Choose the common characteristics of the male and female reproductive systems:

They produce reproductive cells called gametes, They contains ducts which receive and transport gametes, They contain glands and accessory organs which secrete fluids (subsequently carried through the ducts), They include external genitalia (such as the vulva in women or the penis in men)

Choose the true statement(s) referring to the male reproductive system:

It is responsible for producing, storing, maintaining and transporting spermatozoa, It is responsible for producing, storing, maintaining and transporting male gametes, Have several structures similar to those of the female reproductive system: gonads, ducts, glands and accessory organs of the reproductive process

Choose the true statement(s) referring to the male reproductive system:

Its reproductive cells are called gametes, It is responsible for producing, storing, maintaining and transporting gametes, It consists of glands and accessory organs (the prostate, seminal vesicles)

Choose the true statement(s) referring to the male reproductive system:

It comprises gonads, ducts, glands and accessory organs, It comprises ducts, external genitalia, accessory organs and glands associated with the reproductive process, Testicles, also called male gonads, produce gametes and hormones

Which of the following statements referring to the male reproductive system are true?

Its reproductive cells are called gametes, just like those of the female reproductive system, It is responsible for producing, storing, maintaining and transporting male reproductive cells, The system has ducts which receive and transport reproductive cells, The system has accessory glands which secrete fluids that are transported through ducts

Choose the true statement(s) referring to the testicle:

It lies in the scrotum, a sac-like structure suspended under the perineum, It is an oval, flattened organ, Its function is to produce sex hormones (testosterone) and reproductive cells (spermatozoa)

Which of the following statements referring to the development of the testicles are true?

During the foetal phase, testicles develop in the abdominal cavity, near the kidney, and they descend to the scrotum until the 7th month of pregnancy, Cryptorchidism may lead to infertility and requires surgical intervention, The temperature inside the abdominal cavity, a few degrees higher than that in the scrotum, prevents the normal process of spermatogenesis, which is why testicles need to descend in the scrotum

Choose the correct definitions from below:

Cryptorchidism – disorder where testicles are prevented from descending into the scrotum, The spermatic cord – a structure consisting of the ductus deferens, blood vessels and nerves, The gubernaculum – a ligament of fibrous tissue, responsible with guiding the descent of the testicles into the scrotum

Choose the true statements:

The spermatic cord consists of blood vessels, nerves and the ductus deferens, The area of the inguinal canal is a low-resistance point in the abdominal wall thus facilitating the development of inguinal hernias, Hernias represent the protrusion of any abdominal structure through the abdominal wall

Choose the true statements referring to the scrotum:

It is a structure with multistratified walls which houses the testicles, It is divided into two compartments separated by a thickened ridge, The two compartments are delimited by the perineal raphe

Choose the true statements referring to the seminiferous tubules:

The germinal cells of the seminiferous tubules produce spermatozoa – the male sexual cells, The interstitial cells located outside the seminiferous tubules secrete androgenic hormones (mainly testosterone)

Choose the true statements referring to the testicular network (rete testis):

It is a plexus resulting from interconnecting seminiferous (convoluted) tubules, It is drained by the efferent channels which subsequently enter the epididymis, It is drained by several efferent channels which originate in the superior part of the testes

Choose the correct associations from below:

Scrotum – two compartment – the dartos muscle, Scrotum – one compartment for each testicle – perineal raphe, Inguinal canal – low resistance point of the anterior abdominal wall – inguinal hernia

Which of the following statements are true?

The seminal fluid adapts its composition according to the secretions or the cells lining the epididymis, The pH of the seminal fluid is acid due to the degradation products of stored sperm, Spermatozoa gain mobility in the epididymis in approximately two weeks

The following statement(s) is/are true about the epididymis:

It is the site of reabsorption for deteriorated spermatozoa and for residues, In it, spermatozoa become mobile in approximately two weeks, After leaving it, spermatozoa pass into the ductus deferens (vas deferens)

The following statement(s) is/are true about the accessory organs of the male reproductive system:

They are organs that participate in sperm transportation during copulation, The seminal vesicle is a paired organ and secretes prostaglandins (hormonal substances), The prostate, also called prostate gland, is an unpaired organ which secretes an alkaline fluid

Choose the true statements referring to spermatogenesis:

It is the process by which male gametes are produced, It begins in the outermost layer of the germinal cells in the seminiferous tubules, The cells resulting from this process are called spermatozoa

Choose the true statements referring to primary spermatocytes:

They result from the mitotic division of spermatogonia, They are diploid cells (2n), their nucleus containing 46 chromosomes per cell, They develop in the convoluted seminiferous tubules and they are moved to the inner regions of the latter

Which of the following statements referring to spermatozoa are true?

They are the result of the process of spermatogenesis, They are also called male reproductive cells or male gametes

Choose the true statements referring to the male gametes:

They are also called male sexual cells or spermatozoa, They develop in the lobules of testis, in the convoluted seminiferous tubules, The head, neck, middle piece and tail are parts of the spermatozoon

Choose the effects of testosterone:

It stimulates the metabolic processes that increase muscle mass, It ensures the proper functioning of the male reproductive system after puberty, It stimulates the development of male secondary sexual characteristics after puberty

Choose the true statements from below:

The follicle stimulating hormone FSH induces spermatogenesis, Testosterone induces spermatozoa maturation after puberty, In the foetus, testosterone contributes to the descent of the testes into the scrotum

Choose the true statements referring to testosterone and its effects:

It is a steroid hormone, It is produced in small amounts until puberty, After puberty, it stimulates the metabolic processes connected to protein synthesis

Which of the following statements are false?

During erection, the prostate’s erectile tissue fills with blood, The membranous urethra passes through the middle of the prostate and receives its secretions

About the ejaculate, it is true that:

It contains spermatozoa (20-100 million/ml semen), Its volume is normally of 2-5 ml, It contains lubricating mucus, secreted by the bulbourethral glands
