Mullerian Anomaly

Mullerian anomalies are developmental malformations of the female reproductive tract, often diagnosed late. They are classified into numerous types like a septate uterus, bicornuate or unicornuate uterus etc. A rudimentary non-communicating functional horn is a rare variant of a unicornuate uterus. It may present with a wide spectrum of symptoms like severe dysmenorrhea, infertility, lump in abdomen or rarely maybe diagnosed with a ruptured ectopic in the horn. The diagnosis of this entity is a difficult and challenging. Authors present a case of a young adolescent diagnosed with this Mullerian anomaly, the role of hysteroscopy in confirmation of diagnosis and the management of the patient by laparoscopy successfully. The patient was completely relieved of her symptoms post-surgery.

Aryl Hydrocarbon

The dioxin/aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor responsive to both natural and man-made environmental compounds. AhR and its nuclear partner ARNT are expressed in the female reproductive tract in a variety of species and several indications suggest that the AhR might play a pivotal role in the physiology of reproduction. Furthermore, it appears to be the mediator of most, if not all, the adverse effects on reproduction of a group of highly potent environmental pollutants collectively called aryl hydrocarbons (AHs), including the highly toxic compound 2,3,7,8-tetrachlor-odibenzo-p-dioxin (TCDD). Although a large body of recent literature has implicated AhR in multiple signal transduction pathways, the mechanisms of action resulting in a wide spectrum of effects on female reproduction are largely unknown. Here we summarize the major types of molecular cross-talks that have been identified for the AhR and linked cell signaling pathways and that are relevant for the understanding of the role of this transcription factor in female reproduction.

Abstract Background Robert’s uterus is a rare Mullerian anomaly, which can be described as an asymmetric, septate uterus with a non-communicating hemicavity. Herein, we present the case of a misdiagnosed Robert’s uterus, resulting in an invasive and disadvantageous surgery. Case presentation A 16-year-old woman was referred to our department because of dysmenorrhea and suspicion of uterine malformation. We misdiagnosed Robert’s uterus as a unicornuate uterus with a non-communicating rudimentary horn and hematometra, and performed laparoscopic hemi-hysterectomy. Although the patient’s symptoms were relieved, our surgical procedure left the lateral uterine wall weak, making the patient’s uterus susceptible to uterine rupture in any future pregnancy. Conclusions Although the early diagnosis of Robert’s uterus is challenging, it is important in order to determine appropriate surgical interventions and management for maintaining the quality of life and ensuring safety in future pregnancies.

While vitamin D insufficiency is known to impact a multitude of health outcomes, including HIV-1, little is known about the role of vitamin D-mediated immune regulation in the female reproductive tract (FRT). We performed a pilot clinical study of 20 women with circulating 25(OH)D levels <62.5 nmol/L. Participants were randomized into either weekly or daily high-dose oral vitamin D supplementation groups. In addition to serum vitamin D levels, genital mucosal endpoints, including soluble mediators, immune cell populations, gene expression, and ex vivo HIV-1 infection, were assessed. While systemic vitamin D levels showed a significant increase following supplementation, these changes translated into modest effects on the cervicovaginal factors studied. Paradoxically, post-supplementation vitamin D levels were decreased in cervicovaginal fluids. Given the strong correlation between vitamin D status and HIV-1 infection and the widespread nature of vitamin D deficiency, further understanding of the role of vitamin D immunoregulation in the female reproductive tract is important.

AbstractIn polyandrous insects, postcopulatory sexual selection is a pervasive evolutionary force favouring male and female traits that allow control of offspring paternity. Males may influence paternity through adaptations for sperm competition, and females through adaptations facilitating cryptic female choice. Yet, the mechanisms are often complex, involving behaviour, physiology or morphology, and they are difficult to identify. In red flour beetles (Tribolium castaneum), paternity varies widely, and evidence suggests that both male and female traits influence the outcome of sperm competition. To test the role of spermathecal morphology and of sperm storage processes on the outcome of sperm competition, we mated each of 26 virgin females with two males, one of which carrying a phenotypic marker to assign offspring paternity. We manipulated the interval between mating with the first and the second male, to create different conditions of sperm storage (overlapping and non-overlapping) in the female reproductive tract. To investigate the role of sperm storage more closely, we examined the relationship between paternity and spermathecal morphology in a subset of 14 experimental females. In addition, we also characterized variation in spermathecal morphology in three different strains, wildtype, Chicago black and Reindeer. No significant influence of the intermating interval was found on the paternity of the focal male, although the direction of the difference was in the expected direction of higher last male paternity for longer intervals. Moreover, paternity was not significantly associated with spermathecal morphology, although spermathecal volume, complexity, and tubule width varied significantly and substantially among individuals in all investigated strains.

Angiogenic Effect

Antimicrobial peptides (AMP) are cationic peptides of innate immune system with antiviral, antibacterial and antiprotozoal activity. AMP act as immunomodulators, promote bacterial opsonization, inhibit proteases activity, have anti-endotoxic and angiogenic effect. The review describes main types of AMPs, features of their expression in female reproductive tract depending from menstrual cycle and during pregnancy. Data about the role of AMPs in defending from sexually transmitted infections (HIV, genital herpes, HPV, gonorrhea), in pathogenesis of extrauterine pregnancy and preterm birth are described. Possibility of practical application of AMPs as alternative to antibiotics and as contraceptives is estimated.

Endometrial cancer (EC) is a hormone-dependent cancer that currently represents the most frequent malignancy of the female reproductive tract. The involvement of steroid hormones in EC etiology and progression has been reported. More recently, gonadotropins, and, in particular LH/hCG, are emerging as novel regulators of tumor progression. In the present review, we discuss the role of the LH/hCG axis (i.e. LH/hCG and its receptors, LH/hCG-R) in both gonadal and nongonadal tissues, in physiological and neoplastic conditions. In cancer cells, LH/hCG mainly controls cell proliferation and apoptosis. In particular, in EC LH/hCG improves cell invasiveness, through a mechanism which involves the LH/hCG-R, which in turn activate protein kinase A and modulate integrin adhesion receptors. Indeed, the LH/hCG-R mRNA is expressed in primary ECs and this expression correlates with LH/hCG-induced cell invasiveness in vitro. These results lead to hypothesize that recurrent and metastatic ECs, which express LH/hCG-R, could benefit from therapies aimed at decreasing LH levels, through Gn-RH analogues. Hence, the LH/hCG axis could represent a prognostic factor and a new therapeutic target in EC.

And Function

Proper development and function of the female reproductive tract are essential for successful reproduction. Regulation of the differentiated functions of the organs that make up the female reproductive tract is well established to occur at multiple levels including transcription, translation, and posttranslational modifications. Micro-RNA (miRNA)-mediated posttranscriptional gene regulation has emerged as a fundamental mechanism controlling normal tissue development and function. Emerging evidence indicates that miRNAs are expressed within the organs of the female reproductive tract where they function to regulate cellular pathways necessary for proper function of these organs. In this review, the functional significance of miRNAs in the development and function of the organs of the female reproductive tract is discussed. Initial discussion focuses on the role of miRNAs in the development of the organs of the female reproductive tract highlighting recent studies that clearly demonstrate that mice with disrupted Dicer1 expression are sterile, fail to develop uterine glands, and have muted estrogen responsiveness. Next, emphasis moves to discussion on our current knowledge on the characterization of miRNA expression in each of the organs of the female reproductive tract. When possible, information is presented and discussed with respect to regulation, function, and/or functional targets of these miRNA within each specific organ of the female reproductive tract.
