Luteal phase ovarian stimulation
Ovarian stimulation may safely and effectively be initiated in the luteal phase without compromising oocyte number or quality.
Luteal phase ovarian stimulation v. RANDOM START IN CANCER PATIENTS v. DUAL/DOUBLE STIMULATION IN ART v. SEGMENTATION OF THE CYCLE
RANDOM START IN CANCER PATIENTS
RANDOM START IN CANCER PATIENTS Random-start ovarian stimulation provides a significant advantage by decreasing total time for the IVF cycle, and in emergent settings, ovarian settings stimulation can be started at a random cycle date for the purpose of fertility preservation without compromising oocyte yield and maturity.

Progesterone and embryo quality
This study retrospectively enrolled 4, 236 fresh in vitro 4, 236 fertilization (IVF) cycles Elevated progesterone levels (>2. 0 ng/ml) before oocyte maturation were consistently detrimental to the oocyte.
Progesterone and embryo quality
986 Gn. RH antagonist IVF/ICSI cycles Progesterone levels at induction showed an inverse relation with top quality blastocyst formation ROC curve analysis identified P level >1. 49 ng/ml as the best cut-off for identification of patients at risk for the absence of top quality blastocysts

…. Tailored dose KEY MESSAGE: The FSH starting dose may be selected according to patient’s age, AMH and FSH. This strategy increased the proportion of patients with an optimal response The possible effects of this approach on pregnancy and livebirth rates needs further investigation.
OPTIMIST TRIAL
OPTIMIST TRIAL
OPTIMIST TRIAL Q/ Is there a difference in live birth rate and/or cost-effectiveness between antral follicle count (AFC)-based individualized FSH dosing or standard FSH dosing in women starting IVF or ICSI treatment? A/ In women initiating IVF/ICSI, AFC-based individualized FSH dosing does not improve live birth rates or reduce costs as compared to a standard FSH dose.

ADJUVANT THERAPIES • Aspirin • Adjuvant therapies • Antibiotic
Aspirin “Currently there is no evidence in favour of routine use of aspirin in order to improve pregnancy rates for a general IVF population. This is based on available data from randomised controlled trials, where there is currently no evidence of an effect of aspirin on women undergoing ART, as there is no single outcome measure demonstrating a benefit with its use. Furthermore, current evidence does not exclude the possibility of adverse effects. ”
Combined adjuvant therapy “The present study adds further to published research that adjuvantia, either used alone or in combination, are unlikely to improve live birth rates. Of even greater concern is that the adjuvant combinations used in this study may be detrimental in IVF cycles using frozen embryos”
Antibiotic “For transvaginal procedures like oocyte retrieval, antibiotic prophylaxis is recommended in patients with a history of endometriosis, PID, ruptured appendicitis, or multiple prior pelvic surgeries. ”
