Centre for Fertility Preservation: A Ray of Hope

Survival rates among childhood cancer patients have progressively increased over the past four decades particularly due to advancements in cancer care. Presently, 3 out of 4 children diagnosed with cancer are cured from their disease. However, this success comes at a cost as nearly 60% of cancer survivors face infertility or even sterility due to effects of cancer and/or its treatment including chemo- and radiotherapy.  Chemotherapy also is often used for non-cancerous conditions such as autoimmune diseases like systemic lupus erythematosus (SLE) and hematological diseases. The American Society of Clinical Oncologists (ASCO) & American Society of Reproductive Medicine (ASRM) recommends informing cancer patients about the options available to preserve their fertility. Though fertility preservation is a gaining popularity in developed countries, it is not so in India due to lack of facilities and skilled personnel in this field.

 The Centre for Fertility Preservation (CFP) at Kasturba Medical College, Manipal is the first centre in the country to start fertility preservation and still remains one of the very few centres in the country offering male and female fertility preservation options for prepubertal and young adult cancer patients.  CFP is a global partner of the Oncofertility Consortium, USA along with active collaborations with world’s leading universities and institutes in Europe such as University of Muenster, Germany, University of Naples, Italy and University of Edinburgh, UK.

 

Fertility preservation services offered at CFP:

Men:

Sperm Banking: It is a simple way to preserve fertility in post pubertal and adult males, with a generally high success rate.  Semen samples are collected through masturbation, before treatment begins. Multiple collections (2-3) allow for more reproductive chances in future.

 

Testicular sperm retrieval: In cases of severe low sperm concentration or no sperm in ejaculate, sperm can be retrieved from the testicles of young adult males by surgical extraction and frozen for future use.

 

Women:

 

Embryo freezing: It is the most widely used fertility preservation method, and it is considered the best option for patients who are married or have a male partner. During this process, a woman’s ovaries are first hormonally stimulated to mature multiple eggs, which are then removed and fertilized through in vitro fertilization (IVF) with sperm to create embryos in the lab.  The embryos are then frozen for future use. The entire duration of the procedure can range from 2-4weeks.  

 

 

 

Oocyte freezing : This is a good option for single women who are unmarried/do not have a male partner/do not want to use donor sperm. It is similar to embryo banking except that the eggs are NOT fertilized before freezing. The entire duration of the procedure can range from 2-4weeks.  

 

Children/Adolescents:

Immature testicular tissue freezing in prepubertal boys: In children where there is no sperm production yet, immature testicular tissue freezing is offered. It is a simple surgical procedure where immature testicular tissue is removed and frozen for future use. This tissue contains stem germ cells which can be used to produce sperm in the future. While this method is currently considered experimental it is the best available option for pre-pubertal boys. When needed, the testicular tissue can either be transplanted back to the patient or used to generate sperm cells in the lab which then can be used to have a baby of their own through IVF technology.

 

Ovarian tissue freezing in pre & post-pubertal girls: In this procedure, an entire ovary or part of an ovary is removed laparoscopically and the outer surface (cortex) containing the immature eggs is frozen in strips for later use. Later, the patient can have pieces of the tissue transplanted back into her. A number of pregnancies have resulted from using this technique. In certain cases where a transplant is not safe because of the risk of re-seeding the original cancer, the tissue is used for maturating the follicles in the lab to harvest mature eggs. These eggs can then be used for fertilization and embryo production. Ovarian tissue freezing technique is currently experimental in prepubertal girls but may be the best available option for in small girls or women who must start their treatment immediately.

The uniqueness of the Centre for Fertility Preservation (CFP) at KMC Manipal, is that it bridges bench-to-bedside by also conducting intensive research, both clinical and fundamental, in the field of oncofertility, which is translated to patient care. CFP has received several research grants from national and international funding agencies. It also offers a vibrant PhD and postdoctoral program for young talents interested to explore various fundamental and applied aspects fertility preservation through multidisciplinary approaches. In addition, the centre has ongoing research activities in collaboration with Indian premier institutes in India like Indian Institute of Sciences (IISc), National Center for Biological Sciences (NCBS), National Institute of Immunology (NII) etc.

The primary goal of CFP is to make fertility preservation a routine practice in cancer care in India. CFP is actively collaborating with fertility clinics and cancer institutes across the country to promote and bring awareness among healthcare workers on the available options. Quoting an anonymous cancer survivor, “The goal is to bring quality to the lives we fought so hard to keep. We want lives that are rich, we want children and we want to be happy.” The Centre for Fertility Preservation aims to make this a reality for most if not all young cancer survivors in the near future.
