Background: The objective was to compare the use of micronized vaginal progesterone 800 mg daily and oral dydrogesterone 40 in endometrial preparation for frozen-thawed embryo transfer (FET). Methods: Prospective randomized study with women undergoing FET along hormone replacement therapy preparation, between September 2019 February 2021. A total 73 patients were randomly selected orally receiv...

BACKGROUND Cryopreservation of embryos has been an usual component of clinic in assisted reproductive technology (ART) programs. Recently the dramatic increase in cryobiology activity in the clinical centers has enhanced methods of freezing and improved vitrification protocols are being developed. OBJECTIVE The aim of our study was to assess the effect of storage duration of frozen embryo on ...

During the last decades, many studies have shown the possible influence of sperm DNA fragmentation on assisted reproductive technique outcomes. However, little is known about the impact of sperm DNA fragmentation on the clinical outcome of frozen-thawed embryo transfer (FET) from cycles of conventional in vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). In the present stu...

To investigate the effects of the frozen embryo transplantation for patients with poor outcome of endometrial growth by using growth hormone intrauterine perfusion combined with replacement cycle in the treatment of non-response thin endometrium. This is a prospective study and study participants were consecutively recruited between Jun 2014 and December 2014. A total of 5 non-response thin end...

OBJECTIVE To assess the usefulness of the vitrification method in clinical practice. DESIGN Clinical study of vitrification of human oocytes. SETTING A university-affiliated hospital. PATIENT(S) Thirty-four patients who agreed to undergo additional IVF-ET after the failed fresh cycle using the previously vitrified/thawed oocytes. INTERVENTION(S) Surplus oocytes from the IVF-ET patients ...

Objective. To optimise the use of freeze/thaw testicular immotile spermatozoa from nonobstructive azoospermia patients and to analyse the outcome of intracytoplasmic sperm injection (ICSI) of such spermatozoa. Methods. Testicular specimens were retrieved and cryopreserved from forty patients with nonobstructive azoospermia and underwent one cycle with thawed spermatozoa (Group I) that led to pr...

OBJECTIVE To document outcomes of oocyte cryopreservation performed as a routine procedure in an IVF program. DESIGN Describing the rate of oocyte survival, embryo transfer (ET), implantation, and live births of IVF-intracytoplasmic sperm injection performed on thawed oocytes. SETTING Reproductive medicine center in Italy. PATIENT(S) Women (n = 696) who failed to conceive after IVF-intrac...
