Abstract
STUDY QUESTION Does platelet-rich plasma (PRP) intraovarian injection increase the number of retrieved oocytes in successive ovarian punctions among patients with poor ovarian reserve (POR)? SUMMARY ANSWER The injection of PRP increases the number of retrieved oocytes without increasing the quality of developed blastocysts. WHAT IS KNOWN ALREADY Management of women with reduced ovarian response to stimulation is one of the significant challenges in reproductive medicine. Recently, PRP treatment has been proposed as an adjunct in assisted reproduction technology, with controversial results. STUDY DESIGN, SIZE, DURATION This placebo-controlled, double-blind, randomized trial included 60 patients with POR stratified according to the POSEIDON classification groups 3 and 4. It was conducted to explore the efficacy and safety of intraovarian PRP injection. Patients were proposed to undergo three consecutive ovarian stimulations to accumulate oocytes and were randomized to receive either PRP or placebo during their first oocyte retrieval. Randomization was performed using computer-generated randomization codes. Double blinding was ensured so that neither the participant nor the investigators knew of the treatment allotted. All patients underwent three ovarian stimulations and egg retrieval procedures. ICSI was performed after a third ovarian puncture. The primary endpoint was the number of mature oocytes retrieved after PRP or placebo injection in successive ovarian punctures. PARTICIPANTS/MATERIALS, SETTING, METHODS Sixty women (30-42 years) fulfilling inclusion criteria were randomized in equal proportions to the treatment or control groups. MAIN RESULTS AND THE ROLE OF CHANCE The baseline demographic and clinical characteristics [age, BMI, anti-Müllerian hormone (AMH) levels] were comparable between the groups. Regarding the primary endpoint, the cumulative number (mean ± SEM) of retrieved mature oocytes was slightly higher in the treatment group: 10.45 ± 0.41 versus 8.91 ± 0.39 in the control group, respectively (95% CI of the difference 0.42-2.66; P = 0,008). The number of mature oocytes obtained among all patients increased in successive egg retrievals: 2.61 ± 0.33 (mean ± SEM) in punction 1 (P1), 3.85 ± 0.42 in P2, and 4.73 ± 0.44 in P3. However, the increase was higher among patients receiving the assessed PRP treatment. In P2, the number of retrieved mature oocytes was 4.18 ± 0.58 versus 3.27 ± 0.61 in controls (95% CI of the difference: -0.30 to 2.12; P = 0.138) and in P3, 5.27 ± 0.73 versus 4.15 ± 0.45 (95% CI of the difference: 0.12-2.12; P = 0.029). The mean ± SEM number of developed and biopsied blastocysts was 2.43 ± 0.60 in the control group and 1.90 ± 0.32 in the treatment group, respectively (P = 0.449). The mean number of euploid blastocysts was 0.81 ± 0.24 and 0.81 ± 0.25 in the control and treatment groups, respectively (P = 1.000). The percentages of patients with euploid blastocysts were 53.33% (16 out of 30) and 43.33% (13 out of 30) for patients in the control and treatment groups, respectively (Fisher's exact test P = 0.606). The overall pregnancy rate per ITT was 43% (26 out of 60 patients). However, the percentage of clinical pregnancies was higher in the control group (18 out of 30, 60%) than in the treatment group (8 out of 30, 27%) (P = 0.018). There was also a trend toward poorer outcomes in the treatment group when considering full-term pregnancies (P = 0.170). There were no differences between control and treatment groups regarding type of delivery, and sex of newborns. LIMITATIONS, REASONS FOR CAUTION The mechanism of the potential beneficial effect of PRP injection on the number of retrieved oocytes is unknown. Either delivered platelet factors or a mechanical effect could be implicated. Further studies will be needed to confirm or refute the data presented in this trial and to specify the exact mechanism of action, if any, of PRP preparations. WIDER IMPLICATIONS OF THE FINDINGS The increasing number of women with a poor response to ovarian stimulation supports the exploration of new areas of research to know the potential benefits of therapies capable of increasing the number of oocytes available for fertilization and improving the quality of developed blastocysts. An increase in the retrieved oocytes in both arms of the trial suggests that, beyond the release of growth factor from platelets, a mechanical effect can play a role. However, neither improvement in euploid blastocyst development nor pregnancy rates have been demonstrated.

