What We Still Don't Know About the Long - Term Health Risks
of Ovarian Stimulation and Egg Retrieval, RHTP (2016)
Success rates for IUI are approximately 15 percent to 20 percent per cycle and vary based on a number of factors, such as your age, type
of ovarian stimulation, motility of sperm, among others.
The benefit
of the ovarian stimulation portion of IVF is less than ideal.
This is likely due to the effects
of ovarian stimulation on the endometrial lining, making it a bit resistant to implantation in a fresh cycle.
We concluded that the fresh transfer was impaired by the residual effects
of ovarian stimulation on the uterine lining, reducing its receptivity to embryos.
The most notable effect
of ovarian stimulation is multiple pregnancies.

Specifically, a 2012 study by suggested that 28.6 percent and 9.3 percent
of mothers undergoing
ovarian stimulation experienced twin and higher - order pregnancies, respectively.
In other words, about 10 percent
of women who successfully undergo
ovarian stimulation end up having multiple children in one pregnancy.
Our fertility specialist and caring staff will walk you through every step
of the IVF process:
ovarian stimulation, egg retrieval, fertilization, ancillary IVF services, embryo transfer and luteal phase support.
Other
stimulation can increase your risks
of a multiple pregnancy or
ovarian hyperstimulation syndrome (OHSS).
PFC was one
of the initial study sites for FDA approval
of the Follistim Pen, an FSH medication delivery device that today has made fertility drug administration much easier and comfortable for patients and is now widely used for
ovarian stimulation.
This «freeze - all» approach, initially developed as a strategy for minimising risk
of ovarian hysperstimulation syndrome (OHSS) in high risk patients, also addresses concerns that some have raised that the drugs used for
ovarian stimulation during IVF may have a negative impact on the uterine receptivity
of some patients.
But in the meantime, non-IVF fertility treatments such as
ovarian stimulation and ovulation induction — for instance, with the drug clomiphene citrate — have increased to become the predominant source
of medically assisted multiple births in the country while IVF is increasingly producing twins.
The study also showed that the number
of eggs retrieved after
ovarian stimulation in one cycle does not influence the live birth success rate in subsequent cycles.
«We have improved both the technical skills in the laboratory and the clinical skills
of the doctors and also perform milder
ovarian stimulation.
Between them lies the common approach
of IUI, with prior
ovarian stimulation to increase the number
of leading follicles and thereby the chance
of pregnancy.
Given this risk, it is also a matter
of some controversy
of how the
ovarian stimulation for IUI should be performed, either with a course
of routinely used injections
of follicle stimulating hormone (FSH) or a shorter course
of the non-hormonal drug clomiphene citrate.
From advances in detecting
ovarian cancer, to electronic brain
stimulation, to the unearthing
of a new dinosaur, to using chemistry to preserve priceless art, countless groundbreaking discoveries are made right here in Philadelphia.
Some women, particularly women with Polycystic
Ovarian Syndrome (PCOS), experience «multiple follicular
stimulation», a condition in which more than one follicle is selected during the course
of a cycle.
Results were controlled for other sources
of energy, infertility diagnosis,
ovarian stimulation protocol, body mass index (BMI) and smoking status.
Furthermore, high blood levels
of insulin can act by increasing androgenous hormonal
stimulation of the
ovarian theca cells as well as potentiating gonadotropin - stimulated
ovarian androgen steroidogenesis — although recent data has suggested that the insulin - induced increase in
ovarian hormone secretion is not accompanied by increased steroid metabolism.74 Hyperinsulinaemia may also affect the central actions
of androgen by impairing progesterone inhibition
of the gonadotropin - releasing hormone pulse generator.75 Insulin has also been shown to increase expression
of adrenal steroidogenic enzyme mRNA47 as well as adrenal responsiveness to adrenocorticotropic hormone.76
