Chinese Medical Journal 2017;130(3):365-371
OBJECTIVEOvarian fibrosis is characterized by excessive proliferation of ovarian fibroblasts and deposition of extracellular matrix (ECM) and it is one of the principal reasons for ovarian dysfunction. This review aimed to investigate the pathogenetic mechanism of ovarian fibrosis and to clarify the relationship between ovarian diseases and fibrosis.
DATA SOURCESWe searched PubMed for English language articles published up to November 2016. The search terms included ovarian fibrosis OR fibrosis, ovarian chocolate cyst OR ovarian endometrioma, polycystic ovarian syndrome (PCOS), premature ovarian failure, ECM, matrix metalloproteinases (MMPs), tissue inhibitors of matrix metalloproteinases (TIMPs), transforming growth factor-beta 1 (TGF-β1), connective tissue growth factor (CTGF), peroxisome proliferator-activated receptor gamma (PPAR-γ), vascular endothelial growth factor (VEGF), endothelin-1 (ET-1), and combinations of these terms.
STUDY SELECTIONArticles were obtained and reviewed to analyze the pathogenic mechanism of ovarian fibrosis and related ovarian diseases.
RESULTSMany cytokines, such as MMPs, TIMPs, TGF-β1, CTGF, PPAR-γ, VEGF, and ET-1, are involved in ovarian fibrogenesis. Ovarian fibrogenesis is associated with various ovarian diseases, including ovarian chocolate cyst, PCOS, and premature ovarian failure. One finding of particular interest is that fibrogenesis in peripheral tissues around an ovarian chocolate cyst commonly causes ovarian function diminution, and therefore, this medical problem should arouse widespread concern in clinicians worldwide.
CONCLUSIONSPatients with ovarian fibrosis are susceptible to infertility and tend to have decreased responses to assisted fertility treatment. Thus, protection of ovarian function should be a priority for women who wish to reproduce when making therapeutic decisions about ovarian fibrosis-related diseases.

BACKGROUND:
Polycystic ovary syndrome (PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women's physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews (SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed.
OBJECTIVE:
To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS, as well as to assess the quality and risks of bias of the available SRs.
SEARCH STRATEGY:
Nine electronic databases (Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, Chinese National Knowledge Infrastructure, Wanfang Data, Chongqing VIP Chinese Science and Technology Periodical Database, and China Biology Medicine disc) were searched from their establishment to July 27, 2022. Based on the principle of combining subject words with text words, the search strategy was constructed around search terms for "acupuncture," "polycystic ovary syndrome," and "systematic review."
INCLUSION CRITERIA:
SRs of randomized controlled trials that explored the efficacy and (or) safety of acupuncture for treating patients with PCOS were included.
DATA EXTRACTION AND ANALYSIS:
Two authors independently extracted study data according to a predesigned form. Tools for evaluating the methodological quality, risk of bias, reporting quality, and confidence in study outcomes, including A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-analyses for Acupuncture (PRISMA-A), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), were used to score the included SRs.
RESULTS:
A total of 885 studies were retrieved, and 11 eligible SRs were finally included in this review. The methodological quality of 2 SRs (18.18%) was low, while the other 9 SRs (81.82%) were scored as extremely low. Four SRs (36.36%) were considered to be of low risk of bias. As for reporting quality, the reporting completeness of 9 SRs (81.82%) was more than 70%. Concerning the confidence in study results, 2 study results were considered to have a high quality of evidence (3.13%), 14 (21.88%) a "moderate" quality, 28 (43.75%) a "low" quality, and 20 (31.24%) considered a "very low" quality. Descriptive analyses suggested that combining acupuncture with other medicines can effectively improve the clinical pregnancy rate (CPR) and ovulation rate, and reduce luteinizing hormone/follicle-stimulating hormone ratio, homeostasis model assessment of insulin resistance, and body mass index (BMI). When compared with medicine alone, acupuncture alone also can improve CPR. Further, when compared with no intervention, acupuncture had a better effect in promoting the recovery of menstrual cycle and reducing BMI. Acupuncture was reported to cause no adverse events or some adverse events without serious harm.
CONCLUSION
The efficacy and safety of acupuncture for PCOS remains uncertain due to the limitations and inconsistencies of current evidence. More high-quality studies are needed to support the use of acupuncture in PCOS.

4.Potential use of durian fruit (Durio zibenthinus Linn) as an adjunct to treat infertility in polycystic ovarian syndrome.
Journal of Integrative Medicine 2016;14(1):22-28
Infertility due to polycystic ovarian syndrome (PCOS) is a worldwide problem that is increasing at alarming rates. Insulin resistance, the prime factor of PCOS, induces comorbid metabolic syndrome as well. Durian (Durio zibenthinus Linn), a fruit of Southeast Asia, is used as a natural supplement in healthy diets. This paper is a short literature review that examines the fruit's effects against various components of metabolic syndrome and its fertility-enhancing properties in PCOS. Various published literature was reviewed to learn of the anti-inflammatory, anti-oxidant, anti-obesity, anticholesterol, and antihypoglycaemic nature of the fruit. The literature search was done using PubMed, Google Scholar and library databases. The keywords used were polycystic ovarian syndrome, infertility, metabolic syndrome and Durian zibenthinus Linn. Reviewed studies showed that the fruit is effective against various components of metabolic syndrome, but the mechanisms of action against anovulation and menstrual disturbances in PCOS have yet to be studied. The traditional use of durian as a fertility-enhancing agent needs to be validated scientifically by isolating its various components and ascertaining its fertility enhancing properties.

