

To evaluate the influence of female age on clomiphene citrate (CC) with IUI therapy and to compare the efficacy of this therapy between patients with ovulatory and anovulatory infertility. A university fertility clinic. Six hundred sixty-four CC with IUI cycles from 290 women aged 22 to 48 years. Cumulative and clinical pregnancy rates (PRs). Both cumulative and clinical PRs declined substantially in women > 35 years when compared with those < or = 35 years. In addition, no difference in these parameters was noted between patients with ovulatory and anovulatory infertility diagnoses. The vast majority of pregnancies occurred within the first four treatment cycles, irrespective of age or ovulatory versus anovulatory infertility diagnoses. The age-related decline in clinical PR is most rapid beginning at the age of 35 years. For any given age group, CC with IUI therapy has similar cumulative and clinical PRs for both ovulatory and anovulatory infertility diagnoses. This therapy usually should not extend beyond four cycles. Couples should be counseled about the dramatic fall in PRs occurring beyond the age of 35 years.

Systematic review and meta-analysis of the etiology of heavy menstrual bleeding in 2,770 adolescent females

Hall EM et al., 2024 · BMC women's health · Free full text on PubMed Central

Adolescent heavy menstrual bleeding(HMB), menorrhagia or abnormal uterine bleeding commonly occur in adolescent women. The differential diagnosis can be challenging. The pneumonic: PALM-COEIN (polyp, adenomyosis, leiomyoma, malignancy and hyperplasia, coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, and not yet classified), is commonly used but it does not stratify as to the likelihood of a disorder. We have sought to develop a probability-based differential diagnosis for Adolescent HMB, menorrhagia or abnormal uterine bleeding. A comprehensive literature search was conducted using PubMed, EMBASE, and SCOPUS databases. Case series describing adolescents from 10-19 years of age with HMB, menorrhagia or abnormal uterine bleeding was acceptable if: more than 10 patients were included; editorials, case reports, and secondary sources such as review articles, or book chapters were excluded. No language filter was used, but an English abstract was required. The etiology of HMB, menorrhagia or abnormal uterine bleeding, and the country of origin was extracted from articles that met inclusion criteria. Cumulative rate estimates were determined by Bayesian probability modeling. Seventeen full text articles were reviewed in detail; 2,770 patients were included. The most frequent causes of HMB were Ovarian Uterine Disorders (23.7%; 95% CredI 22-25.5%), Coagulation Disorders (19.4%; 95% CredI 17.8-21.1%), and Platelet Disorders (6.23%; 95% CredI 5.27-7.27%) with 45.9% (95% CredI 43.8-47.%9) of the cases of indeterminate origin. The leading causes of HMB in healthy adolescent females were varied. The sub-analysis identified distinct etiologies, suggesting that multiple factors must be considered in the evaluation of HMB. While PALM-COEIN (polyp, adenomyosis, leiomyoma, malignancy and hyperplasia, coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, and not yet classified) provides us with a comprehensive picture of the possible causes of HMB in females, this systematic review assigns probabilities to the etiologies of HMB in adolescent females, providing physicians with a more focused and efficient pathway to diagnosis.

Uterine bleeding: how understanding endometrial physiology underpins menstrual health

Jain V et al., 2022 · Nature reviews. Endocrinology · Free full text on PubMed Central

Menstruation is a physiological process that is typically uncomplicated. However, up to one third of women globally will be affected by abnormal uterine bleeding (AUB) at some point in their reproductive years. Menstruation (that is, endometrial shedding) is a fine balance between proliferation, decidualization, inflammation, hypoxia, apoptosis, haemostasis, vasoconstriction and, finally, repair and regeneration. An imbalance in any one of these processes can lead to the abnormal endometrial phenotype of AUB. Poor menstrual health has a negative impact on a person's physical, mental, social, emotional and financial well-being. On a global scale, iron deficiency and iron deficiency anaemia are closely linked with AUB, and are often under-reported and under-recognized. The International Federation of Gynecology and Obstetrics have produced standardized terminology and a classification system for the causes of AUB. This standardization will facilitate future research endeavours, diagnosis and clinical management. In a field where no new medications have been developed for over 20 years, emerging technologies are paving the way for a deeper understanding of the biology of the endometrium in health and disease, as well as opening up novel diagnostic and management avenues.

Naprotechnology for Abnormal Bleeding and PCOS in Adolescents: Vital Sign-Based Evaluation

Gonzalez S, 2017 · Issues in Law & Medicine

The topic of how the menstrual cycle is a vital sign which could signal pathophysiologic process has received considerable attention in the past decade. The current recommendations of various academic groups will be discussed as well as the FertilityTMM Care method of charting and the Naprotechnology approach to evaluating abnormalities of the menstrual cycle. Two clinical scenarios seen in adolescent medicine, PCOS and AUB, will be analyzed looking at the pathophysiology of these clinical scenarios and their management. The approach will be one that conducts an evaluation to try to find the underlying problem and aims to restore the normal physiology of the menstrual cycle. The American Academy of Pediatrics, the American College of Obstetrics and Gynecology and the New York Academy of Sciences have published academic statements during the past ten years emphasizing the need for providers to teach patients how to chart and the important clinical ramifications of using this charting as a vital sign. In 2006 the American Academy of Pediatrics published in the Pediatrics Journal a recommendation titled: "Menstruation in Girls and Adolescents: Using the Menstrual Sign as a Vital Sign." In 2015, the American College of Obstetrics and Gynecology published a Committee Opinion emphasizing the need to teach women the charting of their menses and the important pathophysiologic process that could be detected with the charting.
