In Vitro Fertilization (IVF) has revolutionized the landscape of assisted reproduction, offering hope to couples struggling with infertility. While standard IVF procedures can be successful, some couples may consider additional interventions – known as “add-ons” – to further optimize their chances of a successful pregnancy. This guide delves into the world of Add-ons in IVF, exploring the latest and traditional options, efficacy rates, considerations for each, and relevant international guidelines.

The Human Fertilization and Embryology Authority (HFEA) in the UK provides a comprehensive list of add-ons offered by fertility clinics. Here, we explore some of the most common ones:

Assisted Hatching:

This technique involves creating a small opening in the zona pellucida, the outer shell surrounding the embryo. This aims to facilitate easier implantation by the embryo in the uterine lining .

Preimplantation Genetic Testing (PGT):

PGT involves testing embryos for chromosomal abnormalities before implantation. This can help select healthy embryos for transfer, potentially improving pregnancy success rates and reducing miscarriage risk . Techniques include PGT-A (aneuploidy), PGT-M (monogenic disease), and PGT-SR (structural rearrangement).

Endometrial Scratching:

This minimally invasive procedure involves creating microscopic scratches in the uterine lining, potentially promoting endometrial receptivity for embryo implantation .

Embryo Glue:

A solution applied to embryos before transfer, embryo glue aims to facilitate adhesion to the uterine lining, potentially improving implantation success .

Immunotherapy:

Immunotherapy approach involves modulating the immune system to create a more favorable environment for embryo implantation. Popular Immunotherapy options include Intralipid Therapy, IVIg – Intravenous immunoglobulin therapy in IVF , Granulocyte Colony-Stimulating Factor (G-CSF) Therapy

Time-Lapse Imaging (EmbryoScope):

This technology utilizes a specialized incubator with an integrated camera to continuously monitor embryo development. This allows for a more comprehensive evaluation of embryo quality compared to traditional static observations .

Mitochondrial Replacement Therapy (MRT):

MRT, a highly specialized technique, allows for the replacement of abnormal mitochondria in oocytes (eggs) with healthy ones from a donor, potentially reducing the risk of mitochondrial diseases in offspring .

PRP (Platelet-Rich Plasma) Therapy

PRP Therapy uses Platelet Rich Plasma (PRP) derived from the person’s to induce Ovarian regeneration and uterine regeneration before IVF. These are injected into the Ovaries or the endometrium to improve their function. This is because PRP is believed to contain several growth factors that play an important role in tissue regeneration by activating the latent stem cells in the tissue. It is theorized that it helps in healing the endometrium and ovaries as well as stimulates regeneration, which can result in improved ovarian function and improved endometrial thickness and receptivity when used as an adjunct to IVF.

Looking Ahead: The Future of IVF Add-Ons

The field of IVF add-ons is constantly evolving, with ongoing research exploring new approaches to optimize IVF success rates.

Recent Developments in IVF Add-Ons are:

Artificial Intelligence (AI) in Embryo Selection:

AI algorithms are being investigated to analyze embryo characteristics and potentially predict implantation potential with greater accuracy.

Next-Generation PGT Techniques:

Advanced PGT techniques are being developed to identify a wider range of genetic abnormalities and improve embryo selection further.

Microfluidics for Embryo Culture:

Microfluidics technology offers a controlled environment for embryo development, potentially improving culture conditions and implantation success.

Traditional Approaches and Complementary Therapies:

While IVF add-ons represent the cutting edge of assisted reproduction, traditional approaches and complementary therapies can also be explored in conjunction with standard IVF protocols. Here are a few examples:

  • Acupuncture: Research suggests acupuncture may potentially improve blood flow to the uterus and promote relaxation, potentially impacting implantation success .
  • Dietary Modifications: Maintaining a healthy diet rich in essential nutrients may contribute to overall health and potentially improve outcomes in IVF cycles .
  • Stress Management Techniques: Chronic stress can negatively impact fertility. Incorporating relaxation techniques like meditation or yoga may benefit overall well-being and potentially improve IVF outcomes .

It is important to remember that the efficacy of these approaches can be subjective and may vary among individuals. It is essential to discuss any complementary therapies with your healthcare provider to ensure they do not interfere with your IVF treatment plan.
