Methods of Medically Assisted Reproduction

Overview of common MAR methods: insemination, IVF/ICSI, cryopreservation, and donation.

The methods of medically assisted reproduction are a set of medical procedures used to help couples facing infertility achieve a pregnancy. These procedures involve the use of medical technologies and careful monitoring of the reproductive process, with the aim of achieving a successful conception.

The methods differ in complexity, scope of stimulation, laboratory steps and average success rates. In practice this means that MAR can be relatively straightforward, such as intrauterine insemination (IUI), or more complex, such as IVF/ICSI procedures and frozen embryo transfer (FET).

Page Overview

When do we consider ART methods?

The decision to use assisted reproduction methods is not taken hastily, but when there are clear medical reasons or limited time to wait. In some situations ART methods can significantly increase the chances of achieving pregnancy.

ART methods should be considered: 

  • after a longer period of trying without pregnancy
  • in the case of a known cause of infertility (male factor, absence of ovulation, tubal patency...)
  • after repeated miscarriages or implantation failures
  • when, due to age or findings, it is advisable not to postpone the procedure

The first step is always a conversation and a work-up. Only after that does it make sense to choose an ART method.

Main methods at Cito Polyclinic

Although there are many terms and abbreviations, most procedures can be reduced to a few main methods. All other techniques are an extension of, or support for, one of these.

IUI

Intrauterine insemination

A simpler procedure in which previously prepared sperm is introduced directly into the uterus at the time of ovulation, with or without mild ovarian stimulation.

IVF

In vitro fertilisation

A standard assisted reproduction procedure in which egg cells are aspirated from the ovaries after stimulation, and fertilisation takes place in the laboratory.

ICSI

IVF with microinjection

A variant of IVF in which the embryologist injects a single sperm directly into the egg cell, particularly in cases of a more pronounced male factor.

FET

Frozen embryo transfer

Transfer of previously frozen embryos into a naturally or medically prepared uterine lining, without new ovarian stimulation.

Micro-TESE and TESA

Surgical procedures for treating male infertility

Micro-TESE is a microsurgical procedure to retrieve sperm from the testicle in a man with azoospermia for the purpose of an assisted reproduction procedure.

TESA is a minimally invasive procedure of aspirating sperm from the testicle for the purposes of an IVF/ICSI procedure.

DNA FRAGMENTATION

DNA fragmentation test

This test assesses damage to the genetic material of sperm and assists in the work-up of male infertility.

 Intrauterine insemination (IUI)

IUI is a procedure in which the doctor uses previously selected sperm from your partner and places them directly into the uterus at the most suitable moment to increase the chances of pregnancy. IUI is a lower-complexity ART method.

When is it considered?

  • mildly reduced sperm count or motility
  • unexplained cause of infertility with a good ovarian reserve
  • younger couples in whom we wish to start with a less invasive procedure

IUI is not the solution for every situation. If we assess that the chances are realistically very low, we will openly suggest going straight to IVF/ICSI.

What does an IUI cycle look like?

Intrauterine insemination is a simple and short procedure carried out in a few clear steps:

  • Mild ovarian stimulation or a spontaneous cycle.

    Depending on your situation, the procedure can be performed in a natural cycle or with mild hormonal therapy that helps the egg cell mature.

  • Tracking follicular growth and ovulation by ultrasound.

    With regular ultrasound examinations we monitor follicular growth and determine the best moment for the procedure.

  • Processing the sperm sample in the laboratory.

    The sperm sample is carefully processed in order to isolate the highest-quality sperm.

  • Application of the prepared sample into the uterus.

    At the optimal time, the prepared sample is gently applied into the uterus through a thin catheter. The procedure is quick and largely painless.

 IVF – in vitro fertilisation

IVF is the most common ART method, involving the aspiration of egg cells from the woman's ovaries, which are then fertilised with the partner's sperm in specially equipped laboratory conditions. This procedure allows the creation of embryos that are later transferred back into the uterus or frozen.

When do we most often recommend IVF?

  • long-standing infertility with findings that indicate the need for a more intensive approach
  • impaired patency or absence of the fallopian tubes
  • a more pronounced male factor
  • after several unsuccessful IUI attempts

Basic steps of the IVF procedure

IVF (in vitro fertilisation) consists of several clearly defined phases. Although it may sound complex, the entire procedure is well planned and carried out under the constant supervision of an expert team.

  • ovarian stimulation and monitoring of follicular growth
  • follicular puncture and collection of egg cells
  • fertilisation in the laboratory (classical IVF or ICSI)
  • embryo cultivation over several days
  • transfer of one or more embryos, with the possibility of freezing the surplus embryos

 A detailed description of the IVF procedure itself is available on the IVF programme page, and during the consultation we also go through the possible risks, side effects and the course of recovery so that you enter every step informed and reassured.

ICSI – Intracytoplasmic sperm injection

ICSI is a method in which a single sperm is selected, activated and injected into the egg cell under the microscope using a glass microinjection pipette. It is used in cases of male infertility, when the sperm are unable to fertilise the egg on their own. It does not alter the genetic material, only the way in which the sperm and the egg cell meet.

When do we consider ICSI?

  • markedly reduced sperm count, motility or morphology
  • sperm obtained surgically (e.g. TESA, TESE)
  • a previous IVF cycle with no fertilisation or with a very low number of fertilised egg cells

What you should know about the ICSI method 

The decision on ICSI is made individually for each couple and for each procedure. In some couples we combine classical IVF and ICSI on different egg cells in order to gather as much information as possible about the best approach.

