Yuan WS, Abu MA, Ahmad MF, Elias MH, Abdul Karim AK. Effects of Dehydroepiandrosterone (DHEA) Supplementation on Ovarian Cumulus Cells following In Vitro Fertilization (IVF)/Intra-Cytoplasmic Sperm Injection (ICSI) Treatment-A Systematic Review. Life (Basel) 2023; 13:1237. [PMID: 37374020 DOI: 10.3390/life13061237] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 05/01/2023] [Accepted: 05/04/2023] [Indexed: 06/29/2023] Open
Abstract
Despite many studies exploring the effects of DHEA supplementation, its application in IVF procedure continues to be a subject of debate owing to the inconsistent findings and the lack of rigorously designed, large-scale, randomized trials. Our review aims to explore the effectiveness of DHEA supplementation in ovarian cumulus cells following IVF/ICSI treatment. We conducted a literature search of Pub-Med, Ovid MEDLINE, and SCOPUS (inception to June 2022) for all relevant articles, including the keywords of "dehydroepiandrosterone/DHEA", "oocyte", and "cumulus cells". From the preliminary search, 69 publications were identified, and following a thorough screening process, seven studies were ultimately incorporated into the final review. Four hundred twenty-four women were enrolled in these studies, with DHEA supplementation being administered exclusively to women exhibiting poor ovarian response/diminished ovarian reserve or belonging to an older age demographic. The intervention in the studies was DHEA 75-90 mg daily for at least 8-12 weeks. The only randomized controlled trial showed no difference in clinical or cumulus cell-related outcomes between the control and treatment groups. However, the remaining six studies (two cohorts, four case-controls) showed significant beneficial effects of DHEA in cumulus cell-related outcomes compared to the group (older age or POR/DOR) without DHEA supplementation. All studies revealed no significant difference in stimulation and pregnancy outcomes. Our review concludes that DHEA supplementation did show beneficial effect on ovarian cumulus cells in improving oocyte quality for women of advanced age or with poor ovarian responders.

Effect of bisphenol A on alterations of ICAM-1 and HLA-G genes expression and DNA methylation profiles in cumulus cells of infertile women with poor response to ovarian stimulation. Sci Rep 2021; 11:9595. [PMID: 33953208 PMCID: PMC8099902 DOI: 10.1038/s41598-021-87175-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Accepted: 03/25/2021] [Indexed: 12/27/2022] Open
Abstract
This study aimed to investigate the relationship between follicular fluid Bisphenol A (BPA) concentrations with alterations of ICAM-1 and HLA-G genes and proteins expression as well as methylation profiles in the cumulus cells of poor ovarian response (POR) women based on their healthy lifestyle habit. Eighty women under the age of 35 were divided into two groups: 1-POR without using plastic containers (n = 40) and 2-POR with using plastic containers (n = 40). The ICAM-1 and HLA-G genes and protein expressions were examined by the quantitative PCR and western blotting technique. The methylation pattern was investigated by the methylation-specific PCR. Total BPA in follicular fluid was measured with high-performance liquid chromatography technique and the detection limit was 1.14 ng/ml. ICAM-1 and HLA-G genes were differentially expressed between the two groups studied. ICAM-1, HLA-G genes, and protein expressions in group 1 were up-regulated compared to the second group (P < 0.05). While DNA methylation status in group 1 were decreased compared to the other group (P < 0.05). The concentration of BPA in the follicular fluid of group 1 was lower compared to the second group (P < 0.05). The oocyte quality and clinical pregnancy ratio showed significantly higher in group 1 than in the other ones (P < 0.05). The alteration of ICAM-1 and HLA-G gene expressions in POR women is probably related to BPA concentration. As a result Lifestyle habits may also affect the methylation pattern and protein levels in the cumulus cells of POR women. Additionally, lifestyle habits may be considered as a marker for ovulation, oocyte maturation, preimplantation, and clinical pregnancy process.

