Abstract Purpose of review This review discusses the endocrinological aspects of recurrent miscarriage based on the literature from January to January , elaborating on the advances in the field and their impact on diagnosis and management. Recent findings Endometrial luteal phase defect is associated with recurrent miscarriage. Fifty years have passed since the diagnostic criteria for dating the endometrial biopsy was established by Noyes et al. This has been the gold standard and last year its accuracy and clinical utility were critically analysed. A Cochrane review has shown a small but statistically significant difference in the live birth rate in the subgroup of women in which progestogen was used to prevent recurrent miscarriage. Endocannabinoids and fatty acid amide hydrolase have been found to have a potential role in signalling for implantation and maintenance of pregnancy.

It is asserted that examination of the endometrium during the secretory phase yields more information about the time of ovulation, degree of progestational change, and normality of the endometrium than any other test used in sterility studies. Attention to qualitative changes in 8 morphological factors is most useful in dating the endometrial biopsy. During the 1st week of luteal activity, attention should be focused on changes occurring in gland epithelium: During the 2nd week , stromal changes including edema , predecidual reaction, stromal mitosis, and leukocytic infiltration are the key criteria.
Tissue from the fundus of the uterus gives the most reliable information. These critera were used in sterility biopsies taken from normally menstruating women over a 3-year period. Absence of organic endometrial disease and availability of accurate menstrual history were the only selection criteria. To test the validity of the dating criteria, change in basal body temperature was used to correlate endometrial dating with ovulation rather than onset of menstruation. To determine whether biopsy caused early menstruation, the secretory phases of the 25 patients who had recorded temperatures in at least 2 cycles in addition to that in which the biopsy was taken were examined.
The secretory phase was definitely shorter in the biopsied than control cycle, suggesting that biopsy does accelerate the onset of flow. However, further analysis showed that biopsy does not interfere with length of flow or succeeding menstrual rhythm.

Per quanto riguarda la sua istogenesi si ritiene che il mesenchima del legamento alveolo-dentale sia il punto di partenza. In passato si pensava che la forte incidenza della carie nella gravida fosse dovuta a sottrazione di sali minerali, costituenti importanti di smalto e dentina, da parte del feto per il suo necessario sviluppo. In sede di applicazione, a dosi terapeutiche, non provoca fenomeni irritativi locali. I vasocostrittori possono indurre direttamente contrazioni uterine e ipossia fetale mediante vasocostrizione dei vasi placentari con efficacia dose-dipendente.
Nella specie umana, indagini condotte per esposizioni prolungate e ripetute superiore alle nove ore alla settimana hanno evidenziato un aumento di aborti spontanei tra le mogli di dentisti e un aumento di anomalie congenite e aborti nelle assistenti alla poltrona; non esiste, comunque, dimostrazione che singole esposizioni inferiori a 30 minuti si associno a rischio significativo.
Molto utile la presenza del ginecologo di fiducia, obbligatoria in caso di gravidanze a rischio. Due sono inoltre gli elementi da considerare:
The endocrinological basis of recurrent miscarriages
Our survey included natural cycles, cycles following ovarian stimulation for IVF and embryo transfer, and cycles with hormone replacement therapy for oocyte donation, reviewing 27 reports identified in a computerized literature research. The ultrasonographic prognostic indicators for implantation evaluated included peri-ovulatory endometrial thickness and pattern and Doppler measurements of uterine artery blood flow.
For various sonographic parameters, negative predictive value, positive predictive value, sensitivity and specificity were calculated, based on published data. Sonographic parameters had a high negative predictive value and sensitivity, but a limited positive predictive value and low specificity. Several confounding factors may influence the interpretation of reports, and the statistical evaluation sometimes lacks calculation of the positive and negative predictive values of the parameters examined.
To assess the ability of histological dating to discriminate between women of fertile and infertile couples. The utility of histological dating of endometrium in the evaluation of infertile couples is uncertain.
Two starcrossed lovers in search of a poopy diaper. Join us on our adventures through IVF, recurrent miscarriage, and finally Wednesday, September 23, Fruit cake and Endometrial Function Testing So I went in to see my RE yesterday and had an endometrial biopsy done so the tissue could be sent to the researcher at Yale who pioneered the Endometrial Function Test click the link to see him compare the endometrial lining to a fruit cake.
I’ve pictured my endometrial lining looking like a lot of things. But never quite like this: The biopsy hurt, but not too badly about the same as the coculture biopsy , and it was over in a minute or two. The idea of this latest test is to get a sense of my lining and whether it is a receptive place for a little embryo to grow. Apparently results will take a couple of weeks, so we’ll see what said researcher thinks soon.
I have to say, I’m not holding my breath.

Endometrial Ablation, Fibroids, and Tubal Reversal Tubal reversal and pregnancy are both possible after endometrial ablation. Readers who would like more information about the possibility of pregnancy after ablation should read our previous blog articles about pregnancy after ablation. This article shares the personal story of Shaunda and her husband Darren.
This sample is sent to the pathologist for endometrial dating. The result is correlated with the beginning of the next menstrual period that occurs within the next few days. The biopsy indicates if there is any progesterone deficiency that may be associated with a history of recurrent pregnancy losses or infertility.

Its function is to house the embryo, allowing its implantation and favoring the development of the placenta. This process requires a receptive endometrium capable of responding to the signals of the blastocyst, which is the stage of development of the embryo when it implants. Though there is no consensus as to the implantation period in humans, clinical studies suggest that this process takes place between days 20 and 24 of a normal ovulation cycle Wilcox at al.
The evolution of our knowledge about the human endometrium contrasts with the lack of progress in developing new diagnostic methods for the dating and study thereof. The endometrium is still evaluated today by means of histological studies based on in observations described over 50 years ago Noyes at al. In , Noyes et al. They were able to relate different histological patterns with particular moments of the menstrual cycle by correlating the histological changes with the basal body temperature.
These morphological criteria continue to be used today and are considered the Gold Standard for the study of the endometrium, evaluation of endometrial receptivity and detection of endometrial anomalies. However, this technique does have its drawbacks. It has been demonstrated that the use of histological features fails when distinguishing the phase of the menstrual cycle, and it also fails as a means to discriminate between fertile and infertile women, concluding that it is not suitable for clinical use.
The subjectivity involved in visual observation means that there is an inter-observer, intra-observer and inter-cycle variability altering the consistency of the results obtained. Furthermore, ovarian stimulation typical of assisted reproductive treatments ART modifies the endometrial maturation process compared to natural cycles which can barely be explained with Noyes’ criteria Papanikolaou et al.

Received Aug 5; Accepted Oct Summary The importance of performing an endometrial biopsy in women preparing for oocyte donation goes beyond confirming the histologic response to hormone replacement therapy. Additional information related to uterine architecture, ease of embryo transfer, status of the ovaries, and patient compliance is also gained.
Finally, the return visit provides an opportunity to discuss plans for the upcoming cycle.
