Active clinical trials for "Infertility"

This study aims to predefine the threshold FSH doses during the early follicular phases in low- dose step-up ovulation induction cycles used to treat anticipated high responders by monitoring total testosterone and androstenedione blood levels. The blood levels of total testosterone and androstenedione levels will be measured in patients at the starting day and at every control day when vaginal sonographic folliculometries and blood estradiol measurements are made. Hence, we are aiming to define an early monitoring parameter by which we will be able to define a follicular response to treatment before estradiol rise or apparently selected follicular growth.

This study is intended to evaluate ovarian cells after being submitted do different in vitro fertilization protocols. The investigators will analyze hormones secretion and intracellular mechanisms of these cells comparing the GnRH agonist protocol and the GnRH antagonist protocol.

Over the last 20 years, cervical screening programs have had huge success in reducing cervical cancer rates. These programs have done this by screening women at risk of developing cancer with regular smear tests. Women with abnormal smears are followed up in colposcopy clinics, and where needed, cervical surgery is performed to remove pre-cancerous areas on the cervix. Surgery to the cervix can include LLETZ (Large loop excision of the transformation zone) treatment or cone biopsy. Many studies in the last few years have looked at the impact that this necessary surgery can have on the function of the cervix. These studies have mainly found an association between LLETZ treatment and an increased risk of preterm labour. There have been no large studies investigating the effect cervical surgery may have on fertility. The investigators would like to examine the impact that cervical surgery may have on a woman's future fertility. It has been postulated that cervical surgery may cause the cervix to close, preventing sperm getting through or that it may cause changes in the secretions of the cervix, secretions that are necessary for normal interaction with sperm. The investigators would like to send a questionnaire to women who have attended colposcopy. The investigators will ask these women a series of questions relating to fertility desires and divide the women in to two groups depending on whether the women needed cervical surgery for pre-cancerous lesions or not. Hypothesis: That cervical surgery has an impact on the function of the cervix and on fertility.

The purpose of this study is to investigate the impact of follicular flushing on fertilization rate in women undergoing IVF treatment

Anti Mullerian hormone (AMH) is gaining place as ovarian marker, chiefly in infertility assistance. Investigators explored its correlation with oocytes retrieval after long GnRH agonist protocol for stimulation, in younger and older infertile population. Methods: This prospective analysis compiled data of 66 females, receiving ICSI treatment from April 2016 to October 2017. Serum FSH, LH, Estadiol, AMH and antral follicle count were assessed. Outcomes were measured as good (5 to 19 oocytes) and bad responders.

Men are recruited to collect seminal plasma samples and serum samples from men with azoospermia, men receiving medical treatment of infertility and men attending semen analysis. MicroRNA (miRNA) and PiWi-interacting RNA (piRNA) are analyzed for all of the groups to find potential differences. Steroid hormones are analyzed by liquid chromatography-tandem mass spectrometry.

Approximately 100 males with idiopathic infertility and oligo- and/or astheno- and/or and/or teratozoospermia and fertile woman will take a Test dietary supplement (TDS), containing carnitine, vitamins and trace elements (active group) or carotene (control group) for 6 months (50 subjects in active and control groups). Before intake, and 2 and 4 months after the commencement of TDS, all males will have spermogram. After 6-month use of the TDS and during the 12th month of the study, couples will be screened for conception, pregnancy, and a newborn

This clinical study has been organised to help improve the embryo quality in couples having high rate of sperm showing apoptotic signs. For this, the investigators intend to use a procedure (MACS: magnetic-activated cell sorting) that allows the identification and the removal of the apoptotic sperm cells. This procedure will increase the chance of using non-apoptotic sperm during in vitro fertilization via Intracytoplasmic Sperm Injection (ICSI). By using this procedure the investigators aim to increase the rate of embryos with good quality for these particular couples.

The objective of our observational prospective study will be to compare, for women treated for infertility and included in a ICSI program, the implantation rate and delivery rate obtained after the transfer of a single blastocyst , chosen in a group of patients on the basis of the embryo morphology and in the other group on the basis of both embryo morphology and follicular fluid cytokines content. 100 IVF infertile patients , aged 32-39 years, with normal ovarian reserve, previously stimulated for their first cycle with standard short protocol (GnRH-Ant) and r-FSH alone, who have had a low ovarian response, Fort < 50% ( FORT Criteria, 2012; FORT= PFCX100/AFC), will be treated for the second cycle with standard short protocol (GnRH-Ant) and r-FSH plus r-LH , according to the standard established by our clinical practice. Patients will be part of one of the following groups: Group 1: single embryo transfer on day 5, according to standard embryo morphological criteria Group 2: single embryo transfer on day 5, chosen on the basis of both embryo morphological criteria and levels of cytokines measured in the individual FF.

The aim of this study is to demonstrate the value of music in outpatient hysteroscopy on patients' level of pain and satisfaction in primarily infertile patients.
