Reproductive system question and answer
Male & female reproductive system | neet biology mcqs
These are male reproductive glands that are about 4.5cm long, 3.5cm high, and 3cm thick and are suspended in the scrotum, similar to female ovaries. The testes are covered by three layers of tissue: the outer tunica vaginalis, the middle fibrous tunica albuginea, and the inner tunica vasculosa, which is made up of capillaries.
The testes are suspended in the scrotum by the spermatic cords. The testicular artery, veins, lymphatic vessels, and nerves are all found in each cord. The cord is protected by a layer of smooth muscle, connective tissue, and fibrous tissue, and it extends across the inguinal canal to the testes on the posterior wall.
There are two small pouches of fibrous tissue and smooth muscle on the bladder’s posterior side that are around 5cm long. Each vesicle opens into a short duct at its lower end, which joins with the deferent duct to form the ejaculatory duct.
The ejaculatory ducts are two tubes that are about 2cm long and are made up of seminal vesicles and deferent ducts (ductus deferens). They travel from the prostate gland to the urethra, carrying seminal fluid and spermatozoa. Smooth muscle and fibrous tissue make up their walls.

Anabolic steroids (synthetic testosterone) bulk up muscles, but they also impair testosterone output in the testis. Describe what will happen to testosterone output in the testis if a male took massive quantities of synthetic testosterone, using what you know about negative feedback.
Endometriosis is a disease in which endometrial cells expand and implant outside of the uterus, such as in the uterine tubes, the ovaries, or the pelvic cavity. Give an explanation for why endometriosis increases a woman’s infertility danger.
When a boy or girl reaches puberty, the hypothalamus, pituitary, and gonads undergo changes in sensitivity. Explain how these modifications involve a rise in the release of sex steroid hormones, which is responsible for many pubertal changes.

Answer: The primordial follicle is surrounded by flattened, squamous epithelial cells with no zona pellucidum. There is a prominent zona pellucidum and a single layer of cuboidal granulosa cells in the primary follicle.
Answer: The granulosa cells, in collaboration with a population of modified stromal cells known as the theca interna, will begin developing estrogens after being stimulated by both FSH and luteinizing hormone (LH).
Response 9: The fully mature Graafian follicle has a large antrum filled with liquor folliculi and a cumulus oophorus containing an oocyte within a set of granulosa cells. The corona radiata is made up of granulosa cells that cover the oocyte.
Answer 10: Elevated estrogen levels cause an increase in LH, which activates the completion of meiosis I and the ovulation process. Just one of the antral follicles in the cohort is usually ovulated.
Response 12: After ovulation, the follicle remnant will be transformed into a corpus luteum (CL). There are two types of lutein in this: granulosa lutein and theca lutein. These cells will be stimulated to develop progesterone by residual LH (and some estrogen).
Male & female reproductive system | important questions
The epididymis stores and matures sperm cells until they are transported to the urethra through the vas deferens. Sperm is formed in the testes, while fluids are produced in the seminal vesicles and later incorporated into semen.
Explanation: As sperm are released, seminal vesicles secrete seminal fluid to encourage and nourish them. A part of seminal fluid is secreted by the bulbourethral glands, while alkaline fluid is secreted by the prostate gland.
The ovaries are where ovum is made. The fallopian tubes use cilia movement to propel the ovum to the uterus after it is formed. The endometrium is the uterine lining that enables a fertilized ovum to be implanted.
Explanation: Fertilization takes place in the female’s fallopian tubes in the vast majority of cases. During ovulation, the egg is released from the ovary and moves into the fallopian tube. The zygote is created when sperm move to the fallopian tube and fertilize the egg. Before reaching the uterus, the zygote divides and forms a blastocyst, which is then inserted into the endometrium through the implantation method. If the blastocyst implants while still in the fallopian tube, it may cause ectopic pregnancy and other pregnancy complications.
