By learning the terminology associated with fertility, puberty, endocrine health, and reproductive medicine, parents, caregivers, survivors, healthcare professionals, and researchers can develop a deeper understanding of the lifelong health considerations associated with Wilms tumor treatment. This knowledge can support informed decision-making, strengthen survivorship planning, facilitate timely specialist referrals, and help ensure that children affected by Wilms tumor receive comprehensive, personalized, and holistic long-term care throughout adolescence and adulthood.

A-Z of Fertility, Puberty, Endocrine Health & Reproductive Medicine Terms

​​

Adolescent Development

Adolescent development refers to the physical, emotional, social, and psychological changes that occur during puberty and the teenage years. Children treated for Wilms tumor generally experience normal development, although certain cancer treatments may affect growth, hormone production, fertility, or sexual maturation. Ongoing monitoring helps identify concerns early and supports healthy development.

 

Delayed Puberty

Delayed puberty occurs when the physical changes associated with puberty begin later than expected. Certain chemotherapy drugs, radiation therapy, endocrine disorders, or treatment-related complications may contribute to delayed pubertal development. Endocrinologists can evaluate and manage puberty-related concerns when they arise.

 

Endocrine System

The endocrine system is a network of glands that produce hormones responsible for regulating growth, metabolism, puberty, reproduction, energy levels, and many other bodily functions. Some childhood cancer treatments can affect endocrine health, making long-term monitoring an important component of survivorship care.

​

Endocrinologist

An Endocrinologist is a physician who specializes in hormones, growth, metabolism, puberty, fertility, and endocrine disorders. Pediatric endocrinologists frequently care for childhood cancer survivors who experience treatment-related hormonal or developmental concerns.

​

Endocrinology

Endocrinology is the branch of medicine focused on the diagnosis, treatment, and management of hormone-related conditions. Endocrinology plays an important role in survivorship care because some cancer treatments can affect growth, puberty, fertility, and long-term endocrine function.

​

Fertility

Fertility refers to the ability to have biological children. Most children treated for Wilms tumor retain normal fertility, but certain chemotherapy drugs, radiation treatments, stem cell transplantation procedures, or endocrine disorders may increase the risk of reproductive complications later in life.

​

Fertility Assessment

A fertility assessment is a medical evaluation used to estimate reproductive health and future fertility potential. Assessments may involve hormone testing, imaging studies, medical history reviews, and specialist consultation. Fertility assessments are increasingly incorporated into long-term survivorship care programs.

​

Fertility Counseling

Fertility counseling provides education and guidance regarding the potential reproductive effects of cancer treatment. Counseling helps patients and families understand fertility risks, available preservation options, and future reproductive considerations. Early fertility discussions are increasingly recognized as an important aspect of comprehensive cancer care.

​

Fertility Preservation

Fertility preservation refers to medical strategies designed to protect future reproductive potential before cancer treatment begins. Depending on age, diagnosis, and treatment plans, fertility preservation options may include sperm banking, ovarian tissue preservation, egg freezing, or other emerging technologies.

​

Follicle-Stimulating Hormone (FSH)

Follicle-Stimulating Hormone (FSH) is a hormone involved in reproductive development and fertility. FSH levels are often measured when evaluating puberty, ovarian function, testicular function, and reproductive health. Abnormal FSH levels may indicate endocrine or fertility-related concerns.

​

Gonadal Function

Gonadal function refers to the ability of the ovaries or testes to produce reproductive cells and hormones. Cancer treatment may occasionally affect gonadal function, influencing fertility, puberty, hormone production, and reproductive health. Survivorship programs often monitor gonadal function in patients considered at risk.

​

Growth Delay

Growth delay occurs when a child's rate of growth is slower than expected. Growth can be influenced by nutrition, illness, hormonal factors, chemotherapy, radiation therapy, and other medical conditions. Monitoring height, weight, and developmental milestones is an important aspect of survivorship care.

 

Growth Hormone

Growth hormone is produced by the pituitary gland and plays a crucial role in normal childhood growth and development. Deficiencies in growth hormone can lead to reduced growth rates and other health concerns. Endocrine evaluations may include growth hormone assessment when growth abnormalities are suspected.

​

Growth Monitoring

Growth monitoring involves regularly measuring height, weight, and developmental progress to ensure healthy growth patterns. Childhood cancer survivors may undergo long-term growth monitoring to identify potential treatment-related complications affecting development.

​

Hormonal Health

Hormonal health refers to the proper production, regulation, and function of hormones throughout the body. Maintaining hormonal health is important for growth, puberty, metabolism, fertility, energy levels, and overall well-being. Survivorship care often includes monitoring hormonal function when treatment-related risks are present.