Abstract
DNA methylation can regulate gene expression and is pivotal in the occurrence and development of bladder cancer. In this study, we analyzed whole-genome DNA methylation on the basis of data from The Cancer Genome Atlas to select epigenetic biomarkers predictive of survival and further understand the molecular mechanisms underlying methylation patterns in bladder cancer. We identified 540 differentially methylated genes between tumor and normal tissues, including a number of independent prognostic factors based on univariate analysis. Genes (MIR6732, SOWAHC, SERPINI1, OR10W1, OR7G3, AIM1, and ZFAND5) were integrated to establish a risk model for prognostic assessment based on multivariate Cox analysis. The methylation of SOWAHC was negatively correlated with its messenger RNA expression, and together these were significantly correlated with prognosis. This study took advantage of high-throughput data mining to provide new bioinformatics evidence and ideas for further study into the pathogenesis and prognosis of bladder cancer.

Abstract
Background Women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) with poor ovarian respond (POR) always have very low clinical pregnancy rates. In previous data, dehydroepiandrosterone (DHEA) was suggested as a promising treatment and maybe has a good pregnancy outcome. But there is no sufficient evidence from randomized clinical trials evaluating the effect of DHEA preconceptional treatment on live birth in POR. Methods This trial is a multicenter active-placebo double-blind clinical trial (1:1 treatment ratio of active versus placebo). The infertile POR patients undergoing IVF or ICSI will be enrolled and randomly assigned to two parallel groups. Participants in these two groups will be given 4–12 weeks’ treatment of DHEA or placebo, respectively. The primary outcome is live birth rate. Discussion The results of this study will provide evidence for the effect of preconceptional DHEA treatment on IVF outcome in POR.

Abstract
Background: This study was performed to evaluate the role of luteinizing hormone (LH) and granulosa cell LH receptor (LH-R) in poor responder patients who underwent controlled ovarian stimulation. Expression levels of LH-R mRNA in granulosa cells was investigated and compared with oocyte morphology, oocyte maturity and fertilization rate. Methods: Granulosa cells were obtained from 30 patients who underwent in vitro fertilization (IVF) at Dr. Cipto Mangunkusumo Hospital, Jakarta. The patients were divided into two groups: group I (n=10) poor responders; and group II (n=20) non-poor responders. After the extraction of total RNA from granulosa cells, semi-quantitative RT-PCR was performed and the amount of LH-R mRNA was quantified. The relative values were calculated as the ratio of LH-R mRNA and actin beta mRNA. Statistical analysis was performed using Mann-Whitney test and Spearman correlation. Results: The relative value of LH-R mRNA was higher in group I compared with group II (27.37[0.00-28939.37] vs 0.00[0.00-7196.12]). Oocyte maturity (r=0.267) and morphology (r=0.267) in group I consistently showed a positive correlation with LH-R mRNA; in group II a negative correlation with LH-R mRNA was shown for oocyte maturity (r= -0.552) and morphology (r= -0.164). Group I had a positive correlation between LH-R expression with fertilization rate (r=0.430), and group II showed a negative correlation (r=-0.340). Conclusions: The expression of LH-R mRNA has a positive correlation with oocyte quality in poor responder patients and a negative correlation in non-poor responders. Our study suggests an optimal expression of LH- R mRNA in granulosa cells during controlled ovarian stimulation to obtain good quality oocytes.

Abstract
BACKGROUND Current methods for determining superior embryo quality (morphological assessment) are unable to compensate for poor pregnancy outcomes. Due to the importance of the cumulus-oocyte complex and the value of cumulus cells (CCs) as markers of embryo health, we determined the association between the CCs gene expression of the Prostaglandin-Endoperoxide Synthase 2 (PTGS2) and Versican (VCAN) with pregnancy. METHODS One hundred forty-nine women, suffering from infertility and undergoing IVF, were included in this study (age: 29-46 years; BMI = 25.5 ± 5.0 kg/m2). Patients underwent a standard IVF protocol. CCs were isolated during oocyte retrieval, and their RNA was isolated using Trizol. The mRNA expression of PTGS2, VCAN, and L19 was measured by qPCR. The PVL index, (PTGS2 + VCAN)*L19normalized, was determined for each oocyte. Clinical pregnancy was confirmed by β-hCG and the presence of a fetal heartbeat. Associations were determined by ROC curves or logistic regression. RESULTS There was no correlation between the PVL index and morphological scores. Using only single embryo transfers (SETs), we determined that the PVL index was associated with pregnancy (β-hCG: AUC = 0.87, 95%CI: 0.74-1.00) with an optimal cutoff value of 58.2. Using the complete cohort (consisting of SETs, and patients with 2, 3, or 4 embryos transferred), the presence of at least one embryo with a PVL index score ≥ 58.2 was associated with a greater probability of achieving pregnancy (β-hCG: odds ratio = 17.15, 95%CI: 6.82-43.18, p < 0.001). CONCLUSION Transferring at least one embryo with a PVL index score ≥ 58.2, generates a higher chance of achieving pregnancy.

