Selected pathological conditions affecting endometrial receptivity
Understanding endometrial receptivity is key for successful embryo implantation. Factors like PCOS and endometriosis can disrupt this, but new research in reproductive immunology offers hope for improved assisted reproduction outcomes.
Area of Science:
- Reproductive medicine
- Gynecology
- Immunology
Background:
- Endometrial receptivity is crucial for embryo implantation, influenced by physiological remodeling and immune activity.
- Disruptions to endometrial receptivity can be caused by conditions such as myomas, endometriosis, polycystic ovary syndrome (PCOS), and infections, including SARS-CoV-2.
- The timing of embryo transfer is critical for successful implantation.
Purpose of the Study:
- To summarize current knowledge on embryo implantation, focusing on the role of endometrial quality.
- To review recent literature on endometrial receptivity, PCOS, endometriosis, and SARS-CoV-2.
Main Methods:
- Comprehensive literature review of publications from August 2022.
- Searches conducted in Web of Science, Scopus, and PubMed/Medline databases.
- Focus on keywords: "endometrial receptivity", "polycystic ovary syndrome", "endometriosis", "SARS-CoV-2".
Main Results:
- Endometrial receptivity depends on a balance of physiological and immune factors, modulated by the microbiome.
- Various conditions and infections can impair this balance, affecting implantation success.
- Diagnostic tools include ultrasound, hysteroscopy, and endometrial biopsy with histological, immunohistochemical, microbiome, or transcriptome analysis.
- Treatments involve hormonal support, metformin for PCOS, and advanced therapies like cell infusions or growth factors for recurrent implantation failure.
Conclusions:
- Advances in transcriptomics, proteomics, and reproductive immunology provide deeper insights into embryo implantation.
- This enhanced understanding heralds a new era in assisted reproduction technologies.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Secretory Phase
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
