Comparison of the Euploid Rate of Blastocyst Between PPOS and GnRH Antagonist Protocol in Women With PCOS Undergoing PGT-A

This randomized trial aims to compare the euploid rate of blastocysts between PPOS (progestin-primed ovarian stimulation) and GnRH (gonadotrophin releasing hormone) antagonist protocols in patients with PCOS (polycystic ovary syndrome) undergoing PGT-A (preimplantation genetic testing for aneuploidy). Infertile women with PCOS will be recruited for study after explanation and counseling if they fulfill the inclusion criteria and do not have the exclusion criteria. Eligible women will be randomised into one of the two groups: Antagonist group: Women will receive antagonist once subcutaneously daily from day 6 of ovarian stimulation till the day of the ovulation trigger. PPOS group: Women will receive oral MPA (medroxyprogesterone acetate)10mg qd from Day 3 till the day of ovulation trigger. The primary outcome is the euploidy rate of blastocysts.

Astronaut Vision Issues in a Ground Analog Population: Polycystic Ovary Syndrome

The investigators have documented a genetic predisposition for some astronauts to develop ophthalmologic issues (e.g., choroidal folds, cotton wool spots, optic disc edema). Women with polycystic ovary syndrome (PCOS) have several characteristics similar to those described in astronauts, including: higher homocysteine concentrations, increased incidence of intracranial hypertension, increased retinal nerve fiber layer thickness, increased incidence of white matter hyperintensities on MRI, increased androgen concentrations (or androgen responses to space flight), and indices of altered carbohydrate metabolism. Women with PCOS have not been evaluated in detail regarding the occurrence of other anomalies observed in astronauts including choroidal folds, optic disc edema and cotton wool spots as well as changes in cycloplegic refraction, and optic nerve sheath diameter. While researchers have evaluated one-carbon metabolism pathway polymorphisms re: PCOS, and initial studies show an association with certain one-carbon polymorphisms, none have looked at the complete set of SNPs proposed here. This study will evaluate women with PCOS and/or idiopathic intracranial hypertension (IIH) to assess one-carbon biochemistry and genetics and their possible correlation with ophthalmologic findings. The investigators aim to clarify the relationship of one carbon metabolism and ophthalmic findings in astronauts and patients with PCOS and/or IIH.

Clinical Application of Serum Anti-Müllerian Hormone (AMH) Measurements

This study aims to assess the association of Anti-Müllerian hormone (AMH) with polycystic ovarian syndrome, premature ovarian insufficiency and fertility. The main objectives include the following: 1. To study the level of serum AMH in women with PCOS and to evaluate the utility of serum AMH in the diagnosis of PCOS. 2. To evaluate the level of serum AMH in women with POI and to evaluate the utility of serum AMH in the management of POI. 3. To evaluate the associations of basal AMH level with FSH level and AFC respectively for women undergoing ART treatment. 4. To determine the optimal regimen of gonadotropin for ovarian stimulation for women undergoing ART treatment. 5. To evaluate the predictive value of serum AMH in reproductive outcomes including oocyte quality, embryo quality, pregnancy loss, clinical pregnancy and live birth rate in women undergoing ART treatment.

Comparison of Clomid and Lezra With Lezra for Ovulation Induction in Clomid Resistant PCOS Case

Clomiphene citrate resistant i.e failure to ovulate after 6 cycles of ovulation induction effects 15-40% of patients with PCOS.Two treatment groups will be formed one recieving letrozole alone and another recieving CC and letrozole combined.Mature follicles and endometrial thickness will be checked by transvaginal ultrasound and results will be recorded.

Sitagliptin or BeiDouGen Capsule Improve the Pregnancy Outcome in Patients with PCOS

This study will be carried out under the guidance of professional doctor, patients with PCOS will be treated with Sitagliptin or BeiDouGen capsule or both two to assess their ovarian function and reproductive outcomes, and compare the effect of different treatment methods, which will provide the basis for PCOS intervention strategy and related research

Genetics of Reproductive Disorders (Including Kallmann Syndrome) and Cleft Lip and/or Palate

The purpose of this study is to explore the genetic basis of reproductive disorders and cleft lip and/or palate.
