Impact of embryo quality and endometrial thickness on implantation in natural cycle IVF.

Purpose: The aim of this study is to assess the effect of the endometrial thickness and embryo quality on the implantation potential in natural cycle IVF (NC-IVF).

FERTILITY PRESERVATION IN YOUNG WOMEN WITH EARLY-STAGE BREAST CANCER.

Although breast cancer (BC) occurs more often in older women, it is the most commonly diagnosed malignancy in women of childbearing age. Owing to the overall advancement of modern medicine and the growing global trend of delaying childbirth until later age, we find ever more younger women diagnosed and treated for BC who have not yet completed their family. Therefore, fertility preservation has emerged as a very important quality of life issue for young BC survivors.

Importance of ovarian tissue cryopreservation in fertility preservation and anti-aging treatment.

Various oncological and non-oncological diseases, as well as their treatments, can cause premature ovarian insufficiency and reduce a woman's reproductive potential. Fertility preservation is, therefore, becoming an emerging field of reproductive medicine allowing these patients to have their own biological children. The aim of this review is to analyze the importance of ovarian tissue cryopreservation as a fertility preservation method as well as its new role as a hormone replacement treatment.

The role of luteal support during IVF: a qualitative systematic review.

The aim of this review is to provide qualitative evidence-based synthesis regarding efficacy of luteal-phase support on fertility outcome in women undergoing fertilization (IVF) with respect to clinical or live birth rates and pregnancy loss rates. Although the need of luteal phase support in IVF/ICSI cycles is well-known, the optimal start, dosage, route and the duration of the luteal phase support is still subject of debate. Data suggest that the optimal period to start with the luteal phase support would be between 24-72 hours after oocyte-retrieval and should continue at least until a positive pregnancy test is achieved.
