Conditions

Frozen Embryo Transfer

Brief summary

The study focus on the impact of estrogen/progesterone substitution during artificial cycle frozen embryo transfer (AC-FET) in women undertaking assisted reproductive technology treatment (ART).

Detailed description

The aim is to investigate whether the coagulation is activated in women undergoing estrogen/progesterone substitution during artificial cycle frozen embryo transfer (AC-FET) in assisted reproductive technology treatment (ART). An activation of the coagulation might induce an increased thromboembolic risk in these women. Thus, the present study may lead to improvement of the current treatment protocol for women receiving AC-FET and ultimately prevent thromboembolic complications for woman in fertility treatment.
