Hypothalamic-pituitary-testicular axis is a hormone pathway responsible for regulating the production of testosterone in males. The hypothalamus secretes gonadotropin-releasing hormone (GnRH) which stimulates the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones then act on the testes to produce testosterone and regulate sperm production.
Also known as the hypothalamic-pituitary-adrenal axis, this is by which adrenal stimulation of cortisol production (by pituitary ACTH release).

No, the thalamus is not part of the brain-testicular axis. The brain-testicular axis typically involves communication between the hypothalamus, pituitary gland, and testes to regulate hormone production and reproductive functions. The thalamus is mainly involved in relaying sensory and motor signals to the cerebral cortex.
The hypothalamic-pituitary-adrenal (HPA) axis combines the actions of the hypothalamus, pituitary gland, and adrenal gland to regulate stress response and hormone production.
The hypothalamic-pituitary-gonadal axis (also HPG axis) is referring to the effects of the hypothalamus, pituitary gland, and gonads as if these individual endocrine glands were a single entity as a whole. Because these glands often behave in cooperation, physiologists and endocrinologists find it convenient and descriptive to speak of them as a single system.The hypothalamic-pituitary-gonadal axis is a critical part in the development and regulation of a number of the body's systems, such as the reproductive, and immune systems. Fluctuations in the hormones cause changes in the hormones produced by each gland and have various widespread and local effects on the body. This axis controls development, reproduction, and aging in animals. The hypothalamus produces gonadotropin-releasing hormone (GnRH). The anterior portion of the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and the gonads produce estrogen and testosterone.
Basically, the hypothalamic-hypophyseal tract is the axon connection that connects the posterior pituitary gland to the hypothalamus

Hypothalamus, it links the nervous system to the endocrine system via the pituitary gland (hypophysis). P.S. - It secretes hypothalamic tropic factors (hypothalamic hormones - neurohormones, often called hypothalamic-releasing hormones) to the anterior lobe of the pituitary gland by way of a special capillary system, called the hypothalamic-hypophysial portal system.(Courtesy: Wikipedia - the free encyclopedia)
An Endocrine Axis is a specific network composed of the set of neurons that complete an entire hormonal cycle (I.E. the hypothalamus takes up dopamine--which is produced in the liver-- in the form of L-Dopa and reconverts it into Dopamine which is then be released into the hypothalamic-pituitary Axis and inhibits the release hormones like prolactin.) In this case the hypothalamus and the pituitary form an axis with respect to the trajectory of effect of Dopamine. Hope this gives you an idea.
