Choose the most accurate statement for spermatogenesis and oogenesis.Pilih kenyataan yang paling tepat mengenai spermatogenesis dan oogenesis.A. A sperm cell is larger than an ovum.B. Spermatogenesis occurs in the ovary, while oogenesis occurs in the testis.C. Spermatogenesis is a lifelong process, while oogenesis will stop atmenopause.D. A spermatogonium develops into secondary spermatocytes, while anoogonium develops into a secondary oocyte.
How do tubal ligations and vasectomies prevent further pregnancies?
Select one:
a. The corpus luteum and the epididymis are suppressed using a chemical swab. The fertilized egg could no longer implant in the endometrium.
b. The Fallopian tubes and vas deferens are cut and tied off, thereby preventing the movement of the eggs and sperm.
c. The Fallopian tubes and the vas deferens are cut. Eggs and sperm can no longer be produced.
d. The Fallopian tube and vas deferens are cut and tied off, thereby reducing needed reproductive hormone levels.
