The Correct Option is A
Solution and Explanation
Sertoli cells are the cells that line the seminiferous tubules in the testis. These cells protect the spermatids and convey nutrients to both the developing and mature Spermatozoa. Sertoli cells are regulated by $FSH$ (Follicle Stimulating Hormone) as the $FSH$ receptors are confined to the sertoli cells.
$FSH$ stimulates sertoli cells to produce) androgen-binding protein and inhibin; and together with testosterone, promotes the proliferation of Sertoli cells.
Growth Hormone $(GH)$ or Somatotropin $(STH)$ is secreted from adenohypophysis of pituitary gland. It stimulates cellular growth and proliferation, growth and repair of bones, I muscles and connective tissue. In the liver cells it promotes, glycogenesis, deamination I and glycogenesis. Prolactin $(PRL),|$ Lactogenic, Luteotropic $(LTH)$
or Mammotropic Hormone $(MTH)$ is secreted by the lactotroph cells of anterior pituitary. In humans, it may act as a mild growth hormone, but its main physiological effect is to activate growth of breasts during pregnancy and secretion of milk by mammary glands after child birth.
Luteinizing Hormone $(LH)$ or. Interstitial Cells to stimulating hormone $(ICSH)$ is secreted from adenohypophysis of pituitary gland. In man, it stimulates the growth and function of the interstitial cells of testes (Leydig cells), which secrete the male hormone (androgens) to regulate the development of secondary sexual characters. In women, it stimulates the last stages of oogenesis, ovulation, development of corpus luteum and secretion of progesterone by the corpus luteum.

Concepts Used:
Human Reproduction
Reproduction in human beings involves the fusion of male and female gametes that produces in their reproductive system.
Male 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.
Female Reproductive System:
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.
