| description | Biochemical, Metabolic and Endocrine changes in PCOS result in reproductive impairment in women with PCOS. Controlled ovarian stimulation (COS) may be associated with • Unpredictable response • Response may be slow • Hyper-response - OHSS • Risk of Cyst Formation • Poor oocyte quality • Miscarriage • Cycle cancellation So, the ovulation induction protocol should be efficacious and safe resulting in a singleton live birth, minimising complications, and risks like ovarian hyperstimulation syndrome (OHSS), multiple pregnancies and cancellation of cycles. For this special consideration should be given to prediction of response, pre-treatment, choosing the right ovulation induction (OI) protocol with right dose and analogue, using GnRH agonist trigger instead of hCG, preventing late follicular phase rise in progesterone, or following the segmentation protocol. We can maximize the success rates by stimulation individualization based on age, AMH, AFC and amended further for BMI. AMH is considered as more sensitive marker to define follicle excess than AFC as it appraises more follicle classes - preantral and early antral. One should probably use mild stimulation protocols where gonadotropins are given in combination with oral ovulogens or the low dose step up protocol. It is essential that we use GnRH antagonist protocol and administer GnRH agonist if there is risk of OHSS. If segmentation protocol is used one could also use the progesterone primed ovarian stimulation instead of GnRG antagonist. One could reduce the incidence of OHSS by laparoscopic ovarian drilling and use of Metformin and aspirin before assisted reproduction. If the patient is at risk of developing OHSS during stimulation then one could administer cabergoline, intravenous infusion of calcium gluconate or albumin and methylprednisolone. But freezing all embryos and transferring them in a subsequent cycle increase the efficacy and reduce complications of ART in PCOS women. Elective single embryo transfer(eSET) should be the norm to reduce the multiple pregnancy rate. Conclusion Thus, in all ART cycles individualised COS with freeze all and eSET could help in increasing the success of ART and reducing stress and anxiety and complications in these women. |