Abstract
It is well known that female reproduction ability decreases during the forth decade of life due to age-related changes in oocyte quality and quantity; although the number of women trying to conceive has today increased remarkably between the ages of 36 to 44. The causes of reproductive aging and physiological aspects of this phenomenon are still elusive. With increase in the women's age, during Assisted Reproductive Technologies (ART) we have perceived a significant decline in the number and quality of retrieved oocytes, as well as in ovarian follicle reserves. This is because of increased aneuploidy due to factors such as spindle apparatus disruption; oxidative stress and mitochondrial damage. The aim of this review paper is to study data on the potential role of the aging process impacting oocyte quality and female reproductive ability. We present the current evidence that show the decreased oocyte quality with age, related to reductions in female reproductive outcome. The aging process is complicated and it is caused by many factors that control cellular and organism life span. Although the factors responsible for reduced oocyte quality remain unknown, the present review focuses on the potential role of ovarian follicle environment, oocyte structure and its organelles. To find a way to optimize oocyte quality and ameliorate clinical outcomes for women with aging-related causes of infertility.

Abstract
This study was designed to understand the efficacy and molecular cues of melatonin in cyclophosphamide(CTX)-induced premature ovarian failure (POF) in rats. Female SD rats were used to evaluate the potential effects of melatonin on the ovarian hormonal status, follicular development, and granulosa cells in CTX-treated rats. Here, we found that pretreatment with melatonin before CTX administration preserved the normal sex hormone levels, improved follicular morphology, and granulosa cell proliferation, and reduced apoptosis, as compared to the CTX treatment alone. Additionally, melatonin also up-regulated CYR6 and CTGF at the mRNA and protein levels. A potential mechanism is that melatonin inhibits LATS1, Mps1-One binder (MOB1), and YAP phosphorylation, thereby activating the Hippo signal pathway to promote its downstream targets, CYR61 and CTGF. In conclusion, pretreatment with melatonin effectively protected the ovaries against CTX-induced damage by activating the Hippo pathway. This study lay the foundation for the clinical application of melatonin for cancer patients with CTX treatment.

Cell Biol Int 2020; 45:127-139. [PMID: 32997425 DOI: 10.1002/cbin.11475] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2020] [Revised: 09/27/2020] [Accepted: 09/28/2020] [Indexed: 12/12/2022]
Abstract
Follicular fluid (FF) is essential for developing ovarian follicles. Besides the oocytes, FF has abundant undifferentiated somatic cells containing stem cell properties, which are discarded in daily medical procedures. Earlier studies have shown that FF cells could differentiate into primordial germ cells via forming embryoid bodies, which produced oocyte-like cells (OLC). This study aimed at isolating mesenchymal stem cells (MSC) from FF and evaluating the impacts of bone morphogenetic protein 15 (BMP15) on the differentiation of these cells into OLCs. Human FF-derived cells were collected from 78 women in the assisted fertilization program and cultured in human recombinant BMP15 medium for 21 days. Real-time polymerase chain reaction and immunocytochemistry staining characterized MSCs and OLCs. MSCs expressed germline stem cell (GSC) markers, such as OCT4 and Nanog. In the control group, after 15 days, OLCs were formed and expressed zona pellucida markers (ZP2 and ZP3), and reached 20-30 µm in diameter. Ten days after induction with BMP15, round cells developed, and the size of OLCs reached 115 µm. A decrease ranged from 0.04 to 4.5 in the expression of pluripotency and oocyte-specific markers observed in the cells cultured in a BMP15-supplemented medium. FF-derived MSCs have an innate potency to differentiate into OLCs, and BMP15 is effective in promoting the differentiation of these cells, which may give an in vitro model to examine germ cell development.

Abstract
Data on the substantial physiological role of the immune system in the organism's ability to manage proper differentiation and function of normal tissues (tissue homeostasis), and detailed causes of the immune system's essential role for the in-vivo stimulation of cancer growth, are severely lacking. This results in a lack of effective cancer immunotherapy without adverse events, and in the lack of long-lasting cancer immune prophylaxes, particularly in ovarian cancers. Elimination of blood auto-antibodies blocking anti-cancer T cell effectors by intermittent moderate doses of cyclophosphamide, facilitation of the immune system reactivity against alloantigens of cancer cells by two subsequent blood transfusions, and augmentation of anticancer immunity by weekly intradermal injections of bacterial toxins, caused during the subsequent treatment-free period, lasting for two to four weeks, regression of inoperable epithelial ovarian cancers and regeneration of the tremendously metastatically altered abdominal tissues into normal healthy conditions without multivisceral cytoreductive surgery, which can result in life-threatening consequences. An otherwise untreated rectal cancer, progressing over 3 years, regressed after severe toxic dermatitis lasting over one week. This was caused by an accidental consumption of a large raw shiitake mushroom. Subsequent daily consumptions of 2 g Metformin ER and honeybee propolis ethanol extract, and weekly single larger raw shiitake mushroom, which all stimulate immune system reactivity against cancer stem cells, prevented malignant recurrence over the next 29 years without recurring dermatitis, and maintained healthy organism's conditions. These observations indicate that regression of advanced inoperable cancers and long-lasting cancer immune prophylaxis can be reached by simple approaches.

