About this trial

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).

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Patients with cancer or with benign reasons undergoing chemotherapy and/or radiotherapy of the pelvis (females) and the testicles (males) and/or immune therapy;

Willing to participate;

Serum hormone analysis before gonadotoxic therapy (females) or serum hormone analysis and sperm analysis before gonadotoxic therapy (males).

Disqualifiers

Trial outcomes

Primary outcomes

1

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).

Time frame
Change from baseline in AMH concentration at 12-15 months after the end of gonadotoxic treatment
2

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).

Time frame
Change in AMH concentration at 5 years after time point 12-15 months after the end of gonadotoxic treatment
3

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).

Time frame
Change in AMH concentration at 10 years after time point 12-15 months after the end of gonadotoxic treatment
4

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).

Time frame
Change from baseline in sperm concentration at 12-15 months after the end of gonadotoxic treatment

Secondary outcomes

1

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.

Time frame
Before the start of gonadotoxic treatment
2

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).

Time frame
12-15 months after the end of gonadotoxic treatment
3

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).

Time frame
12-15 months after the end of gonadotoxic treatment
4

Number of spontaneous pregnancies and children born

Pregnancies which occured naturally, without the help of fertility preservation measures.

Time frame
12-15 months, 5 years and 10 years after the end of gonadotoxic treatment
