OBJECTIVE To compare the effectiveness of an electrocautery strategy with ovulation induction using recombinant follicle stimulating hormone in patients with polycystic ovary syndrome. DESIGN Randomised controlled trial. SETTING Secondary and tertiary hospitals in the Netherlands. PARTICIPANTS 168 patients with clomiphene citrate resistant polycystic ovary syndrome: 83 were allocated elec...

Metformin alone compared with placebo increases the ovulation rate in women with polycystic ovary syndrome (PCOS) but should not be used as first-line therapy for anovulation because oral ovulation induction agents such as clomiphene citrate or letrozole alone are much more effective in increasing ovulation, pregnancy, and live-birth rates in women with PCOS. There is fair evidence that metform...

Ovulation in camelids is induced by an unidentified protein in the seminal plasma of the male termed 'ovulation-inducing factor'. This protein has been reported to be a 14-kDa protein under reducing conditions, which, when purified from seminal plasma, induces ovulation in llamas. The identification of this protein and investigation of its potential to induce ovulation in camelids may aid the d...

Abstract
 Aim: Low level laser therapy (LLLT) has been used in biostimulation of rat ovaries using a fibreoptic introduced directly through the vagina to deliver doses, which is new modality induction ovulation, compared with conventional medical ovulation clomiphene citrate and non-interventional controls. 
 Study design: A Prospective experimental study carried out from January 2014...

Injection of human Chorionic Gonadotropin (hCG) directly into the dorsal lymph sac of Xenopus is a commonly used protocol for induction of ovulation, but recent shortages in the stocks of commercially available hCG as well as lack of a well tested alternative have resulted in frustrating experimental delays in laboratories that predominantly use Xenopus in their research. Mammalian Luteinizing ...

Whether recombinant gonadotrophin products do, indeed, represent progress for routine ovulation induction and IVF cycles, in comparison with urinary products, has remained controversial. Here we review published data with regard to respective risks, outcomes and cost for both medication options. Safety considerations favour recombinant products, while overall outcome and cost considerations fav...
