105 infertile women are enrolled in the randomized controlled trial: 70 women with a history of RIF with donated oocytes and 35 infertile women undergoing the first oocyte donation attempt. Women receiving donated oocytes are treated with progressively increasing doses of oral estradiol followed by intravaginal progesterone after previous pituitary desensitization with GnRH agonist. 35 RIF patients are treated with GH (GH patients) while the rest 35 RIF patients (non-GH patients) and 35 first-attempt patients (positive control group) are not.
To set up a Cooperative Network by enrolling 5000 patients with Adenomyosis(AM) from multiple centers.Based on the Network platform and Database,the investigators try to explore the diagnostic strategies for AM and carry out epidemiological survey on the semeiology of AM.In addiction，the investigators expect to conduct research on the effect and the follow-up fertility outcomes of different medical or surgical treatment, the etiology of AM and endometriosis,the perspective investigation of the malignant transformation of AM ;the high-risk factors of AM,and finally propel the formation of Expert Consensus and Clinical Guidelines about AM which suitable to chinese conditions.
50%-60% of the known causes of recurrent pregnancy loss(RPL) are associated with embryonic aneuploidy, such that preimplantation genetic screening (PGS) on embryos acquired by assisted reproductive treatment should improve the rate of pregnancy and live birth in those patients. In dispute though the clinical application of PGS has been, a series of studies show that the new generation of PGS(PGS 2.0), based on blastocyst biopsy followed by whole genome analysis, has significantly improved the clinical outcome of IVF treatment. At present, there is still a need for the evidence of the use of PGS 2.0 in RPL patients, who may benefit from this emerging technology considering the prevalence of genetic abnormalities and the number of transferable embryos in this population. An earlier single center RCT conducted by our IVF center displayed higher implantation rate, clinical pregnancy rate and ongoing pregnancy rate calculated by per embryo transfer(ET) cycle in IVF/ICSI+PGS group compared with IVF/ICSI group. This multi-center prospective randomized clinical trial is to provide more data to determine whether the clinical outcomes are significantly improved per treatment cycle such that provide evidence for the application of PGS in RPL patients. Besides, risk factors of PGS outcome are to be analyzed from multi-center data to build a model for prediction of the possible outcomes of PGS and direction of the clinical choice.
Adequate growth of the endometrium is crucial for implantation. Accordingly, the pregnancy success rate of patients with a thin endometrium is low. Furthermore, there is a little information about the factors responsible for impaired endometrial growth in patients with a thin endometrium. The researches have revealed that nitric oxide (NO) release can cause relaxation of vascular smooth muscle through a cyclic guanyl monophosphate (cGMP)-mediated pathway. Sildenafil is a type 5-specific Phosphodiesterase inhibitor that augments the vasodilatory effects of NO on vascular smooth muscle by preventing the degradation of cGMP and could improve blood flow and endometrial thickness. This study is designed to evaluate the effect of vaginally administered sildenafil suppositories on IVF/ICSI outcome of infertile patients with repeated IVF/ICSI failures.
KN015,the active substance recombinant human Follicle Stimulating Hormone（FSH） Fc fusion protein, which belongs to the pharmaceutical class gonadotropins.KN015 is proposed for Assisted Reproductive Technology (ART) programs only. Its indication is Controlled Ovarian Stimulation （COS）in combination with a gonadotropin releasing hormone (GnRH) antagonist for the development of multiple follicles in women participating in an ART program. Due to its prolonged duration of FSH activity compared to conventional recombinant FSH (rFSH), a single subcutaneous injection of the recommended dose of KN015 may replace any daily rFSH preparation in a COS treatment cycle. This study is to evaluation of the safety, tolerability, pharmacokinetics and pharmacodynamics of KN015 in healthy Chinese female subjects.
