Reproductive-cell cycle theory

Index Reproductive-cell cycle theory

Rather than seeing aging as a loss of functionality as we get older, this theory defines aging as any change in an organism over time, as evidenced by the fact that if all chemical reactions in the body were stopped, no change, and thus no aging, would occur. [1]

Alzheimer's disease

Alzheimer's disease (AD), also referred to simply as Alzheimer's, is a chronic neurodegenerative disease that usually starts slowly and worsens over time.

Calorie restriction

Calorie restriction, or caloric restriction, or energy restriction, is a dietary regimen that reduces calorie intake without incurring malnutrition or a reduction in essential nutrients.

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.

Dementia

Dementia is a broad category of brain diseases that cause a long-term and often gradual decrease in the ability to think and remember that is great enough to affect a person's daily functioning.

Endocrinology of reproduction

Hormonal regulation occurs at every stage of development.

Fertility

Fertility is the natural capability to produce offspring.

Germ cell

A germ cell is any biological cell that gives rise to the gametes of an organism that reproduces sexually.

Hypothalamic–pituitary–gonadal axis

The hypothalamic–pituitary–gonadal axis (HPG axis) refers to the hypothalamus, pituitary gland, and gonadal glands as if these individual endocrine glands were a single entity.

Menopause

Menopause, also known as the climacteric, is the time in most women's lives when menstrual periods stop permanently, and they are no longer able to bear children.

Osteoporosis

Osteoporosis is a disease where increased bone weakness increases the risk of a broken bone.

Postmenopausal hormone therapy

Menopausal hormone therapy (MHT), or postmenopausal hormone therapy (PHT, PMHT), also known as hormone replacement therapy in menopause, is a form of hormone replacement therapy (HRT) which is used in postmenopausal, perimenopausal, and surgically menopausal women.

Senescence

Senescence or biological ageing is the gradual deterioration of function characteristic of most complex lifeforms, arguably found in all biological kingdoms, that on the level of the organism increases mortality after maturation.

Stroke

A stroke is a medical condition in which poor blood flow to the brain results in cell death.
