The aim of this work was to evaluate the relationship between follicular size at the time of oocyte retrieval, and the subsequent oocyte competence to be fertilized and to develop in vitro. All the obtained oocytes were classified according to the corresponding volume of aspirated follicular fluid. Aspirated volume of follicular fluid <2 ml corresponded to a follicular diameter <16 mm and const...

BACKGROUND The aim of this study was to determine whether, in polycystic ovarian syndrome (PCOS) patients, HCG action prolonged for 4 h improves the action of angiogenic substances [ovarian renin angiotensin system and vascular endothelial growth factor (VEGF)], and consequently follicular maturation, oocyte quality and oocyte fertilization competence. METHODS In this prospective study 20 pat...

OBJECTIVE To compare cryopreservation of mature human oocytes with slow-rate freezing and vitrification and determine which is most efficient at establishing a pregnancy. DESIGN Prospective randomized. SETTING Academically affiliated, private fertility center. PATIENT(S) Consenting patients with concerns about embryo cryopreservation and more than nine mature oocytes at retrieval were ran...

The treatment of infertility has developed rapidly, and the anaesthetist may be involved in many aspects of the patient’s treatment, which may be complex. The harvesting of oocytes needs to take place within a defined period of time, or ovulation may have occurred and oocytes will be lost. Couples presenting for infertility treatment are generally anxious and often the women are emotional at th...

BACKGROUND Serum progesterone has been advocated as a tool in the diagnosis of early pregnancy failure. We conducted this prospective study in order to investigate the potential value of early (14 days after oocyte recovery) serum progesterone measurement, in women undergoing IVF/ICSI and receiving rectal progesterone supplements, in relation to pregnancy outcome. METHODS 442 women consecutiv...

To determine if blastocyst trophectoderm biopsy for PGT-A is associated with an increased rate of live birth per embryo in good prognosis IVF patients at a single center. We performed retrospective cohort study undergoing transfer cycles center from 1/1/2017 through 12/31/2019. evaluated the transferred and without two groups patients: using embryos donor oocytes autologous less than 35 years o...

background: there has been an increase in number of obese infertile females booked for advanced infertility treatment procedures like in vitro fertilization (ivf) and intra cytoplasmic sperm injection (icsi). the knowledge of impact of body mass index (bmi) on reproductive outcome can help to counsel these patients. objective: to compare reproductive outcome in females of different bmi after ic...

OBJECTIVE To evaluate human oocyte ability to undergo fertilization and subsequent preimplantation embryonic development in relation to a wide panel of follicular fluid (FF) arachidonic acid derivatives (AAD) and linoleic acid derivatives (LAD) of prospectively selected patients undergoing intracytoplasmic sperm injection (ICSI). METHODOLOGY Study was designed as a two center (a university cl...
