Cancer Clinical Trial
— FertiTOXOfficial title:
FertiTOX - Platform for Fertility Related Gonadotoxicity of Cancer Therapies
The goal of this observational study is to learn how gonadotoxic treatments (chemotherapies, radiotherapies or immunotherapies) affect the fertility status of participants with cancer. The main questions it aims to answer are: - in females, if cancer therapies reduce the Anti-Müllerian hormone (AMH) concentration (ovarian reserve); - in males, if cancer therapies reduce sperm concentration (sperm quality).

Primary | Anti-Müllerian hormone (AMH) concentration in females | Fertility status after gonadotoxic treatment in females (referring to ovarian reserve). Blood will be drawn to measure AMH concentration. Unit of measure: for serum AMH value is picomol per liter (pmol/L). |
Change from baseline in AMH concentration at 12-15 months after the end of gonadotoxic treatment | |
Primary | Anti-Müllerian hormone (AMH) concentration in females | Fertility status after gonadotoxic treatment in females (referring to ovarian reserve). Blood will be drawn to measure AMH concentration. Unit of measure: for serum AMH value is picomol per liter (pmol/L). |
Change in AMH concentration at 5 years after time point 12-15 months after the end of gonadotoxic treatment | |
Primary | Anti-Müllerian hormone (AMH) concentration in females | Fertility status after gonadotoxic treatment in females (referring to ovarian reserve). Blood will be drawn to measure AMH concentration. Unit of measure: for serum AMH value is picomol per liter (pmol/L). |
Change in AMH concentration at 10 years after time point 12-15 months after the end of gonadotoxic treatment | |
Primary | Sperm concentration in males | Fertility status after gonadotoxic treatment in males (referring to sperm quality). Participants provide the laboratory with a sperm sample for analysis. Unit of measure: for sperm concentration is millions per milliliter (10^6/mL). |
Change from baseline in sperm concentration at 12-15 months after the end of gonadotoxic treatment | |

Secondary | Fertility preservation measures performed | Proportion of female participants who freeze their ovarian tissue, oocytes, zygotes or embryos. Proportion of male participants who freeze their sperm or testicular tissue. |
Before the start of gonadotoxic treatment | |
Secondary | Satisfaction with the fertility preservation counselling before the gonadotoxic treatment | Both female and male participants will have to rate their counselling satisfaction by choosing a score on a scale from 1 to 10. Value 1, being the lowest score (not satisfied at all) and value 10 being the highest score (very satisfied). | 12-15 months after the end of gonadotoxic treatment | |
Secondary | Satisfaction with the decision to have undergone fertility preservation measures or not | Both female and male participants will have to rate their decisional satisfaction by choosing a score on a scale from 1 to 10. Value 1, being the lowest score (not satisfied at all) and value 10 being the highest score (very satisfied). | 12-15 months after the end of gonadotoxic treatment | |
Secondary | Number of spontaneous pregnancies and children born | Pregnancies which occured naturally, without the help of fertility preservation measures. | 12-15 months, 5 years and 10 years after the end of gonadotoxic treatment | |
Secondary | Number of pregnancies and children born with the help of fertility preservation measures | Pregnancies which occured with the help of fertility preservation measures (in females: frozen ovarian tissue, oocytes, zygotes or embryos, and in males: frozen sperm or testicular tissue). | 12-15 months, 5 years and 10 years after the end of gonadotoxic treatment | |
Secondary | Quality of life assessment | Short-Form 12-items health survey (SF-12, version 2) is a questionnaire that consists of 12 questions. It investigates the participant's state of health through 8 different dimensions: general health perception (1 question), physical health (2 questions), limited physical role function (2 questions), physical pain (1 question), vitality (1 question), mental health (2 questions), limited emotional role function (2 questions) and social functioning (1 question). | 12-15 months, 5 years and 10 years after the end of gonadotoxic treatment |
