About me
- My specific area of interest and expertise focuses on the impact of cancer
treatment on fertility potential and the prevention of infertility through
fertility preservation strategies. This new medical field has been recently
recognized and it could be named “Reproductive Oncology”. In the U.S. the
term “Oncofertility” has become popular. As several methods are available
for fertility preservation and those are currently used for cancer patients,
I consider of outmost importance the investigation of their safety in the
oncological context.
My research is supported by the Clinical Investigator’s grant from
Stockholm county council, the Swedish research council, the Swedish Childhood
Cancer Foundation, Radiumhemmets Research Fonds, the Cancer foundation, and
Karolinska Institutet.
I completed my medical education and my residency in obstetrics and
gynecology in my home country, Colombia. As specialist I was then awarded a
fellowship from the Groupement Français de Gynécologie de l’Enfant et de
l’Adolescence and completed my training in Pediatric Gynecology at Hôpital
Necker Enfant Malades in Paris, as well as in Reproductive Endocrinology,
Infertility and Assisted Reproduction at Cochin-Baudelocque. In 2005 I earned
her PhD degree at Uppsala University in Sweden and since 2007, I am a Senior
Consultant in Reproductive Medicine at Karolinska Hospital in Stockholm and
Head of the Program for Fertility Preservation. I am currently sharing her
clinical work with both clinical and translational research. Since 2013, I am
an Associate Professor at Karolinska Institutet and in January 2017 I was
promoted to the position of University Lecturer in Reproductive Oncology at
the Department of Oncology-Pathology of Karolinska Institutet.
Research
- My research encompasses the impact of several variables and interventions,
such as the performance of ovarian surgery, even conservative and for benign
diseases, in the development of infertility, as well as the treatment of
infertility, in particular by using assisted reproductive techniques.
Psychological aspects of infertility after cancer, ethics in health care
provision and a better understanding of specific patient groups’ access and
barriers to healthcare are also subject of my research.
My research activity is clinically oriented and integrated into my clinical
work as senior consultant at the Reproductive Medicine clinic of Karolinska
University Hospital, where I have been the clinical responsible for the
program for fertility preservation since 2007, as well as into my current
clinical fellowship at the Department of Oncology of Karolinska University
Hospital. My Ph D thesis was dedicated to the study of health aspects in
menopause and after completed in 2005, I initiated independent research in
2007 on fertility preservation, which was thereafter supported by a fulltime
2-year postdoctoral grant from the Swedish Society of Medicine Research,
SSMF, and by a 3-year grant from the Swedish Research Council. Since then my
projects have developed into both clinical and experimental research and thus
my current research network includes clinicians and basic science
researchers. Our research results have contributed to the improvement of
potentially safer stimulation protocols for female patients with
hormone-sensitive tumors including breast cancer, one of the most challenging
patient groups in the field of fertility preservation. I have introduced the
use of aromatase inhibitors for stimulation protocols of patients with breast
cancer at Karolinska University Hospital in 2010 and shared my experience
with colleagues of several Swedish hospitals, who have thereafter implemented
those protocols at their hospitals successfully. Several of my current
projects in fertility preservation are prospective and of national coverage.
Those projects include the evaluation of safety and efficacy of fertility
preservation by surgical methods, such as in case of gynecological cancer,
and by the performance of assisted reproductive technologies.
I am currently a Principal Investigator and research team leader at the
department of Oncology-Pathology of Karolinska Institutet.

- Swedish Research Council1 January 2024 - 31 December 2026Not all women are born equal. Even if the pool of ovarian follicles first formed in the ovaries is similar in size, some women will run out of eggs much faster than others, through mechanisms that are mostly unknown. Ovarian aging occurs in all women, even in healthy individuals, with end of ovarian function and onset of menopause around the age of 50. This indicates that the ovary ages faster than any other organ of the body, but the specific rate of ovarian aging differs among individuals and will determine how long the woman will be fertile and also the age at which she will develop menopause. Premature ovarian aging is observed linked to genetic conditionsTurner syndrome, BRCA mutation carriers, among others. Also, women that receive chemotherapy for treatment for cancer, accelerate their ovarian aging and often become infertile and develop premature menopause, with multiple negative health implications. We wish to investigate the molecular mechanisms behind the inter-individual differences in ovarian aging. At our center for reproductive medicine patients are followed due to a risk for infertility and for premature menopause. The prospective clinical cohorts are followed through sequential measurements of ovarian reserve biomarkers, clinical data and biobanked ovarian tissue samples, and the data will be available for this investigation. This study would be of outmost importance for both cancer survivours and women suffering from early menopause.