Abstract
PURPOSE We evaluated the protective effect of PRP on ovarian function in female rats with cyclophosphamide (Cy)-induced ovarian damage. METHODS Thirty-two adult female Sprague-Dawley rats were randomly divided into four groups. Group 1 (control-sodium chloride 0.9%; 1 mL/kg, single-dose ip injection), group 2 (Cy); 75 mg/kg, single-dose ip injection and sodium chloride 0.9% (1 mL/kg, single-dose ip injection), group 3 Cy plus PRP, Cy (75 mg/kg, single-dose and PRP (200 μl, single-dose) ip injection), group 4 (PRP, 200 μl, single-dose ip injection). Primordial, antral, and atretic follicle counts; serum anti-Müllerian hormone (AMH) levels; AMH-positive granulosa cells; and gene expression analysis of Ddx4 were assessed. RESULTS Serum AMH levels were significantly lower in group 2 compared to groups 1, 3, and 4 (p < 0.01, p < 0.01, and p = 0.04, respectively). A significant difference was found in the primordial, primary, secondary, antral, and atretic follicle counts between all groups (p < 0.01). There was a statistically significant difference in AMH-positive staining primary, secondary, and antral follicles count between the groups (p < 0.01). There was a statistically significant difference in primary, secondary, and antral AMH positive staining follicle intensity score between the groups (p < 0.01). Ddx4 expression in group 4 was highest compared to other groups. CONCLUSION Our study may provide evidence that PRP could protect ovarian function against ovarian damage induced by Cy. It could lead to improved primordial, primary, secondary, and antral follicle numbers.

Abstract
This review highlights the challenges, priority areas of research and planning, strategies for regulation of services and the need to develop guidelines and laws for fertility treatments during mid-life. The success rate of all treatments is poor in advanced age women because of declining ovarian reserve and natural fertility. There is often a need of third-party involvement which has its own ethical, legal and medical issues. Welfare of children born to older women and early death of parents are important concerns. Most of the new techniques such as the pre-implantation genetic diagnosis, oocyte augmentation, use of stem cells or artificial gametes, ovarian tissue preservation and ovarian transplantation are directed to improve, preserve or replace the declining ovarian reserve. These techniques are costly and have limited availability, safety and efficacy data. Continued research and policies are required to keep pace with these techniques. The other important issues include the patients’ personal autonomy and right of self-determination, welfare of offspring, public vs. private funding for research and development of new technologies vs. indiscriminate use of unproven technology. It is important that mid-life fertility is recognized as a distinct area of human reproduction requiring special considerations.

Abstract
Fertility preservation research in women today is increasingly taking advantage of bioengineering techniques to develop new biomimetic materials and solutions to safeguard ovarian cell function and microenvironment in vitro, and in vivo,. However, available data on the human ovary are limited and fundamental differences between animal models and humans are hampering researchers in their quest for more extensive knowledge of human ovarian physiology and key reproductive proteins that need to be preserved. We therefore turned to multi-dimensional label-free mass spectrometry to analyze human ovarian cortex, as it is a high-throughput and conclusive technique providing information on the proteomic composition of complex tissues like the ovary. In-depth proteomic profiling through two-dimensional liquid chromatography-mass spectrometry, Western blotting, histological and immunohistochemical analyses, and data mining helped us to confidently identify 1508 proteins. Moreover, our method allowed us to chart the most complete representation so far of the ovarian matrisome, defined as the ensemble of extracellular matrix proteins and associated factors, including more than 80 proteins. In conclusion, this study will provide a better understanding of ovarian proteomics, with a detailed characterization of the ovarian follicle microenvironment, in order to enable bioengineers to create biomimetic scaffolds for transplantation and three-dimensional in vitro, culture. By publishing our proteomic data, we also hope to contribute to accelerating biomedical research into ovarian health and disease in general.

