LISBON -- Women undergoing assisted reproduction had similar pregnancy rates with gonado-tropin-releasing hormone agonist and antagonist protocols, but less ovarian hyperstimulation
syndrome with the GnRH-antagonist protocol in a large randomized trial.
PCOS patients, who are infertile encountered with many problems in a controlled ovarian hyperstimulation
Conventional IVF uses high doses of hormones, which carries higher risks of ovarian hyperstimulation
syndrome, which can be serious and occasionally fatal.
In- Vitro Fertilization ( IVF) comes with several risks, with one of them during the phase of artificial stimulation of the ovaries called Ovarian Hyperstimulation
Syndrome ( OHSS).
Likewise, in ovarian hyperstimulation
, whether due to drug stimulation for infertility or gestational trophoblastic disease, bilateral enlarged ovaries have multiple cysts called theco-luteal cysts.
And other risks of fresh IVF transfer, such as ovarian hyperstimulation
syndrome, can be virtually eliminated when frozen/thaw transfers are employed.
FSHoma is difficult to diagnose and is usually associated with ovarian hyperstimulation
syndrome seen in women in pre-menopausal period (3), (6).
Controlled ovarian hyperstimulation
and induction of multifollicular growth; 2.
Ovarian stimulation has been shown to have adverse effects on endometrial receptivity and the risk of ovarian hyperstimulation
syndrome (OHSS) is also increased when embryo transfer is performed in the stimulated cycle.
From an October 2010 conference in London, 18 articles consider such topics as stem cells in endometrium and their role in the pathogenesis of endometriosis, ovarian cryopreservation strategies and the find control of ovarian follicle development in vitro, strategies to improve embryo implantation to supraphysiological rates, intensive care treatment of ovarian hyperstimulation
syndrome, and long-term progestin-only contraception in humans versus animal models.
Problems caused by GnRH agonists were mid-cycle gonadotrophin flares, a high incidence of multiple pregnancies and ovarian hyperstimulation
It should be noted that low dose hCG when used alone during the late follicular phase during controlled ovarian hyperstimulation
has been shown to stimulate the growth of larger follicles while inhibiting the growth of smaller follicles, but it is unlikely that this is an explanation for hCG associated weight loss.
