The correct option is D Orchidopexy
Infertility is a condition which prevents natural conception in couples who perform regular acts of unprotected coitus. Infertility could result from various reasons and due to either of the male or female partner or even both. In this question, we are discussing about male infertility. Male infertility could be caused due to a variety of reasons- cryptorchidism, erectile dysfunction, hormonal imbalances, chromosomal defects and various other reasons.
Cryptorchidism refers to a condition in which the testes fail to move down into the scrotum from the abdominal cavity. The problem with this condition is that the testes require a lower temperature (2-2.5 degree celsius lower) than the body temperature for the process of spermatogenesis (sperm formation) to occur. This decrease in temperature can be provided in the scrotum. Since the testes haven’t descended down and continue to remain in the abdominal cavity, they are exposed to the body temperature. Also, the normal growth is hindered.
Orchidopexy is a surgical procedure which is performed to correct cryptorchidism. Hence, this can help overcome the problems of male sterility.
Orchidectomy refers to the surgical removal of the testes. If testes are removed, there would be permanent infertility.
Decrease in blood supply to the penis would hinder it from achieving and maintaining a firm erection for proper sexual intercourse. If this condition persists for a long time, it could result in infertility.
Anabolic steroids are certain chemicals or drugs. If they are taken, they could decrease the gonadotropin release in the body. Gonadotropins are hormones released by the anterior pituitary which help in the formation of gametes and sex hormones in both males and females. If release of gonadotropins is decreased or inhibited, it could lead to infertility.
