About the course

Six lectures and two discussions on controlled ovarian stimulation and endometrial preparation for frozen embryo transfer.

A practical masterclass on controlled ovarian stimulation — from the physiology of folliculogenesis and basic protocols to personalisation, random-start/DuoStim, complication prevention and endometrial preparation for frozen embryo transfer. Six lectures by leading Ukrainian reproductologists and two live discussions covering practical clinical questions. Recorded at UARM 2026, Bukovel.

What you will learn

Folliculogenesis regulation

Understand gonadotropin-dependent and -independent stages of follicle growth, the FSH window and intra-ovarian factors as the physiological basis for protocol choice.

Basic stimulation protocols

Confidently apply agonist and antagonist protocols, the choice of gonadotropins and starting dose, individualised to ovarian reserve.

Personalisation and protocol evolution

Understand what drives protocol choice today and how freeze-all and cycle segmentation reshaped decision logic.

Random-start and DuoStim

Know when to start stimulation regardless of cycle phase and how DuoStim raises cumulative oocyte yield in challenging patients.

Complication prevention

Assess ovarian hyperstimulation risk, use an agonist trigger and freeze-all, and choose the final maturation trigger correctly.

Endometrial preparation for FET

Choose between natural, modified natural and hormone replacement cycles, monitor progesterone and synchronise the implantation window.

Who is this course for
  • Reproductive specialists and OB-GYNs running ART programmes
  • ART clinic physicians working with ovarian stimulation and frozen embryo transfer
  • Clinicians adopting personalised protocols, random-start and DuoStim
  • Specialists aiming to reduce stimulation complications and improve endometrial preparation

Course content

1

Modern understanding of folliculogenesis regulation

Stimulation begins with physiology. How gonadotropin-dependent and -independent stages of follicle growth, the FSH window and intra-ovarian factors determine why some protocols work and others do not — and how to read this at the individual patient.

Basic protocols of controlled ovarian stimulation: the tools we have

Master the fundamentals before adding complexity. Agonist and antagonist protocols, choice of gonadotropins and starting dose, individualisation to ovarian reserve — the systematic toolkit every stimulation programme starts from.

3

Evolution of controlled stimulation protocols: selection factors and shifting paradigms

The stimulation paradigm has shifted from 'more oocytes at any cost' to personalisation and safety. Which factors really drive protocol choice today, how freeze-all and cycle segmentation changed decision logic, and where the limits of reasonable individualisation lie.

Random-start protocols and DuoStim: new options in modern practice

The classic 'day 2–3' start is no longer the only option. When it is appropriate to start stimulation regardless of cycle phase, how dual stimulation (DuoStim) raises the cumulative oocyte yield in challenging patients, and where the limits of these approaches lie.

Complications of controlled stimulation: what can be prevented and avoided

Most stimulation complications are predictable. How to assess the risk of ovarian hyperstimulation syndrome, when an agonist trigger and freeze-all are the rescue, how to choose the final maturation trigger, and which mistakes cost a cycle — a practical review of prevention.

Endometrial preparation for cryotransfer: a gallery of protocols

Natural, modified natural or hormone replacement cycle — what determines the choice? A comparison of endometrial preparation protocols for frozen embryo transfer, the role and monitoring of progesterone, and synchronising the implantation window with embryo transfer.
