BACKGROUND Ovarian epithelial dysplasia was first described after prophylactic oophorectomies for genetic risk. Ovarian stimulation has been considered as a risk factor of ovarian cancer by Fathalla's incessant ovulation theory. In this study, we have investigated the risk of ovarian dysplasia after ovulation induction. METHODS We reviewed 99 oophorectomies or cystectomies between 1990 and 20...

Ovarian stimulation is performed in assisted reproductive technology (ART) to increase the yield of oocytes and embryos. The stimulation involves a daily hormonal injection, which causes discomfort and inconvenience to the patients. The medication is expensive and the treatment requires frequent ultrasound scans and medical visits. Ovarian stimulation also exposes the patients to the risk of ov...

The fertility preservation (FP) field has developed in the two decades and offers women possibility to have genetic children at some point life. Fertility is urgent by definition, performed for social reasons or medical indications, such as impending gonadotoxic therapy radical gynaecological surgery. One year after pandemic was declared, COVID-19 infection imposed several restrictions limited ...

During the early follicular phase in the menstrual cycle, antral follicle sizes are often markedly heterogeneous. These follicular size discrepancies may, at least in part, result from the early exposure of FSH-sensitive follicles to gradient FSH concentrations during the preceding luteal phase. In addition, they potentially affect the results of ovarian stimulation. Indeed, pre-existing follic...

Ovarian hyperstimulation syndrome (OHSS) is still a severe complication due to controlled ovarian stimulation for artificial reproductive technology. Even though multiple techniques to avoid OHSS have been discussed in the last decades, up to now no clear concepts for primary and secondary prevention exist. This review gives an overview over proposed strategies to avoid OHSS. In a retrospective...

We report a very rare case of ovarian torsion following controlled ovarian stimulation for in vitro fertilization in which no oocytes were obtained at the time of ovum retrieval from the left torsed ovary. The patient was a 33-year-old nulligravida female undergoing controlled ovarian stimulation. On day 14, the patient complained of lower left abdominal pain with nausea. Transvaginal oocyte re...

The role of macrophage migration inhibitory factor (MIF) in human ovarian function remains obscure. The aim of this study was to investigate how MIF was related to ovulation by quantitative analysis of serum, follicular fluid and culture medium of granulosa cells obtained from in-vitro fertilization (IVF) and embryo transfer patients. Serum MIF concentrations in ovarian stimulation cycles for I...

We studied the effects of repeated stimulation by recombinant human FSH (rhFSH) at various time intervals during a physiologic breeding season in rhesus monkeys. Ovarian recovery and responses were assessed by ultrasonography, serum steroid concentrations, number of oocytes retrieved, and in vitro blastocyst development following IVF. One group underwent a single stimulation regimen with 18 IU ...

In the last decades, several steps have been made aiming at rendering human IVF more successful on one side, more tolerable on the other side. The "mild" ovarian stimulation approach, in which a lower-than-average dose of exogenous gonadotropins is given and gonadotropin treatment is started from day 2 to 7 of the cycle, represents a significant step toward a more patient's friendly IVF. Howeve...

Adverse drug reactions (ADRs) are a major problem in drug therapy and drug development. Inter-individual genetic differences can have significant roles in determining an individual’s susceptibility to ADRs. The rapid development of techniques in the area of genome analysis has put the scientific community in a power position and facilitated identification of new pharmacogenomic biomarkers that ...