Abstract
The aim of the study was to investigate the inhibitory effects of soybean isoflavones (SI) on testicular cell apoptosis in mice with type-2 diabetes, as well as any possible mechanisms of action. Thirty male C57BL/6J mice were randomly divided into the control, diabetic (model), and treatment (SI) groups (n=10 each). After treatment for 20 weeks, testicular cell apoptosis was detected and evaluated using DAPI staining. The expression and distribution of caspase-3 protein in testicular tissues was detected via immunohistochemistry, while caspase-3 mRNA expression was detected using RT-PCR. Bax and Bcl-2 protein expression was detected by western blot analysis. At week 20, DAPI staining showed that SI treatment significantly decreased testicular tissue cell apoptosis in diabetic mice. Immunohistochemical staining revealed that caspase-3 expression in the SI group was significantly reduced relative to the model group. RT-PCR showed that SI treatment significantly decreased caspase-3 mRNA expression relative to the model group. Western blot analysis revealed that SI treatment significantly decreased Bax protein expression and increased Bcl-2 protein expression (P<0.01). SI exhibited an inhibitory effect on testicular tissue cell apoptosis in mice with type 2 diabetes, with this effect possibly mediated by a decreased expression of caspase-3 and Bax and increased Bcl-2 protein expression.

Abstract
For many decades, the dogma prevailed that female mammals had a finite pool of oocytes at birth and this was gradually exhausted during a lifetime of reproductive function. However, in 2004, a new era began in the field of female oogenesis. A study was published that appeared to detect oocyte-stem cells capable of generating new eggs within mouse ovaries. This study was highly controversial and the years since this initial finding have produced extensive research and even more extensive debate into their possibility. Unequivocal evidence testifying to the existence of oocyte-stem cells (OSCs) has yet to be produced, meanwhile the spectrum of views from both sides of the debate are wide-ranging and surprisingly passionate. Although recent studies have presented some convincing results that germ cells exist and are capable of creating new oocytes, many questions remain. Are these cells present in humans? Do they exist in physiological conditions in a dormant state? This comprehensive review first examines where and how the dogma of a finite pool was established, how this has been challenged over the years and addresses the most pertinent questions as to the current status of their existence, their role in female fertility, and perhaps most importantly, if they do exist, how can we harness these cells to improve a woman's oocyte reserve and treat conditions such as premature ovarian insufficiency (POI: also known as premature ovarian failure, POF).

Abstract
Blood mononuclear cells consist of T cells and monocyte derived cells. Beside immunity, the blood mononuclear cells belong to the complex tissue control system (TCS), where they exhibit morphostatic function by stimulating proliferation of tissue stem cells followed by cellular differentiation, that is stopped after attaining the proper functional stage, which differs among various tissue types. Therefore, the term immune and morphostatic system (IMS) should be implied. The TCS-mediated morphostasis also consists of vascular pericytes controlled by autonomic innervation, which is regulating the quantity of distinct tissues in vivo. Lack of proper differentiation of tissue cells by TCS causes either tissue underdevelopment, e.g., muscular dystrophy, or degenerative functional failures, e.g., type 1 diabetes and age-associated diseases. With the gradual IMS regression after 35 years of age the gonadal infertility develops, followed by a growing incidence of age-associated diseases and cancers. Without restoring an altered TCS function in a degenerative disease, the implantation of tissue-specific stem cells alone by regenerative medicine can not be successful. Transfused young blood could temporarily restore fertility to enable parenthood. The young blood could also temporarily alleviate aging diseases, and this can be extended by substances inducing IMS regeneration, like the honey bee propolis. The local and/or systemic use of honey bee propolis stopped hair and teeth loss, regressed varicose veins, improved altered hearing, and lowered high blood pressure and sugar levels. Complete regression of stage IV ovarian cancer with liver metastases after a simple elaborated immunotherapy is also reported.

