Artificial Endometrial Preparation for Frozen Thawed Embryo Transfer Applying Either Endometrin or Utrogestan

02:57 EDT 19th April 2014 | BioPortfolio

Summary

The transfer of frozen-thawed embryos can be performed in a natural ovulatory cycle or in a hormonally manipulated cycle with a comparable pregnancy rate of 15%-20% per ET. When a hormonally modulated ET cycle is scheduled,an artificial endometrial preparation is carried out using estrogen stimulation followed by a concomitant progesterone treatment. Two progestative drugs are currently used in conventional IVF treatment, Utrogetan and Endometrin. Although Endometrin has been be efficiently used to support the luteal phase after embryo transfer in IVF cycles, currently, there is no study that assess its efficacy for clinical use in frozen-thawed ET cycles. The present study aims to compare the outcome of frozen thawed ET cycles when either Endometrin or Utrogestan are used as the progestative substitution in an artificially prepared endometrium.

Medical and Biotech [MESH] Definitions

The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.

Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.

Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.

Steroidal compounds related to PROGESTERONE, the major mammalian progestational hormone. Progesterone congeners include important progesterone precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with progestational activities.

Thinly cut sections of frozen tissue specimens prepared with a cryostat or freezing microtome.
