The Correct Option is A

To identify the statements that are true for spermatogenesis but not for oogenesis, let's analyze each statement one by one:

It results in the formation of haploid gametes: True for both spermatogenesis and oogenesis, as both processes produce haploid gametes (sperm and eggs, respectively), hence not exclusive to spermatogenesis.
Differentiation of gamete occurs after the completion of meiosis: In spermatogenesis, sperm differentiation occurs after meiosis forms spermatids. In oogenesis, meiosis produces a mature egg directly during ovulation. Hence, this does not exclusively apply to spermatogenesis.
Meiosis occurs continuously in a mitotically dividing stem cell population: In spermatogenesis, sperm production is continuous and meiosis occurs uninterrupted in a mitotically active stem cell population (spermatogonia) throughout life after puberty. In oogenesis, meiosis is arrested at certain stages until fertilization. This statement is exclusive to spermatogenesis.
It is controlled by the Luteinizing hormone (LH) and Follicle Stimulating Hormone (FSH) secreted by the anterior pituitary: Both spermatogenesis and oogenesis are regulated by LH and FSH, thus not exclusive to spermatogenesis.
It is initiated at puberty: Spermatogenesis begins at puberty, while oogenesis begins before birth and resumes at puberty, making this initiation at puberty aspect specific to spermatogenesis.

From the analysis:

Thus, the correct choice is: (c) and (e) only.

Reproduction in human beings involves the fusion of male and female gametes that produces in their reproductive system.

The male reproductive system comprises:

Testicles (testes): A pair of oval-shaped organs masked in a pouch known as the scrotum. They manage the production of sperms and the male hormone testosterone.
Scrotum: It is a sac-like organ that hangs under the penis and behind it. It is the house of the testes, or testicles, and maintains a temperature that is needed for the production of sperm by it.
Vas deferens: The sperms produced in testes are stored in a tube known as the epididymis. Here the sperms get matured and pass to the urethra via the muscular tube known as vas deferens.
Accessory glands: This includes three glands, namely the prostate gland, seminal vesicles, and Cowper’s gland. The secretions from the mentioned three glands mix to form a fluid known as semen. Semen nourishes the sperm, raises the volume, and helps in lubrication.
Penis: The penis is a cylindrical tube that serves as both an excretory organ, and a reproductive organ. It transfers sperms into the vagina during sexual intercourse.

The female reproductive system is active before, during, and after fertilization as well. It comprises the following parts:

A pair of ovaries: A pair of ovaries produce and stores ovum in them. They also produce a female hormone known to be estrogen.
Fallopian tubes (Oviducts): They are the area of fertilization. They connect both the ovaries with the uterus.
Uterus: Uterus is the place of development for the embryo.
Vagina: The part that connects the cervix to the external female body parts is called a vagina. It is the passage for the penis during coitus as well as a fetus during transfer.
