This article investigates the transformative impact of 3D and bio 3D printing technologies in assisted reproductive technology (ART), offering a comprehensive review of their applications in improving reproductive outcomes. Following PRISMA guidelines, we conducted a thorough literature search focusing on the intersection of ART and additive manufacturing, resulting in the inclusion of 48 research papers. The study highlights bio 3D printing's potential in revolutionizing female infertility treatments, especially in follicle complex culture and ovary printing.

We explore the intricate interplay between these two seemingly distinct medical conditions, shedding light on their shared risk factors and potential pathophysiological connections. A specific connection between hypertension (HTN), atrial fibrillation (AF), myocardial infarction (MI), and breast cancer was evaluated.

The condition is characterized by the loss of ovarian function before the age of 40 years and several factors have been identified to be implicated in its pathogenesis. Remarkably though, at least 50% of women have remaining follicles in their ovaries after the development of ovarian insufficiency.

AIs have demonstrated superior efficacy when used as adjuvant endocrine therapy or monotherapy for postmenopausal patients with hormone receptor (HR)-positive early-stage breast cancer, although various side effects have been recorded.
Materials And Methods: Fifty-five adult female Wistar rats were randomized and assigned into four groups.
Background/aim: Soy contains genistein and daidzein isoflavones. Isoflavones are phytoestrogens, with a similarity in structure to human 17-β estradiol hormone. They imitate the action of estrogen on organs by binding and activating estrogen receptors.

Galectin-3 is expressed by different human tissues. It plays a significant role in carcinogenesis and the selection of tumor-related physiological and pathological activities.

The aim of the study was to compare demographic, hormonal and clinical parameters in patients with premature ovarian insufficiency (POI) and women with early menopause in Greece. One hundred thirty-nine women of Greek origin, aged 14-45 years, referring for oligomenorrhea and having elevated FSH concentrations were divided into three groups regarding the age of menstrual disturbances onset [POI: =30 years ( = 42); POI: 31-39 years ( = 36); early menopause: 40-45 years ( = 61)]. The mean age of menstrual disturbances onset and that of diagnosis in all POI and early menopause patients were 28.

We have previously shown that the intrauterine administration of PBMC treated with corticotropin-releasing hormone (CRH) prior to blastocyst transfer (day 5) improves significantly the clinical pregnancy rate of women with RIF. In the present crossover pilot study, we have investigated whether CRH-PBMC treatment could be of benefit in case of fresh early cleavage stage embryo transfer (day 3) in women with RIF.
View Article and Find Full Text PDFEndometrial corticotropin-releasing hormone (CRH) has been described as a mediator of decidualisation and as a contributor of maternal-fetal immunotolerance. Deregulation of the CRH expression pattern has been associated with unfavourable reproductive outcomes as well as chronic endometrium-derived inflammatory disorders, such as endometriosis and adenomyosis. The current review summarises the evidence produced regarding the role of CRH in endometrial physiology and pathophysiology and highlights recent clinical data regarding the role of CRH in improving clinical pregnancy rates in women with repeated implantation failures following in vitro fertilisation and embryo transfer.

One of the key molecules during this process is human chorionic gonadotropin (HCG). HCG effectively modulates several metabolic pathways within the decidua contributing to endometrial receptivity.

Background: Corticotropin releasing hormone (CRH), the main peptide-mediator of stress, has been found in the female reproductive system.
Objective: Herein, the role of CRH receptors in the female reproductive system is presented.
Results: It is clear that CRH receptors are involved in the regulation of the hypothalamic-pituitaryovarian axis, while locally are associated with decidualization, embryonic implantation, early fetal development and triggering of parturition.
Background: Previous studies have shown that the intrauterine administration of peripheral blood mononuclear cells (PBMC) may improve pregnancy outcome of women with repeated implantation failure (RIF). We have demonstrated that, during implantation, corticotropin-releasing hormone (CRH) plays a key role in facilitating endometrial decidualization and maternal-foetal immunotolerance. In the present preliminary study, we investigated whether the intrauterine administration of autologous CRH-treated PBMC can improve clinical pregnancy rates of women with RIF.

Objective: The objective of the study was to evaluate the efficacy of hormone replacement in maintaining BMD in these young women.
Objective: Women with primary ovarian insufficiency (POI) display low androgen levels, which could contribute to mood and behavioral symptoms observed in this condition. We examined the effects of physiologic testosterone therapy added to standard estrogen/progestin therapy on quality of life, self-esteem, and mood in women with POI.
Methods: One hundred twenty-eight women with 46,XX spontaneous POI participated in a 12-month randomized, placebo-controlled, parallel-design investigation of the efficacy of testosterone augmentation of estrogen/progestin therapy.
Objective: To investigate the effect of metformin administration on the expression of endometrial corticotrophin-releasing hormone (CRH) and urocortin (UCN) in the midluteal phase of the cycle.
Design: Experimental study, performed in 2010-2011.
Setting: University hospital.
Context: Menopause has been related to an increased atherosclerotic risk. Presence and severity of hot flushes in menopausal women have been associated with impaired endothelial function and advanced subclinical atherosclerosis.
Objective: The objective of the study was to evaluate the effect of menopausal transition on vascular inflammation indices and investigate the association of hot flush severity with these indices in early menopausal women.
Objective: Hormone therapy (HT) has been suggested to improve vascular function and inflammation in menopausal women, although not consistently. We aimed to investigate the effects of HT on endothelial function and inflammation, especially sCD40L, in early menopausal women, and the effect of common estrogen receptor (ER) polymorphisms on vascular responses to HT.
Study Design: Eighty-four early menopausal women (<3 years in menopause) with menopausal complaints eligible for HT.

Purpose: Sperm flow cytometry (SFC) was used to evaluate the association of sperm chromatin condensation and ploidy with fertilization, embryo development, pregnancy and abortion rates following IVF.
Methods: Conventional semen analysis was performed in one hundred fifty men, as well as SFC analysis, after acridine orange and propidium iodide staining, for the evaluation of sperm maturity and ploidy respectively. Conventional IVF was performed in all couples.
Background: Combined oral contraceptives are used in polycystic ovary syndrome (PCOS) women for the treatment of hyperandrogenism and menstrual cycle disturbances.
Aim: To assess the effect of ethinylestradiol and cyproterone acetate (EE/CA) on endothelial function in young, non-obese PCOS women in a pilot study.
Methods: Thirteen young, non-obese PCOS women (20.
