Low-grade albeit longstanding inflammation may have a pivotal role in the ovary

Academicians from Japan led by Associate Professor Makoto Orisaka published their update related to the role of inflammation in polycystic ovaries, endometriosis, and aging in the medical journal Frontiers in Endocrionology. Inflammation is the response of tissues to noxious stimuli that may be acute, longstanding, i.e. chronic, and may have adverse outcomes on the body even though being a defensive action involving vessels and white blood cells. In this regard, chronic low-grade inflammation may have adverse effects on many ovarian reproductive…

The role of immunity in endometriosis

Academicians from Japan and China have recently published their comprehensive updated immunological review for endometriosis in the Journal of Reproductive Immunology.  Endometriosis is a multifactorial condition with multiple theories of pathogenesis. The role of innate and adaptive immunology in this regard has not been unveiled yet. However, scientific research related to immunity in endometriosis has been restricted to observational papers. Innate immunity seems to play an important role in the pelvic environmental milieu, especially in retrograde menstruation of endometrial cells. In unilateral…

Postmenopausal endometriosis is often neglected

Romanian academicians led by Dr. Mihai-Daniel Dinu have published their review of the published scientific data related to postmenopausal endometriosis in a recent special issue of the medical periodical Life. Even though endometriosis is accepted as a hormone-dependent disorder of reproductive years, endometriosis in postmenopausal patients may occur in a similar way to endometriosis in premenopausal patients. Some researchers have claimed the potential involvement of  the immune system in the development of endometriosis, Complaints of pelvic pain commonly underestimate the…

A comprehensive review of subdermal progestin in adenomyosis management

French academicians from Lyon and Marseilles led by Dr. Chene have published recently an electronic database search on the effectiveness of progestin subdermal implants in adenomyosis patients. This review appeared in the March 2024 issue of “The European Journal of Contraception & Reproductive Health Care” The long-acting reversible contraception progestin subdermal implant seems to be effective in ameliorating symptoms of endometriosis. Since adenomyosis is regarded as a histopathological form of endometriosis there is a question on the effectiveness of progestin subdermal…

The depth of the iceberg: Parametrial involvement in deep endometriosis

Academicians led by members of the International School of Surgical Anatomy from Italy have published their paper on parametrial involvement of deep endometriosis in the medical periodical named “Best Practice & Research Clinical Obstetrics & Gynecology”.  Deep endometriosis is troublesome when compared to the other endometriosis types due to the invasive properties beneath the peritoneum and also through the muscular layer of visceral organs. Few studies emphasize parametrial involvement is not a rare finding in patients with deep endometriosis who undergo surgery. This…

Ovarian endometriomas revisited

Dr. Farr R. Nezhat and his world-renowned team have published their narrative review on ovarian endometrioma in a recent issue of the Obstetrics and Gynecology. Endometriotic cysts (endometriomas) of the ovaries range from small (1–3 cm) to large (20 cm or greater) masses that affect 6% of patients with ovaries. Endometriomas have potential risks of chronic pain, infertility, pregnancy complications, and also cancer transformation. Two favored pathogenetic views for endometriomas are; endometriotic invasion or metaplasia of preexisting functional ovarian cysts and…

Sophisticated study yields hopes for a new potential remedy

Academicians from the Institute of Biomedical Sciences, Tokushima University Graduate School, Japan, conducted a clinical and experimental study on the role of SMAD (Suppressor of Mothers Against Decapentaplegic) molecules in endometriosis, and have published their results in a recent issue of Endocrine Journal. Activin is known to enhance the development of endometriotic lesions in laboratory mice. Also, a suppressor of mothers against decapentaplegic homolog 2/3 (pSAMA2/3) molecule in endometriotic lesions by immunostaining has been reported. Activin may therefore be involved in…

Stem cells may open new horizons in various gynecological disorders

In-Sun Hong, PhD, a researcher in regenerative medicine at Korean Gachon University has published a comprehensive review on the role of stem cells in gynecological disorders in a recent issue of the International Journal of Biological Sciences. Endometrium changes the menstrual cycle and the extraordinary regenerative capacity depends on tissue-resident stem cells within the uterine mucosa. Despite variations in specific characteristics among endometrial stem cells, the common denominator is strong self-renewal capacity and the ability to differentiate into multiple cell types. The…

Hot research in endometriosis; new vessel formation: angiogenesis

Caixia Bo and Yunfei Wang from Jining Medical University, China have recently published their comprehensive review on angiogenesis-related aspects of endometriotic tissues in a recent issue of journal named Molecular Medicine Reports. The main potential pathogenetic aspects of endometriosis include retrograde menstruation, uterine stem cells, and somatic epithelia. Whichever theory is operative, ectopic endometria needs nutrient support via new vessel formations, i.e., angiogenesis is the key factor for the viability of these ectopic islands. The authors have made literature search for…

Inguinal endometriosis is a commonly neglected differential diagnosis

A case series of inguinal endometriosis with eight patients from Tehran, Iran has appeared in a recent issue of the Journal of Medical Case Reports. It is a fact that many inguinal endometriosis cases are undiagnosed since they undergo herniorrhaphy by surgeons without any consideration for endometriosis. The estimated incidence of inguinal involvement is about 0.3–0.6% in all endometriosis cases and the total number of reported cases is 133 till 2022. This report presents eight Iranian cases of inguinal endometriosis…
