Specific protocols of controlled ovarian stimulation for oocyte cryopreservation in breast cancer patients
(2018-12-01)
Background Fertility preservation is an important concern in breast cancer patients. In the present investigation, we set out to create a specific protocol of controlled ovarian stimulation (cos) for oocyte cryopreservation ...
How effective are the non-conventional ovarian stimulation protocols in ART? A systematic review and meta-analysis
(Springer/Plenum Publishers, 2020-11)
Purpose: To compare the effectiveness of starting the ovarian stimulation on the early follicular phase (“Conventional”) with the newer range of non-conventional approaches starting in the luteal phase (“Luteal”), random-start, ...
A specific controlled ovarian stimulation (COS) protocol for fertility preservation in women with breast cancer undergoing neoadjuvant chemotherapy
(2017-01-01)
Aim of the study: The authors present a novel and specific controlled ovarian stimulation protocol for fertility preservation in women with estrogen-positive receptor breast cancer undergoing neoadjuvant chemotherapy. The ...
The impact of letrozole administration on oocyte morphology in breast cancer patients undergoing fertility preservation
(2020-04-01)
Objective: Patients submitted to oncological fertility preservation with letrozole and gonadotropins seem to present a higher rate of immature oocytes and lower fertilization rates in comparison to infertile patients ...
Cost-effectiveness comparison between pituitary down-regulation with a gonadotropin-releasing hormone agonist short regimen on alternate days and an antagonist protocol for assisted fertilization treatments
(2013-05-01)
Objective: To compare cost-effectiveness between pituitary down-regulation with a GnRH agonist (GnRHa) short regimen on alternate days and GnRH antagonist (GnRHant) multidose protocol on in vitro fertilization (IVF)/intr ...

Polycystic ovary syndrome and their implications in metabolic disorders: New targeted therapies for improving reproductive outcomes
(2013-03-01)
The natural process of ovulation occurs when the egg is released from the mature follicle. Although many follicles start growing, only a small number reaches maturity and ovulates. The majority of ovarian follicles suffer ...
Influence of Superovulatory Protocols on In Vitro Production of Nellore (Bos indicus) Embryos
(Wiley-Blackwell Publishing, Inc, 2010-10-01)
There are indications in the literature that delaying the period between ovarian superestimulation and ovum pick up (OPU) would induce follicles to a condition of initial atresia, which could be beneficial to oocyte ...
