Neisseria Gonorrhea is the bacterium that causes gonorrhea.

Therefore, the correct answer is B, "Neisseria Gonorrhea".

Syphilis is caused by the bacterium Treponema pallidum.

Therefore, the correct answer is D, "None".

The question pertains to the average length of the oviduct, a component of the female reproductive system.

Among the given options, the average length of the oviduct is approximately 10 cm, which invalidates options A, B, and D.

Therefore, the correct answer is C, "10 cm".

This question aims to identify the specific hormone secreted by Leydig cells.

Testosterone is the hormone secreted by Leydig cells, ruling out options A, C, and D.

Therefore, the correct answer is B, "Testosterone".

This question tests your knowledge about the gland or cell type that produces the hormone Inhibin.

From the options provided, Inhibin is produced by Sertoli cells, making options A, B, and C incorrect.

Therefore, the correct answer is D, "Sertoli cells".

You're tasked with finding the approximate percentage of double ovulation events in human females from the options given.

The correct answer is C, "1-2%", indicating that double ovulation occurs in 1-2% of ovulation cases, thus negating options A, B, and D.

Therefore, the correct answer is C, "1-2%".

This question aims to determine which hormone, among the listed options, leads to the enlargement of uterine glands.

It is Progesterone that causes the uterine glands to enlarge, thereby eliminating options A, C, and D.

Therefore, the correct answer is B, "Progesterone".

This question examines your understanding of the effect of the Follicle-Stimulating Hormone (FSH) secreted by the pituitary gland.

The answer choice C, "Follicle," is the target of FSH, which stimulates its growth. Therefore, options A, B, and D are incorrect.

Therefore, the correct answer is C, "Follicle".

The question aims to identify the disease caused by a virus from the given options.

Of the listed diseases, only Herpes is caused by a virus; thus, Syphilis and Gonorrhea (caused by bacteria) are not valid answers, negating options A, C, and D.

Therefore, the correct answer is B, "Herpes".

This question asks you to identify the global annual mortality rate due to AIDS from the provided options.

The correct answer is B, "Two million," which indicates that the annual mortality rate due to AIDS worldwide surpasses this number. Therefore, options A, C, and D are not correct.

Therefore, the correct answer is B, "Two million".

This question is probing your understanding of where the process of spermatogenesis takes place.

Of all the provided options, the process of spermatogenesis precisely occurs in the Seminiferous tubule, thereby making options A, B, and D incorrect.

Thus, the correct answer is C, "Seminiferous tubule".

The question seeks to evaluate your knowledge about which gland or organ secretes Hyaluronidase.

From the options, Hyaluronidase is primarily secreted by the Prostate gland, hence ruling out options B, C, and D.

Therefore, the correct answer is A, "Prostate gland".

The question is designed to test your understanding of the specific type of defense cell that the HIV virus primarily targets and destroys.

Of the choices provided, HIV primarily attacks and destroys CD4 cells, thereby making A, B, and C incorrect.

As a result, the correct answer is D, "CD4".

The question is pinpointing your knowledge on the specific phase of the menstrual cycle when the Corpus luteum is most active.

Among the options, the Corpus luteum is primarily active during the Post ovulatory phase, hence options A, B, and D are incorrect.

Thus, the correct answer is C, "Post ovulatory phase".

The question seeks to test your understanding of which hormone influences the secretion of Testosterone.

The ICSH (Interstitial Cell-Stimulating Hormone) from the pituitary gland acts on the Leydig cells to produce Testosterone, eliminating options A, C, and D.

Hence, the correct answer is B, "ICSH (Interstitial Cell-Stimulating Hormone)".

The question aims to evaluate your knowledge on the composition of semen.

Among the provided options, only Prostaglandin is found in semen, negating options B, C, and D.

Therefore, the correct answer is A, "Prostaglandin".

Ascorbic acid is predominantly found in the secretion of the Seminal vesicle.

Therefore, the correct answer is C, "Seminal Vesicle".

The Ejaculatory duct is formed when the Vas deferens joins the seminal vesicle duct.

Thus, the correct answer is B, "Ejaculatory duct".

A secondary spermatocyte is produced after Meiosis I during spermatogenesis.

Therefore, the correct answer is A, "Meiosis I".

Oogenesis starts and then halts for a significant amount of time during Prophase 1.

Thus, the correct answer is A, "Prophase 1".

Sex hormones are produced by both the Gonads and the Adrenal cortex.

Therefore, the correct answer is C, "Both Gonads and Adrenal cortex".

The Vasa efferentia ultimately deliver the sperm into the Epididymis.

Thus, the correct answer is B, "Epididymis".
