Question

Cryptorchidism is a condition, in which testes
(A) Unable to descend in scrotal sacs
(B) Unable to produce sperms
(C) Having been surgically removed
(D) Having remained undeveloped

Answer 1

In human males, the testes are situated in a pouch called the scrotum and during the seventh month of pregnancy in the intra-uterine development they start descending in the scrotal sac.

Step by step answer: A condition within which one or each of the testes or both fail to descend from the abdomen into the pouch is termed Cryptorchidism. During embryonic life, the testes develop at intervals in the abdomen; however, they descend into the scrotal pouch before birth.
-If they fail to do so and if this condition isn't corrected it results in infertility and therefore the risk of carcinoma is enhanced. Undescended testis leads to this condition called cryptorchidism which is abnormal.
-Factors that may increase the chance of cryptorchidism during a newborn include Low birth weight, premature birth, family history of Undescended testicles or different issues of sex organ development, conditions of the fetus which can prohibit growth, like {down syndrome, mongolism, mongolianism, birth defect, congenital disorder, congenital abnormality, retardation, mental retardation, backwardness, slowness, sub normality} or another defect. Alcohol use by the mother throughout physiological pregnancy condition If Cigarette smoking is done by the mother or exposure to any second-hand smoke can cause Cryptorchidism. Parents' exposure to some pesticides.
-The inability to produce sperm is called Azoospermia. A lack of spermatocytes within the ejaculate is due to blockage of the male reproductive system (obstructive azoospermia) with utterly traditional gamete production or the results of poor gamete production (nonobstructive azoospermia), that interferes with the assembly of gamete.
-Orchiectomy is the surgical process to remove testes. This is generally done when the patient is suffering from testicular cancer. The main causes of removal of testes is torsion $\left( 45.8\% \right)$, cryptorchidy $\left( 32.5 \% \right)$ and sex gland tumor $\left( 16.9\% \right)$ within the patients aged 0-25 years, sex gland tumour $\left( 42.4\% \right)$, cryptorchidy $\left( 25.9\% \right)$ and TB $\left( 10.6\% \right)$ in those aged 26-50 years.
Hence, A is the correct option.

Note: About three- of full-term and thirty percent of newborn infant boys are born with this disorder. However, concerns about the rest eightieth percent of cryptorchid testes descend by the primary year of life (the majority at intervals 3 months), creating an actual incidence of cryptorchidism around 1 Chronicle overall.
