Active clinical trials for "Infertility"

The purpose of this study is to assess whether the probability of pregnancy is dependent on the duration of GnRH agonist downregulation in IVF cycles.

The purpose of this study is to investigate the effect of G-CSF on endometrial thickness in women who have failed reaching minimal endometrial thickness by standard treatments, to assess how many reach embryo transfer and what implantation and pregnancy rates are in comparison to control patients. The study will be conducted in women undergoing transfer of previously cryopreserved embryos or undergoing transfer of embryos from donor eggs.

Pregnancy is a unique period which requires alterations in the immune system to allow for tolerance of a haploidentical fetus. The goal of this study is to measure maternal blood levels of proteins known to promote immune tolerance in early implantation and pregnancy to look for associations between tolerance, miscarriage and failed embryo transfer. Establishing predictive factors of miscarriage and failed in vitro fertilization could have implications for a large portion of couples and serve to guide current and future family planning efforts.

Studying the possible outcome differences between surgery or medical treatment with ulipristalacetate (UPA) solely before 'in-vitro fertilisation/intracytoplasmic sperm injection' (IVF/ICSI) treatment in infertile couples.

Stimulation protocols for IVF underwent several cycles of upgrading aiming to achieve reasonable outcomes with low-cost cycles. Antagonist protocols have been introduced as effective and comparable to long agonist regarding the outcomes. However, these protocols are still costly. Alternative protocols using progestin suppressions appear options for consideration.

The study to compare to the efficacy and safety of Crinone versus combination medication in infertile women receive frozen-thawed embryo transfer (FET) in artificial cycles (AC).

All patients starting an IVF-treatment at the clinics, and meeting the inclusion criteria, will be offered to participate in the study. Randomization will be performed on day 5 and the patients will be allocated into either morphology only group or time-lapse group. Embryos will be cultured to day five according to the clinics own routines. All embryos in both groups will be cultured using time-lapse incubation. In the control group the embryo selection will be based only on traditional morphological evaluation and in the treatment group a time-lapse selection model (KID Score day 5) will be used to select the embryo.

To evaluate the effect of oestradiol pre-treatment in a combined ultrashort flare GnRH agonist /GnRH antagonist protocol

This Clinical Study has been designed to assess and compare the impact of in vitro or in vivo culture conditions on the euploidy of sibling blastocysts.

Overweight/obesity is associated with sub-fertility. The investigators will assess if regular exercise training prior to assisted fertilization will improve pregnancy rate in overweight/obese women referred to assisted fertilization. It is expected that training will be successful in increasing pregnancy rate