Abstract
Mitochondrial dysfunction is related to reproductive decline in humans, with consequences for in vitro fertilization (IVF). We assessed whether dehydroepiandrosterone (DHEA) could regulate mitochondrial homeostasis and mitophagy of cumulus cells (CCs) in poor ovarian responders (PORs). A total of 66 women who underwent IVF treatment at the Reproductive Medicine Center of Kaohsiung Veterans General Hospital were included in this study. Twenty-eight normal ovarian responders (NOR) and 38 PORs were enrolled. PORs were assigned to receive DHEA supplementation (n = 19) or not (n = 19) before IVF cycles. DHEA prevents mitochondrial dysfunction by decreasing the activation of DNM1L and MFF, and increasing MFN1 expression. Downregulation of PINK1 and PRKN occurred after DHEA treatment, along with increased lysosome formation. DHEA not only promoted mitochondrial mass but also improved mitochondrial homeostasis and dynamics in the CCs of POR. We also observed effects of alterations in mRNAs known to regulate mitochondrial dynamics and mitophagy in the CCs of POR. DHEA may prevent mitochondrial dysfunction through regulating mitochondrial homeostasis and mitophagy.

Abstract
Because ovarian granulosa cells are essential for oocyte maturation and development, we validated human granulosa HO23 cells to evaluate the ability of the DHEA to prevent cell death after starvation. The present study was aimed to investigate whether DHEA could protect against starvation-induced apoptosis and necroptosis in human oocyte granulosa HO23 cells. The starvation was induced by treatment of serum-free (SF) medium for 4 h in vitro Starvation-induced mitochondrial depolarization, cytochrome c release and caspase-3 activation were largely prevented by DHEA in HO23 cells. We found that treatment with DHEA can restore starvation-induced reactive oxygen species (ROS) generation and mitochondrial membrane potential imbalance. In addition, treatment of DHEA prevents cell death via upregulation of cytochrome c and downregulation of BAX in mitochondria. Most importantly, DHEA is ameliorated to mitochondrial function mediated through the decrease in mitochondrial ROS, maintained mitochondrial morphology, and enhancing the ability of cell proliferation and ROS scavenging. Our present data strongly indicate that DHEA reduces programmed cell death (apoptosis and necroptosis) in granulosa HO23 cells through multiple interactions with the mitochondrion-dependent programmed cell death pathway. Taken together, our data suggest that the presence of DHEA could be beneficial to protect human oocyte granulosa HO23 cells under in vitro culture conditions during various assisted reproductive technology (ART) programs.Free Chinese abstract: A Chinese translation of this abstract is freely available at http://www.reproduction-online.org/content/154/2/101/suppl/DC1.

Utilization of the Bologna criteria: a promise unfulfilled? A review of published and unpublished/ongoing trials. Fertil Steril 2017; 109:104-109.e2. [PMID: 29198846 DOI: 10.1016/j.fertnstert.2017.09.024] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2017] [Revised: 09/19/2017] [Accepted: 09/20/2017] [Indexed: 12/27/2022]
Abstract
OBJECTIVE To study the use of the Bologna criteria (BC) for the definition of poor ovarian responders (POR) in clinical practice and research. DESIGN Systematic review of published and unpublished/ongoing trials between January 2012 and August 2017 on POR. SETTING Not applicable. PATIENT(S) Not applicable. INTERVENTION(S) The databases were searched using the relevant medical subject headings including all subheadings. The search was limited to humans and English language. The references of the included studies were cross-searched for possibly missed articles. Only clinical trials providing an evidence level ≥ III were included. Case reports, review, letters, and hypothetical articles were excluded. MAIN OUTCOME MEASURE(S) Extracted studies were divided into two groups: studies in which the BC were used or not. RESULT(S) One hundred nine published clinical studies analyzing a total of 30,540 women and 112 unpublished/ongoing trials were identified. The BC were used to define POR in 56 (51%) of the published and 44 (39%) of the unpublished trials. The use of the BC gradually increased from 29% to 53% from 2012 to 2017. Asian researchers were more likely to use the BC compared with European and North American researchers (65%, 49%, and 23%, respectively). Neither the design of the study nor the impact factor of the publishing journal was correlated with the use of the BC. CONCLUSION(S) There is still reluctance to use the BC for the definition of POR, which makes it difficult to combine data from small studies and reach a meaningful conclusion.