FET – transfer of frozen embryos 

FET (cryo-embryo transfer) is a procedure in which previously frozen embryos are transferred into a prepared uterine lining. It is most often carried out after a successful IVF procedure in which several good-quality embryos were obtained. Instead of repeating the entire IVF cycle, FET makes it possible to use already existing embryos in one of the subsequent cycles.

What are the advantages of FET?

  • no repeated ovarian stimulation or puncture
  • a more flexible choice of transfer date
  • the possibility of planning a pregnancy after a break or after childbirth

FET is often part of a broader ART plan. A single IVF cycle can include several FET cycles, depending on the number of frozen embryos and your wishes, without the need to repeat the whole IVF procedure.

What does a FET cycle look like? 

A FET cycle is simpler and shorter than a new  IVF procedure. It is carried out in a few clearly defined steps, with careful planning of the optimal moment for the transfer.

  • Monitoring of the natural cycle or medicated preparation of the endometrium.

    Depending on your cycle and the medical assessment, FET can be performed in a natural cycle or with mild hormonal therapy that prepares the uterine lining (endometrium).

  • Selection of the appropriate embryo and thawing on the day of the transfer. 

    On the day of the transfer the highest-quality frozen embryo is selected and then carefully thawed in the laboratory.

  • Embryo transfer into the uterus.

    The transfer itself is quick and is most often performed without anaesthesia. Most women describe it as an uncomfortable but not a painful procedure.

Additional laboratory techniques in ART

Alongside the basic methods, there are also additional laboratory techniques used in selected couples when there is a clear clinical indication. They do not replace the basic procedures but complement them.

IMSI PICSI Assisted hatching EmbryoGlue Time-lapse inkubator

Examples of when we consider additional techniques

  • Repeated unsuccessful implantations despite embryos of excellent quality
  • A more pronounced male factor (e.g. IMSI/PICSI in certain findings)
  • Certain genetic diagnoses or hereditary conditions (PGT-M/PGT-A by indication)

We never introduce additional techniques routinely for everyone; we consider them individually with the couple, explaining the expected effect and limitations.

How do we choose the optimal ART method?

The decision on the optimal ART method is not based on a single finding. We take several key elements into account and only after a conversation propose an approach that makes sense for you specifically.

1
Diagnosis and history

How long you have been trying, whether there have been previous pregnancies or miscarriages, whether any surgeries were performed, and what previous findings and procedures look like.

2
Age and ovarian reserve

Age and the ovarian reserve result are one of the main criteria – e.g. with a significantly reduced reserve we often skip IUI and propose an earlier move to IVF/ICSI.

3
Male factor and additional tests

The semen analysis, additional tests and a urological examination show whether it makes sense to plan IUI or whether it is more reasonable to go straight to IVF/ICSI.

4
Your wishes, options and pace

We also take your daily life into account - time, work, family, travel and financial possibilities - so that we adapt the plan to your rhythm and not the other way round.

IUI or IVF — how to decide?

The question „should we first try IUI or go straight to IVF?” is one of the most common. The answer depends on several factors: age, findings, the duration of infertility and previous attempts.

There is no single rule that applies to all couples. In general, in younger patients with normal findings we consider up to 3 IUI attempts, while in women older than 35 or with a reduced ovarian reserve we often recommend a quicker move to IVF/ICSI.

These recommendations are approximate. In your case we always clearly explain why we propose a specific number of attempts and in what order. Our aim is for you to have a clear plan and realistic expectations. 

Element IUI IVF / ICSI
Invasiveness minimal, without puncture moderate, puncture required
Need for stimulation often mild or a spontaneous cycle always ovarian stimulation
Average chance per cycle* around 5–15% around 30–55%
When is it considered? mild male factor, unexplained infertility, good reserve a more pronounced male factor, risk to the fallopian tubes, a lower reserve

*The figures are approximate and vary from couple to couple. At the consultation we talk about your realistic chances, not about general averages.

Genetic and immunological tests — when and why?

Advanced genetic and immunological tests are not performed routinely for every couple. We consider them when there are specific indications, such as recurrent miscarriages, certain hereditary diseases or specific findings in the medical history.

  • Karyotype of the partners (chromosomal tests)
  • Selected genetic panels in cases of suspected hereditary diseases
  • Thrombophilia tests in cases of recurrent miscarriages
  • Selected immunological tests with a clear indication

Why undergo ART procedures at Cito Polyclinic?

At Cito Polyclinic we do not talk only about the procedure, but about a series of decisions. It is important to us that every one of them makes sense for you. 

PLAN

We do not guide you through procedures „on autopilot”

We do not start anything without a clear diagnosis and an explanation of all findings. If we assess that a particular method does not make sense in your situation, we will tell you so openly. The plan is adapted to your findings and to the body's response during the cycle.

TIM

Experienced multidisciplinary team

Gynaecologists, subspecialists in human reproduction who are leaders in the ART field with more than 4,000 completed procedures, embryologists, anaesthetists and, when needed, a urologist are involved in the planning and delivery of the procedures.

INFO

We speak clearly and honestly 

No promises, no embellishment of success rates. Each method is explained in simple language with a realistic presentation of success rates and risks, so that you can make an informed decision.

SUPPORT 

Continuous support throughout the entire journey

We know that questions most often arise at home, not in the surgery. From the first contact to the follow-up after the procedure we try to be available for questions and uncertainties, by phone or by email.

Procedure price list 

Prices are defined transparently and in line with the type of procedure and the medical services included. The final price is determined according to the recommended procedure and the individual plan for each couple. 

At the first consultation we explain in detail all the costs, what is included in the price of an individual procedure and what is charged additionally - with no hidden costs.

You can get the first available consultation appointment by phone on +385 21 457 800 or by sending a short message via the contact form.
