These cells are found in small groups within the interstitial fluid present between the seminiferous tubules.

This enzyme is present in many androgen-responsive tissues, including the prostate, skin, and sebaceous glands.

This plasma protein also binds other sex hormones such as oestrogens and progestogens.

This binding protein is more selective compared to the one found in the bloodstream.

This hormone is synthesized from cholesterol early on in the pathway.

This enzyme is found in some tissues and converts testosterone to a hormone that is particularly important in females but also has effects in males.

This hormone is a potent androgen in its own right and can be converted to an even more powerful androgen by the enzyme 5α-reductase.

This hormone binds to its receptors in the Sertoli cells and induces activities necessary for the spermatogenic process.

This enzyme converts testosterone to oestrogens in Sertoli cells.

These glands contribute to the seminal fluid by providing nutrients and fluid volume.

This hormone is released by the anterior pituitary and is involved in stimulating androgen production.

This hormone is responsible for the development of specific characteristics in males during adolescence.

This hormone is produced by Sertoli cells and is involved in the regulation of the hypothalamo-adenohypophysial axis.

In this part of the male reproductive system, spermatozoa undergo a process involving water reabsorption.

This gland contributes about 60% of the total volume of human semen.

Androgens are considered anabolic steroids and play a role in a specific type of metabolism.

This hormone is an androgen that plays a role in the production of a specific hormone that influences erythrocyte proliferation.

These cells are found in the male reproductive system and are involved in the synthesis of inhibin in response to FSH.

This hormone is released from the anterior pituitary gland and influences Leydig cells in the testes to produce androgens.

Androgens have an effect on sebaceous glands and can lead to a common skin problem in adolescents.

These glycoproteins are produced by gonadotrophs and folliculostellate cells and have a blocking effect on activin molecules.

This hormone is produced by the anterior pituitary gland and acts on the Sertoli cells in the testes.

This growth spurt is due to the combined action of an androgen and another hormone that influences growth.

These factors are related to the senses and play a key role in penile erection.

This neurotransmitter is released by parasympathetic nerve fibers and is involved in the vasodilation process.

This drug is also known as Viagra and is a popular treatment for erectile dysfunction.

This syndrome is characterized by an extra chromosome (47 XXY) and is associated with small testes, azoospermia, and gynecomastia.

This artery runs along the length of the penis and is separate from the main structure responsible for an erection.

This structure is a venous sinusoidal space that surrounds the urethra and has a spongy appearance.

Impotence is a result of a failure to achieve a specific penile state.

This phase of sleep is associated with dreaming and is characterized by rapid eye movements.

This condition is caused by a genetic defect in the X-chromosome and affects the way the body responds to testosterone.

This condition typically affects males between the ages of 19 and 35 and can cause fever, tenderness, and pain in the scrotum.

This condition causes a soft, non-tender and cystic swelling in the scrotum and the testis cannot be palpated due to the fluid collection.

These tumors often originate from germ cells and are more prevalent in younger adult males.

This condition can cause a 'bag of worms' feeling and is related to the pressure in the renal veins.

This condition often presents with acute pain and can lead to testicular infarction if not treated promptly.

This histopathological finding is specific to a chromosomal disorder affecting males.

These two functions are essential for the procreation of the species.

One type of cycle is found in rodents, while the other is found in primates.

This axis involves the hypothalamus, the anterior pituitary, and the ovaries.

Oestrogens have a beneficial effect on the cardiovascular system by influencing lipoprotein cholesterol.

Oestrogens have an effect on protein synthesis, especially during puberty.

Oestrogens have an effect on the endometrium during the proliferative phase of the endometrial cycle.

Oestrogens have an effect on cervical secretion during the follicular phase of the ovarian cycle.

Excessive gonadal steroids during puberty affect skeletal maturity and final height.

Oestrogens have an effect on renal sodium reabsorption.

Oestrogens affect calcium absorption in the gastrointestinal system.

Oestrogens have central effects on behavior.

Breast tissue development is influenced by hormones, with one playing a key role in ductile growth.

HDL has a specific role in cholesterol redistribution under the influence of oestrogens.

Menopause and decreased oestrogen levels have an impact on coronary artery disease risk.

Oestrogens have an effect on bone mineralisation through their actions on osteoblasts and osteoclasts.

Progesterone synthesis is linked to a specific phase of the ovarian cycle.

Progesterone has a specific function in the endometrium during the secretory phase.

One of the options is an estrogen, not a progestogen.

The majority of progesterone is bound to a specific plasma protein.