 

Hormone Replacement Therapy (HRT)

Hormone Replacement Therapy (HRT) involves administering hormones to replace those that the body is unable to produce adequately. HRT may be recommended for survivors who develop endocrine deficiencies affecting growth, puberty, fertility, or other hormonal functions.

 

Infertility

Infertility refers to difficulty achieving pregnancy or fathering a child. While many Wilms tumor survivors have normal reproductive function, certain treatments may increase infertility risk. Fertility preservation, monitoring, and specialist support can help address reproductive health concerns.

 

Leydig Cell Function

Leydig cells are specialized cells within the testes that produce testosterone. Cancer treatment can occasionally affect Leydig cell function, potentially influencing puberty, hormone production, and reproductive health. Endocrine testing may be used to evaluate testicular hormone function when concerns arise.

 

Luteinizing Hormone (LH)

Luteinizing Hormone (LH) is a hormone involved in puberty, reproductive development, and fertility. LH testing is commonly performed during endocrine evaluations and helps assess ovarian and testicular function.

 

Menstrual Health

Menstrual health refers to the normal functioning of the menstrual cycle and reproductive system. Female childhood cancer survivors may undergo monitoring of menstrual health if treatments received carry potential reproductive or endocrine risks.

 

Ovarian Function

Ovarian function refers to the ability of the ovaries to produce hormones and release eggs. Certain cancer treatments may affect ovarian function and future fertility. Monitoring ovarian health is an important component of reproductive survivorship care.

 

Ovarian Reserve

Ovarian reserve refers to the number and quality of eggs remaining within the ovaries. Assessments of ovarian reserve may help estimate future fertility potential in female cancer survivors and guide reproductive planning discussions.

 

Pediatric Endocrinology

Pediatric endocrinology is the medical specialty focused on hormone-related conditions affecting children and adolescents. Pediatric endocrinologists frequently participate in the long-term care of childhood cancer survivors with growth, puberty, fertility, or endocrine concerns.

 

Precocious Puberty

Precocious puberty occurs when puberty begins earlier than expected. Although uncommon, certain medical conditions and treatments may influence the timing of pubertal development. Early evaluation helps ensure appropriate management and support.

 

Pubertal Development

Pubertal development refers to the physical and hormonal changes that occur as children mature into adolescence. Survivorship programs often monitor pubertal development to identify potential endocrine or reproductive health concerns related to previous cancer treatment.

 

Reproductive Health

Reproductive health encompasses fertility, hormone production, sexual development, and overall reproductive well-being. Childhood cancer survivorship programs increasingly recognize reproductive health as an important component of long-term quality of life.

 

Sperm Banking

Sperm banking is a fertility preservation method in which sperm is collected and frozen for future use. This option may be available for some adolescent males before treatment begins when therapies carry potential fertility risks.

 

Testicular Function

Testicular function refers to the testes' ability to produce sperm and hormones such as testosterone. Monitoring testicular function may be important for male survivors who received treatments associated with reproductive risks.

 

Testicular Failure

Testicular failure occurs when the testes are unable to produce adequate levels of testosterone, sperm, or both. Testicular failure may affect puberty, fertility, sexual health, and overall well-being. Endocrinologists and fertility specialists can provide evaluation and management when needed.

 

Testosterone

Testosterone is the primary male sex hormone and plays a critical role in puberty, fertility, muscle development, bone health, and overall well-being. Low testosterone levels may occur when testicular function is impaired and can often be managed through medical treatment.

 

Thyroid Function

Thyroid function refers to the activity of the thyroid gland, which regulates metabolism, growth, energy levels, and many other bodily processes. Thyroid monitoring may be included in survivorship care when treatment-related endocrine risks are present.

 

Survivorship Fertility Monitoring

Survivorship fertility monitoring refers to the ongoing evaluation of reproductive health following childhood cancer treatment. Monitoring may include hormone testing, fertility assessments, endocrine evaluations, and specialist consultations designed to identify concerns early and support future family planning.

 

Wilms Tumor Survivorship Endocrine Care

Wilms Tumor Survivorship Endocrine Care involves the long-term monitoring and management of hormone-related health issues that may develop following treatment. This may include growth assessments, puberty evaluations, fertility monitoring, thyroid function testing, and reproductive health support to help survivors maintain lifelong health and quality of life.

Understanding the medical terms

Some treatments used for Wilms tumor may affect fertility, hormone production, growth, or pubertal development, making long-term endocrine monitoring and survivorship follow-up an important part of lifelong care.