Ray and colleagues define "unexplained infertility" as failure to achieve pregnancy when the semen analysis is normal, evidence for ovulation is present, and tubal patency has been established. The efficacy of treatment declines with increasing age and duration of infertility Infertility is a disease , defined by the failure to achieve a successful pregnancy after 12 months or more of appropriate, timed unprotected intercourse or therapeutic donor insemination, barber evaluation and treatment may be justified based on medical history and physical findings and is warranted after 6 months for women over age 35 years. In unexplained infertility abnormalities are likely to be present but not detected by current methods including semen analysis in the man, assessment of the state of ovulation, ovulation reserve and patency of uterine tubes in the woman. unexplained infertility is not a rare item of infertility. Approximately 15% of infertility couple will be diagnosed with unexplained infertility after their diagnostic workup Many researches studied the laparoscopic tubal factor like tubo-ovarian relation, tubal kinks and fimbrial pathology. But we need to scope on more tubal factors like fatty mesosalpinx , fimbria ovarica, methylene blue free spill and others
1,25-dihydroxy-vitamin D3 (1,25 (OH) 2D3) or calcitriol regulates plasma calcium and phosphate concentrations in the blood by stimulating intestinal absorption and renal reabsorption of calcium and phosphate. 1.25 (OH) 2D3 is formed by the renal 1α25OH vitamin D-hydroxylase (Cyp27b1) and inactivated by the renal 25-hydroxy vitamin D-24-hydroxylase (Cyp24). Unpublished studies in mice revealed an inhibitory effect of 1.25 (OH) 2D3 on embryo implanation. An excess of 1.25 (OH) 2D3 could therefore lead to female infertility. The excess of 1.25 (OH) 2D3 could result from uncritical vitamin D intake with insufficient negative feedback by FGF23 / Klotho. The aim of the study is to identify patients with an excess of 1.25 (OH) 2D3.
Polycystic ovary syndrome accounts for the vast majority of anovulatory symptoms and hyperandrogenism in women. The diagnosis of Polycystic ovary syndrome has life-long implications, with increased risk for infertility, metabolic syndrome, and type 2 diabetes mellitus, and possibly for cardiovascular disease and endometrial carcinoma. Polycystic ovary syndrome is diagnosed in adolescents with otherwise unexplained, persistent hyperandrogenic anovulatory symptoms that are inappropriate for age and stage of adolescence. It should be considered in any adolescent girl with a chief complaint of hirsutism, treatment-resistant acne, menstrual irregularity, acanthosis nigricans, and/or obesity
The hysteroscopy used was rigid continuous flow diagnostic hysteroscopy (Tuttligen, Karl Storz, Germany). It has a 30o panoramic optic which is 4mm in diameter and the diagnostic continuous flow outer sheath is 6.5 mm in diameter. The patient was placed in lithotomy position with the buttocks projecting slightly beyond the table edge. A reflex camera (Olympus) with an objective that has a focal length varies from f70 to f140 together with (Karl Storz) special zoom length, adapter to Hopkins telescope and a suitable cableware used with computer flash unit. The hysteroscopic picture which appeared through the optic, transmitted on the monitor by the camera which is fitted on the eyepiece of the optic where the panoramic diagnostic hysteroscopy could be informed with better visualization and accuracy. The light generator which is a metal halide automatic light source with a 150 watt lamp (model G71A,Circon ACMI, Germany) was switched on and the high cable was attached to the hysteroscope. Dilatation of the cervix was avoided whenever possible to avoid leakage of the medium into the vagina. The hysteroscope was then introduced into the external os and advanced under vision along the axis of cervical canal. Once the cavity was entered, an overview of the uterine cavity was performed. This was followed by systematic examination for fundus then tubal ostia on both sides then the uterine wall through slow rotatory movements of the telescope. Diagnostic laparoscopy was done in the proliferative phase of the menstrual cycle .The patients were placed in the dorsal lithotomy position to allow vaginal access for uterine manipulation; the legs positioned so that the thighs are slightly flexed no more than 90o from the plane of the abdomen. The patient was placed in the complete horizontal position, Veress needle was placed through the umbilicus and into the peritoneal cavity, the primary trocar with sleeve (5mm in diameter) was placed at a similar angle in to the Veress needle. Secondary trocars were used, 2 secondary trocars were placed. The trocars were placed laterally, approximately 8 cm from the midline and 8 cm above the pubic symphysis to avoid the epigastric, vessels which are 5.5 cm from the midline at this level. Then laparoscopic dye chromotubation was performed