Intrauterine administration of hCG immediately after oocyte retrieval and the outcome of ICSI: a randomized controlled trial. Hum Reprod 2016; 31:2520-2526. [PMID: 27680029 DOI: 10.1093/humrep/dew236] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2016] [Revised: 08/16/2016] [Accepted: 08/25/2016] [Indexed: 12/28/2022] Open
Abstract
STUDY QUESTION Does the intrauterine administration of hCG immediately after oocyte retrieval in antagonist cycles with ICSI and fresh embryo transfer (ET) influence the implantation rate or chemical and clinical pregnancy rates? SUMMARY ANSWER The intrauterine administration of hCG after oocyte retrieval increases the implantation rate and chemical and clinical pregnancy rates. WHAT IS KNOWN ALREADY Over half of IVF/ICSI cycles fail due to implantation failure. Intrauterine administration of hCG, a few minutes before ET, increased the implantation and pregnancy rates in most but not in all studies. The effect of intrauterine administration of hCG, after oocyte retrieval, has not yet been studied. STUDY DESIGN, SIZE, DURATION The study was a parallel, triple-blind randomized clinical trial (RCT) performed from September 2015 to February 2016, in a university hospital. We recruited women undergoing antagonist ovarian stimulation, ICSI and ET. For an effect size of 0.2, power of 80% at a significance level of 0.05, we needed 150 participants. Accounting for a 7% dropout rate, a total of 160 women was considered appropriate. A computer-generated randomization list with a block size of 4, with 1:1 allocation was used. The treatment allocation was placed in a sealed, opaque, envelope and picked up consecutively. Immediately after oocyte retrieval, patients in the intervention and control groups were treated with intrauterine injection of hCG and saline, respectively. Participants underwent ET on Day 3. A beta-hCG test was done at 2 weeks. If positive, three transvaginal-ultrasonographies (TVSs) were done at 3, 4 and 10 weeks after ET. The participants were called up thereafter and questioned about the continuity of their pregnancy. PARTICIPANTS/MATERIALS, SETTING, METHOD Of 1990 women attending the infertility clinic of our university hospital, 508 were IVF/ICSI candidates during the study period, and 245 of the patients on an antagonist cycle met the criteria to be invited into our trial. Inclusion criteria were normal ovarian reserve, age ≤41, undergoing ICSI, and fresh ET and normal TSH and prolactin. Uncontrolled chronic disease, severe hydrosalpinx, severe endometriosis, morphologic embryo deficiencies, non-obstructive azospermia and high risk of severe ovarian hyperstimulation syndrome were criteria for exclusion. After taking an informed consent, a total of 158 participants were recruited, of which 80 were randomly allocated to receive intrauterine 500 IU hCG in up to 0.5 ml normal saline and 78 to receive intrauterine 0.5 ml normal saline immediately after oocyte retrieval, during general anaesthesia. ICSI was performed conventionally. The 4-8 cell embryos were transferred on the third day after oocyte retrieval. Implantation rate, chemical and clinical pregnancy rates were analysed and compared between the two groups. MAIN RESULTS AND THE ROLE OF CHANCE Patients' demographic and baseline characteristics were comparable. The clinical results showed statistically significant differences between the two groups regarding the biochemical pregnancy rate (59.2 versus 31.3%; P = 0.001; odds ratio (OR) = 1.88; 95% CI, 1.26-2.82; risk difference (RD) = 27.8; 95% CI, 11.2-42.3), implantation rate (37 versus 17%; P = 0.012; OR = 2.29; 95% CI, 1.02-5.14; RD = 20.2; 95% CI, 5.4-33.8), clinical pregnancy rate (50.7 versus 16.4%; P < 0.001; OR = 3.08; 95% CI, 1.71-5.55; RD = 34.3; 95% CI, 18.7-47.6) and ongoing pregnancy rate (40.1 versus 13.4%; P = 0.001; OR = 3.04; 95% CI, 1.55-5.93; RD = 27.4; 95% CI, 12.7-40.6). The abortion and ectopic pregnancy rates were not statistically different between the two groups. LIMITATIONS, REASONS FOR CAUTION The insertion of an intrauterine insemination catheter and the injection of a small amount of saline into the uterine cavity (without hCG) may also have some impact on implantation. This effect could be studied by comparing this intervention with another study group without any intrauterine injection.There are no specific side effects mentioned in the literature for the intrauterine administration of hCG, neither were any observed in our study, but it is best to be cautious about probable side effects, because this type of intervention is relatively new and experimental, and deserves more studies before being entered into routine clinical practice. WIDER IMPLICATIONS OF THE FINDINGS Intrauterine administration of hCG immediately after oocyte pick up increases its effectiveness; however, further investigations are required before this procedure can be recommended for clinical practice. STUDY FUNDING/COMPETING INTERESTS This study was supported by the Women's Health Research Center, Tabriz University of Medical Sciences, Iran. No external funds were used. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER IRCT201206165485N4. TRIAL REGISTRATION DATE 2 September 2015. DATE OF FIRST PATIENT'S ENROLMENT 2 September 2015.

Abstract
In addition to its role in maintaining organism homeostasis, the immune system also plays a crucial role in the modulation of ovarian function, as it regulates ovarian development, follicular maturation, ovulation and the formation of the corpus luteum. Ovarian germline stem cells are pluripotent stem cells derived from the ovarian cortex that can differentiate into ovarian germ cells and primary granulosa cells. Recent work has demonstrated that the proliferation and differentiation of ovarian germline stem cells is regulated in part by immune cells and their secreted factors. This paper reviews the role of the immune system in the regulation of ovarian function, the relationship between immune components and ovarian germline stem cells and current research efforts in this field.
