Leukocyte origin and profile in follicular aspirates at oocyte retrieval.
BACKGROUND Follicular aspirates represent a snapshot in time of conditions within the follicle at oocyte retrieval in women undergoing in vitro fertilization and embryo transfer. This clinical material has been much investigated and yet its cellular composition remains unclear. In this study we investigated the origin and profile of leukocytes found within follicular aspirates. METHODS We per...
متن کاملFollicular flushing during oocyte retrieval in assisted reproductive techniques.
BACKGROUND Ultrasound guided transvaginal aspiration of oocytes has replaced other methods of oocyte retrieval for in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). However, there is controversy over whether flushing yields a larger number of oocytes and a higher potential for pregnancy than aspiration only. OBJECTIVES To determine whether follicular aspiration and flu...
متن کاملConventional start Late follicular phase start Luteal phase start Initial visit Oocyte retrieval Initial visit Oocyte retrieval
Recent findings In random-start protocols, the number of total and mature oocytes retrieved, oocyte maturity rate, mature oocyte yield and fertilization rates are similar to those in conventional (early follicular phase start) protocols. Starting ovarian stimulation in the late follicular or luteal phase did not show any superiority against the other. The presence of corpus luteum or luteal pha...
متن کاملFollicular Development and Oocyte Growth
Follicular development begins as early as the fourth month of fetal life [1]. At that time, the primordial germ cells (PGCs) have migrated from the yolk sac endoderm to the gonadal ridge, undergoing mitotic divisions. PGCs are called oogonia once they reach the gonads, then the oogonia enter the first meiotic division and become primary oocytes. Somatic cells originating from the primitive gona...
متن کاملO-10: Assessment of Oocyte and Embryo Quality in Different Time between Oocyte Retrieval and hCG Priming
Background: Abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. In this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hCG) administration. Materials and Methods: A total of 985 metaphase II were ...