BACKGROUNDEndometriosis affects natural fertility through various approaches, and in vitro fertilization (IVF) is a good treatment. But the IVF result of endometriosis patients is still under debate. We investigated the effect of endometriosis on IVF by analyzing the data from a single reproductive center.
METHODSA retrospective, database-searched cohort study was performed. Relevant information was collected from the electronic records of women who underwent IVF/intracytoplasmic sperm injection between January 2006 and December 2010 in the Assisted Reproductive Unit of Sir Run Run Shaw Hospital. Patients with endometriosis were enrolled the study group. The rest of the women formed the control group. The main outcome was the clinical pregnancy rate. Secondary outcomes were oocytes retrieved number, fertilization rate, high-quality embryo rate, number of high-quality embryo for embryo transplantation, and implantation embryo/high-quality embryo ratio (IE/HQE ratio). Comparisons were performed by the c(2)-test and independent t-test.
RESULTSThe endometriosis group (n = 177) had a markedly lower oocytes retrieved number, fertilization rate, implantation rate, and clinical pregnancy rate (7.6 ± 5.1, 63.6%, 27.7%, and 45.2%, respectively) compared with the non-endometriosis group (n = 4267; 11.8 ± 7.3, 68.4%, 36.2%, and 55.2%, respectively). Stratified analysis showed that this difference was found in the subgroup younger than 35-years old, while only fertilization rate and implantation rate were different in the elder subgroup. The ratio of high-quality embryos transferred is lower in endometriosis group (53.7% vs. 71.8%, P < 0.05), but there is no difference in IE/HQE ratio between two groups. There is no significant difference in fertilization rate, implantation rate, and clinical pregnancy rate between mild and severe endometriosis patients.
CONCLUSIONSEndometriosis patients suffer a decreasing IVF pregnancy rates mainly caused by reducing oocytes number and fertilization rate, regardless of the severity of the disease. Appropriate intracytoplasmic sperm injection manipulation might improve the outcomes of IVF.

OBJECTIVETo analyze the possible causes of total fertilization failure (TFF) in conventional in vitro fertilization (IVF).
METHODSWe included in this study 552 couples who accomplished the first conventional IVF cycle in our center from January 2007 to August 2008. All the males met the Kruger/Tygerberg criteria, with the teratozoospermia rate < 96% in the previous 12 months and the postwash motile sperm > 1 million on the day of egg retrieval. The eggs were fertilized totally by conventional IVF.
RESULTSOf the total number, 515 couples got zygotes by conventional IVF, with a fertilization rate of 78.67%, and 37 suffered TFF. The rates of primary infertility and teratozoospermia were significantly higher in the TFF group than in the fertilized group (P < 0.05). There were no statistically significant differences between the two groups in the number of controlled ovarian hyperstimulation (COH) days, the number of oocytes retrieved, the dose of gonadotropin (Gn) used, the age of the couples, the length of protocols and the rate of oligoasthenozoospermia.
CONCLUSIONIntracytoplasmic sperm injection (ICSI) can be considered for at least some of the oocytes to avoid unnecessary fertilization failure in teratozoospermia patients by Kruger/Tygerberg strict criteria.

9.Relationship between mycoplasma infection and germ cell sulfogalactosylglycerolipid.
National Journal of Andrology 2004;10(3):215-221
It is well known that mycoplasma can cause infection in the male reproductive tract. Some studies indicate that Ureaplasma urealyticum (Uu), a species of mycoplasma, is associated with male infertility. Sulfogalactosylglycerolipid(SGG) is the major mammalian male germ cell glycolipid, synthesized via sulfation of galactosylglycerolipid in early primary spermatocytes. Some experiments have proved that SGG is implicated in sperm-egg binding by linking arylsulfatase A (AS-A), SGG's ligand on the egg. SGG can be desulfated by binding mycoplasmas and transformed galactosylglycerolipid, which doesn't bind AS-A. So the binding and degradation of the sperm SGG by mycoplasmas may play a role in the induction of male infertility. As a kind of mycoplasma, Uu can also bind SGG, which offers another explantion for the association of Uu infection with male infertility caused by Uu infection.

10.Intracytoplasmic sperm injection for Klinefelter patients and the risk of chromosome anomaly in the patients' offspring.
National Journal of Andrology 2005;11(2):149-151
Patients with Klinefelter's syndrome are generally characterized by a 47, XXY karyotype, seminiferous tubule dysgenesis, azoospermia and infertility. However, focal spermatogenesis and severe oligozoospermia have been found in a few cases of 47, XXY, too. With the recent development in assisted reproductive technologies, the recovered spermatozoa by testicular biopsy from Klinefelter patients have been used for intracytoplasmic sperm injection (ICSI) and over 30 healthy neonates have been born. The conception of one 47, XXY fetus was found and then underwent abortion. This review focuses on the ICSI treatment of infertility in Klinefelter patients and the risk of chromosome anomaly in the offspring of these patients.
