The question focuses on identifying the gland present in females among the given options.

Selecting from the choices, the Bartholin's Gland is found in females, specifically at each side of the vaginal opening.

This gland secretes fluid that aids in vaginal lubrication. Hence, the correct answer is D, "Bartholin's Gland".

This question requires an understanding of the dimensions of the ovaries, part of the female reproductive system.

From the choices provided, the typical length of an ovary is about 5 cm.

Therefore, the correct answer is C, "5 cm".

This question centers on the hormonal output of Sertoli cells, which play key roles in male reproductive physiology.

Among the options, Sertoli cells are known to produce Inhibin, which helps regulate spermatogenesis.

So, the correct answer is C, "Inhibin".

This question is based on understanding the process of spermatogenesis, specifically the number of sperm cells produced from one primary spermatocyte.

Among the choices provided, a single primary spermatocyte gives rise to four sperms.

Therefore, the correct answer is B, "Four Sperms".

The question revolves around identifying the cells that produce Testosterone, a vital male sex hormone.

Of the options given, Leydig cells, located between seminiferous tubules, are responsible for the production of Testosterone.

Thus, the correct choice is B, "Leydig Cells".

The question pertains to the location of the formation of the corpus luteum, a glandular structure in the female reproductive system.

Considering the choices, the corpus luteum is formed at the site of ovulation.

Hence, the correct answer is B, "Ovulation".

The question is about the dimensions of the Epididymis, a structure in the male reproductive system.

The Epididymis, situated on the backside of each testis, primarily consists of a highly coiled duct, which, when uncoiled, measures approximately 20 feet.

Therefore, the correct answer is B, "20 Feet".

This question requires identifying the duct in the male reproductive system that extends into the pelvic cavity and merges with the seminal vesicles.

Among the options, the Vas Deferens is the duct that starts from the Epididymis, goes deep into the pelvic cavity, and joins the seminal vesicles to form the ejaculatory duct.

Thus, the correct answer is B, "Vas Deferens".

The question revolves around the specific location within the female reproductive system where ovum fertilization usually occurs.

Of the given options, the upper third of the oviduct is where the ovum is typically fertilized.

Hence, the correct answer is A, "In the upper third of the oviduct".

The question pertains to the specific site of embryo implantation within the uterus.

The given options list various parts of the uterus, but the embryo implants in the endometrium, the inner lining.

Thus, the correct answer is C, "Endometrium".

The question aims to contrast the processes of spermatogenesis and oogenesis.

Among the provided choices, the fundamental difference lies in the number of mature cells produced: oogenesis yields one mature ovum, whereas spermatogenesis generates four mature sperms.

Hence, the correct answer is D, "Oogenesis results in one mature ovum, while spermatogenesis produces four mature sperms".

This question deals with the composition of the uterine wall.
