Active clinical trials for "Infertility"

This is a Single-centre pilot study, randomized, controlled open-label trial with the aim to assess the clinical pregnancy rate and the early pregnancy loss rate between two different schemas for frozen embryo transfer cycles stimulated with HRT. Furthermore, the investigators would like to evaluate the predictivity of pregnancy and early miscarriage by looking at the endocrinological profile (estradiol and progesterone levels) within the endometrial preparation and the day of embryo transfer (ET).

This study is intended for women undergoing their first cycle of 3 intrauterine inseminations. All 3 inseminations will be personalized by using algorithms to determine the dose of study medication.

Men with infertility and normal hormone levels have few options for fertility treatment. Previous research suggests that men with infertility may have low levels of the active form of Vitamin A, called retinoic acid, in their testes. In a pilot study of 20 men with low numbers of sperm (<10 million motile sperm), roughly half the men showed improvement in sperm production. Thus, we want to see if retinoic acid administration to men with azoospermia (no sperm present) can initiate sperm production.

The aim of the study is to evaluate the effect of antioxidants on IVF outcome in infertile patients undergoing IVF who are expected to produce low number of eggs compared to a control group. The investigators assumed that the conception rate is higher in those patients taking some antioxidants supplementation. The patients will be given antioxidant drug one month before starting IVF trial once daily by mouth. Uniform protocol of stimulation will be done during the cycle by a type of short protocols known as the antagonist protocol. Egg retrieval will be done under anesthesia. pregnancy test will be done 2 weeks after embryo transfer. The investigators will also assess the number and quality of eggs on the day of egg pick up. In addition, the researchers will assess the number of first and second grade embryos that are put on the day of embryo transfer.

The primary objective of this study is to confirm the efficacy of a single oral 900mg dose of nolasiban to increase the ongoing clinical pregnancy rate at 10 weeks post embryo transfer (ET) day.

To compare the acceptance, safety, and efficacy of needle-free jet anaesthetic technique (MadaJet) versus needle injection for sperm retrieval in patients with azoospermia.

The current study aims to test the efficacy a mindfulness based intervention for women facing fertility problems - the Mindfulness Based Program for Infertility (MBPI). MBPI comprises 10 weekly group sessions of approximately 2 hours each, run in small groups of 10-15 women. The main goal of MBPI intervention is to reduce depressive and anxiety symptoms and promote infertility self-efficacy and acceptance and mindfulness skills. The MBPI is intended to develop willingness/acceptance through a process of contacting the present moment and be in touch with the unfolding experience in an open and non-judgmental way, particularly infertility-related experiences.

The objective of this study is to assess the effectiveness of adjuvant growth hormone injection during controlled ovarian stimulation, in poor responder women undergoing intracytoplasmic sperm injection (ICSI) procedures.

A male factor is responsible for almost half the cases of subfertility. Varicocele is a major cause of impaired spermatogenesis and potentially a correctable cause. It affects up to 40% of men with primary subfertility and 80% of men with secondary subfertility. Varicocelectomy is now accepted as a cost effective treatment in subfertile men with clinically palpable varicocele and impaired semen parameters. Recently, Varicocelectomy is reported to improve fertility potential in patients with severe oligozoospermia. In one such study, Varicocelectomy was associated with a statistically significant increase in sperm density and motility. Spontaneous pregnancy was achieved in16.7% of cases. In a recent meta-analysis, Varicocelectomy in men with severe oligozoospermia showed a strong trend toward improvement in pregnancy rate (PR) [OR= 1.69, 95% CI (0.951, 3.020), p= 0.073] and statistically significant increase in live birth rate (LBR)[OR=1.699, 95%CI (1.020, 2.831), p= 0.04]. The impact of ligation of internal spermatic artery (ISA) during Varicocelectomy is a matter of debate. Conventional view is arterial ligation can negatively affect testicular function and decrease the likelihood of post-operative paternity. Other investigators reported that ligation of ISA was not associated with significant changes in postoperative semen parameters, testicular size or PR in comparison to artery preservation. Moreover, laparoscopic artery-ligating Varicocelectomy was proved to be superior in the form of shorter operative time and lower recurrence rates with no difference in semen parameters or PR in comparison to laparoscopic artery-preservation varicocelectomy. Also, isolation of ISA is not an easy task during subinguinal Varicocelectomy due to compression by external oblique aponeurosis and its inherent anatomical variation. In 29 % and 57% of the cases, the ISA is surrounded by the varicose vessels and adherent to the veins respectively. Thus, the ISA is liable to a substantial risk of accidental ligation during subinguinal Varicocelectomy. Whether or not ligation of the ISA has a deleterious effect on the fertility outcomes in patients with severe oligozoospermia; this is not clear in the literature. This prospective randomized study was conducted to assess the impact of ISA ligation during subinguinal Varicocelectomy on fertility outcome in patients with severe oligozoospermia.

This study is for evaluating safety and efficacy of Recombinant human follicle-stimulating hormone (Follitrope) injection compared with Gonal-F® Pen undergoing controlled ovarian hyper stimulation in vitro fertilization - embryo transfer (IVF-ET) in China