Abstract
Objective The effects of dehydroepiandrosterone (DHEA) supplementation in Saudi Arabian women with poor ovarian response (POR) is presently unknown. The present study aimed to assess the benefits of DHEA supplementation in women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Methods This was a prospective case-control study involving 62 women who were diagnosed with POR and underwent IVF/ICSI between January 2012 and June 2016. The positive influence of DHEA in 34 women, compared with 28 women without supplementation, was defined as improvements in the number of oocytes retrieved, the fertilization rate, the number of grade I embryos generated and the pregnancy rate. Results Both groups were evenly matched for age, body mass index and laboratory test parameters. There were statistically significant differences between the groups with and without DHEA supplementation for oocyte yield (6.35 ± 2.41 versus 3.98 ± 3.2), Grade I embryos generated (55% versus 30%), positive pregnancy rate (21/34 versus 10/28), and live birth rate (18/34 versus 4/28). Conclusion DHEA supplementation in women with POR had a positive effect on hormonal profiles, the quality of the endometrium, the number of oocytes retrieved, the quality of embryos, and the pregnancy and live birth rates.

Abstract
BACKGROUND Growing studies have demonstrated that dehydroepiandrosterone (DHEA) may improve fertility outcomes in poor ovarian responders (PORs). The aim of this study was to compare clinical outcomes and cumulus cell (CC) expression before and after DHEA treatment in PORs undergoing in vitro fertilization (IVF) cycles. METHODS Six patients with poor ovarian response were enrolled in the study according to Bologna criteria. DHEA was supplied at least 2 months before patients entered into the next IVF cycle. Expression of apoptosis-related genes in CCs was determined by quantitative real-time PCR. Mitochondrial dehydrogenase activity of CCs was assessed by cell counting kit-8 assay. RESULTS Metaphase II oocytes, maturation rate, embryos at Day 3, and fertilization rate significantly increased following DHEA treatment. Expression of cytochrome c, caspase 9, and caspase 3 genes in CCs were significantly reduced after DHEA therapy. Additionally, increased mitochondrial activity of CCs was observed following DHEA supplementation. CONCLUSIONS DHEA supplementation may protect CCs via improved mitochondrial activity and decreased apoptosis, leading to better clinical outcomes in PORs.

Abstract
Poor ovarian responders (PORs) pose a great challenge for in vitro fertilization (IVF). Previous studies have suggested that dehydroepiandrosterone (DHEA) may improve IVF outcomes in PORs. The current study attempted to investigate the clinical benefits of DHEA in PORs and the possible mechanisms of DHEA on cumulus cells (CCs). This was a prospective study performed at one tertiary center from January 2015 to March 2016. A total of 131 women who underwent IVF treatment participated, including 59 normal ovarian responders (NORs) and 72 PORs. PORs were assigned to receive DHEA supplementation or not before the IVF cycle. For all patients, CCs were obtained after oocyte retrieval. In the CCs, mRNA expression of apoptosis-related genes and mitochondrial transcription factor A (TFAM) gene, terminal deoxynucleotidyl transferase dUTP nick end labeling assay, mitochondrial dehydrogenase activity and mitochondrial mass were measured. The results indicated that PORs with DHEA supplementation produces a great number of top-quality embryos at day 3 and increased the number of transferred embryos and fertilization rate compared with those without DHEA supplementation. Additionally, supplementation with DHEA in PORs decreased DNA damage and apoptosis in CCs while enhancing the mitochondrial mass, mitochondrial dehydrogenase activity and TFAM expression in CCs. In conclusion, our results showed that the benefits of DHEA supplementation on IVF outcomes in PORs were significant, and the effects may be partially mediated by improving mitochondrial function and reducing apoptosis in CCs.

