Active clinical trials for "Infertility"

The purpose of this study is to determine whether in Assisted Reproductive Technologies the use of culture medium supplemented with G-CSF, a growth factor working on stem cells, may improve the embryo implantation and pregnancy rate in infertile patients undergoing IVF cycles.

Nowadays, one in six couples consults for fertility problems. If the standard examination and tests do not reveal any cause of infertility, the woman may undergo a laparoscopic exploration which reveals endometriosis in more than 50% of cases. Endometriosis is an inflammatory disease defined as the presence of endometrial tissue out of the uterine cavity. It is frequent (1 in 10 women) and associated with a high economic burden (22 billion dollars in 2002 in the USA) and important decrease in quality of life. Physiopathological mechanisms and risk factors for endometriosis are not well identified. A woman with endometriosis is 20 times more at risk of infertility. Fecundity rate of a 25-year-old couple is about 15 to 20% in the general population and only 2 to 10% in case of endometriosis. There are many manifestations of this disease (infertility, pelvic pain) and the anatomo-clinical correlation is not good. The presently used international classification (American Fertility Society revised in 1985, AFSr) does not predict the chance of pregnancy. New scores such as the Endometriosis Fertility Index (EFI) have been proposed to do so, but need to be validated. Treatment for endometriosis-related infertility is not consensual. A prospective cohort study would give access to clinical data of patients followed in our center, so as to identify clinical factors predicting pregnancy and to help treatment decision for women with endometriosis suffering from infertility.

100mg clomiphene citrate used for ovulation induction. The investigators take blood sample at 3 and 10 days of menstruation and count AMH and inhibin B.

Our study is observational, we are observing data from routine measurements during IVF/ICSI. Our study does not assess IVF/ICSI as an intervention, we are evaluating the role of FSI and preovulatory count which are calculated by observing routine measurements during the IVF/ICSI procedure. 300 women with polycystic ovarian syndrome (PCOS) who are decided to be treated with ICSI. will be subjected to full history taking and clinical examination. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by follicle stimulating hormone (FSH) stimulation until the day of Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. Follicular output rate (FORT) will be calculated as: (FSI =PFC*10000/AFC*Total dose of FSH). FORT correlation to pregnancy will be compared to that of the preovulatory count number

Embryo culture is a cornerstone of in vitro fertilization treatments. Usually, embryos are cultured in microdrops of culture media in incubators with controlled temperature, humidity and atmosphere. However, these culture systems are static, while in vivo the initial growth of the embryo takes place in the uterine tube and they are submitted to a dynamic environment. The aim of this study is to compare the embryo development on days 2 and 3 of culture morphological features of embryos under static and dynamic(microfluidics) systems of culture.

RATIONALE: Treatment for pediatric extracranial germ cell tumors may cause side effects and secondary cancers later in life. A study that evaluates patients after receiving combination chemotherapy or surgery may help doctors understand the side effects and secondary cancers that occur later in life. PURPOSE: This study is looking at treatment outcome and quality of life in patients with pediatric extracranial germ cell tumors previously treated on clinical trial CCLG-GC-1979-01 or CCLG-GC-1989-01.

The relation between the timing of COC denudation and oocyte /embryo quality is controversial. The aim of this study is to examine whether timing of denudation of sibling oocytes has any effect on embryo quality.

The nuclear lamina (LN) consists of a network of proteins interposed between the chromatin and the internal nucleic membrane, to which it is closely associated. LN consists essentially of lamins encoded by the LMNA (Lamines A / C), LMNB1 and LMNB2 genes (BI, B2, B3 lamins). Malfunctions of the A / C-type laminates causing the production of a toxic isoform called progerin are directly responsible for various serious pathologies such as Progeria Hutchingson-Gilford. This rare disease is characterized by accelerated pathological aging. Moreover, it is known that progerin is produced in the absence of any mutation of the gene LMNA is involved in the physiological aging of tissus. The ovarian reserve of a woman is a parameter that changes with age. Although this progressive loss is inevitable in the course of life, the kinetics of this ovarian exhaustion appear variable according to the women, sometimes leading to an accelerated loss causing a discordance between the female age and the ovarian age. But ovarian age becomes a major prognostic parameter to be taken into account during any attempt at medical assistance to procreation (AMP) and is often incriminated in the failures of MPAs. There are currently few markers to predict the quality of ovarian response of women to ovarian stimulation, let alone the quality of the oocytes retrieved. However, their quality directly influences their ability to give an evolving embryo and therefore a pregnancy Our team has previously shown that type B laminates are involved in human spermiogenesis, and highlighted the human B3 isoform. These very encouraging results obtained on human spermatogenesis, have prompted us to also look at the potential interest of the exploration of the nuclear lamina within the human ovary. The aim of this project is therefore to continue the exploration of the nuclear lamina and its potential role on the quality of human gametes, by studying the follicular ovarian cells surrounding the oocyte. These cells express A / C type lamins and sometime progerin Investigators want to conduct a prospective pilot study in a cohort of 40 women in MPA, aged between 20 and 42 years. The main objective is to compare the levels of expression of the A / C, B and progerin laminae in the follicular cells of 2 groups of women: a group of infertile patients managed to induce ovulation in order to Intraconjugal AMP and a group of women managed to induce ovulation to give their oocytes. For this purpose, investigators will analyze the expression of the A / C and B lamins in RT-PCR, the localization of the lamins and progerin in immunofluorescence, and will look for quantitative variations in the production of A / C and / or progerin lamins by western- blot, depending on the age of the patients. This pilot study will allow investigators to characterize for the first time the LN of human follicular cells. They should highlight variations in the expression and / or localization of lamins and possibly progerin in patients tested according to their age and / or ovarian reserve. The team preliminary results showed that this track deserves to be explored. This is an excellent opportunity to bring new insights into the understanding of the mechanisms responsible for alteration of ovarian reserve in women and the prognosis of MPA attempts. Finally, this approach could serve as a basis for a larger, multicenter study. These markers could represent new diagnostic markers to be taken into account to evaluate the chances of pregnancy of each woman in AMP.

The aim of the present study is to evaluate the impact of hysteroscopy prior to starting the IVF (in vitro fertilisation) cycle on treatment outcome in women with unexplained primary infertility.

The purpose of this trial is to evaluate the morphological characteristics of the uterus with three-dimensional ultrasound (3DUS) at the time of IVF/ICSI treatment and correlate it to clinical outcomes. The uterus will be assessed in the 3D coronal plane and measurements will be performed to assess whether they correlate with clinical pregnancy rate, miscarriage rate and live birth rate.