Abstract
Diminished ovarian reserve (DOR) has a high morbidity rate worldwide and has become a primary cause of infertility. DOR is a daunting obstacle in in vitro fertilization (IVF) and leads to poor ovarian response, high cancellation rates, poor IVF outcomes, and low pregnancy rates. Abnormal autoimmune function may also contribute to DOR. Dehydroepiandrosterone (DHEA) is a C19 androgenic steroid. DHEA is secreted mainly by the adrenal gland, and its secretion declines with age. DHEA has a pro-inflammatory immune function that opposes cortisol. The cortisol to DHEA ratio increases with age, which may lead to decreased immune function. DHEA supplementation helps improve this situation. A number of clinical case control studies and several prospective randomized clinical trials have observed a positive effect of DHEA supplementation in women with DOR. However, the underlying mechanism by which DHEA improves ovarian reserve remains unclear. DHEA functions as an immune regulator in many different tissues in mammals and may also play an important role in regulating the immune response in the ovaries. The conversion of DHEA to downstream sex steroids may allow it to regulate the immune response there. DHEA can also enhance the Th1 immune response and regulate the balance of the Th1/Th2 response. DHEA treatment can increase selective T lymphocyte infiltration in mice, resulting in a decline in the CD4+ T lymphocyte population and an upregulation of the CD8+ T lymphocyte population in ovarian tissue, thus regulating the balance of CD4+/CD8+ T cells. This review mainly focuses on how DHEA supplementation affects regulation of the immune response in the ovaries.

Abstract
Chromobox (Cbx) family proteins are transcriptional repressors that involved in epigenetic and developmental processes. In this study, comprehensive analyses of Cbxs were performed using available genome databases from representative animal species. The Cbx family were originated from one Polycomb (Pc) gene like the yeast Pc, which duplicated into two and gave rise to the Pc and the Heterochromatin protein 1 (Hp1) identified in invertebrates from protozoon to lancelet. Rapid expansion of Cbx family members was observed in vertebrates as ~8 (5 Pc and 3 Hp1) were identified in spotted gar, coelacanth and tetrapods. Further expansion of the members to ~14 (9 Pc and 5 Hp1) was observed in teleosts due to the third round genome duplication (3R). Based on transcriptome data from eight adult tilapia tissues, most of the Cbxs were found to be dominantly expressed in the brain, testis, ovary and heart. Analyses of the gonadal transcriptome data from four developmental stages revealed that all Cbxs were expressed in both ovary and testis except Cbx7b, with significant increase of the total and average RPKM from 5 to 90dah (days after hatching). By in situ hybridization, the three most highly and sexual dimorphically expressed Cbx genes in gonads, Cbx1b, Cbx3a and Cbx5, were found to be expressed in phase I and II oocytes of the ovary, and in secondary spermatocytes (Cbx1b and Cbx3a) and spermatids (Cbx5) of the testis. Our results revealed the evolution of Cbx genes and indicated a potential role of Cbxs in epigenetic regulation of gametogenesis.

Abstract
OBJECTIVE Embryo implantation is a complex process that requires coordinated trophoblast-endometrial interactions. Previous studies demonstrated that the identification of nitric oxide synthase (NOS) in trophoblast cells and the remodeling of the implantation process by nitric oxide (NO) support the important role of NO during implantation. However, the role of NO in trophoblast-endometrial interactions is unclear and is therefore examined in this study. MATERIALS AND METHODS We cocultured BeWo trophoblast spheroids with human umbilical vein endothelial cell (HUVEC) monolayers to mimic the trophoblast-endometrial interaction. N(ω)-Nitro-l-arginine methyl ester hydrochloride (l-NAME), a competitive inhibitor of NOS, and sodium nitroprusside (SNP), an NO donor, were used to test the role of NO in the trophoblast-endometrial interaction. RESULTS l-NAME diminished spheroid expansion on HUVEC monolayers in a concentration-dependent manner (p < 0.05). However, trophoblast spreading on HUVEC-free culture surfaces was unaffected by l-NAME treatment (p > 0.05). Significant suppression of spheroid expansion was found at the higher dose (1mM) of SNP (p < 0.05). CONCLUSION NO may be needed in the process of implantation, and an adequate but not overly NO-containing environment might be an important factor for successful implantation. This finding is worthy of further investigation.

Abstract
OBJECTIVE To investigate the effect of dehydroepiandrosterone (DHEA) supplementation on women with poor ovarian response (POR). MATERIALS AND METHODS Women with POR treated with flexible daily gonadotropin-releasing hormone antagonist in vitro fertilization (IVF) cycles at The Reproductive Center in Kaohsiung Veterans General Hospital between January 2013 and October 2013, were enrolled for this prospective study. When patients failed to become pregnant during the first IVF cycle, they were treated with DHEA supplementation (30 mg, 3 times a day, orally) for 3 months (mean 12.2 weeks) before the next IVF cycle. Parameters of biochemical, ultrasound and treatment outcomes were compared before and after DHEA supplementation. RESULTS Ten patients with a mean age of 36.6 ± 4.2 years were identified. After DHEA treatment, there was a significant increase in antral follicle count, from 2.8 ± 1.0 to 4.1 ± 1.2 (p < 0.05), and anti-Müllerian hormone, from 0.4 ± 0.2 ng/mL to 0.84 ± 0.2 ng/mL (p < 0.001). A significant decrease of Day 3 follicle-stimulating hormone and estradiol, from 14.4 ± 1.7 mIU/mL to 10.1 ± 0.7 mIU/mL and from 51.2 ± 6.3 pg/mL to 35.2 ± 4.2 pg/mL, respectively (both p < 0.001), was noted. Increased numbers of retrieved oocytes (from 2.4 ± 1.1 to 4.2 ± 1.2; p < 0.01), fertilized oocytes (from 1.7 ± 0.5 to 3.8 ± 1.1; p < 0.001), Day 3 embryos (from 1.7 ± 0.5 to 3.7 ± 1.1; p < 0.001) and transferred embryos (from 1.7 ± 0.8 to 2.8 ± 0.8; p < 0.01) were also seen in these women with POR after DHEA treatment. Three women became pregnant after DHEA treatment. CONCLUSION The potential benefits of DHEA supplementation in women with POR were suggested by the biochemical parameters and IVF outcomes.

Abstract
OBJECTIVE Our previous study showed the potential benefits of dehydroepiandrosterone (DHEA) supplementation in women with a poor ovarian response (POR). Because the connection between cumulus cells (CCs) and oocytes is a key step for oocyte maturation, we supposed that altered gene expression of CCs in women with POR after DHEA supplementation might favor oocyte maturation. MATERIALS AND METHODS Women with POR treated with flexible daily gonadotropin-releasing hormone antagonist in vitro fertilization (IVF) cycles at The Reproductive Center in Kaohsiung Veterans General Hospital, Kaohsiung, Taiwan between January 2013 and October 2013 were enrolled for this prospective study. CCs were isolated during IVF before and after DHEA (CPH-Formulation, Oakdale, CA, USA) supplementation. Nine genes of isolated CCs, including hyaluronan synthase (HAS2), versican (VCAN), thrombospondin 1 (THBS1), runt-related transcription factor 2 (RUNX2), chromobox homolog 3 (CBX3), tripartite motif-containing 28 (TRIM28), B-cell lymphoma 2 (BCL2), BCL2-associated X protein (BAX), and ankyrin repeat domain 57 (ANKRD57), were compared. RESULTS There was a significant difference in the expression of genes in women with POR before and after DHEA supplementation (all p < 0.05). All genes related to extracellular matrix (ECM) formation, including HAS2, VCAN, and THBS1, were upregulated. By contrast, all genes involving cell development, differentiation, and apoptosis regulation were downregulated. Unknown function gene ANKRD57 was also downregulated after DHEA supplementation. Although expressions of both BCL2 and BAX were decreased in women with POR after DHEA supplementation compared to those before treatment, the ratio of BCL2 and BAX was significantly increased in women with POR after DHEA supplementation, suggesting that DHEA supplementation might activate the antiapoptosis process of CCs, which might be beneficial to the improvement of ovarian function in women with POR. CONCLUSION The study showed that DHEA therapy positively affected the gene expression of CCs in women with POR, and provided evidence to support the positive effect of DHEA supplementation on women with POR.
