FSH stimulates ovarian follicle to secrete oestrogen and adrenal gland to secrete androgens. Sex steroid causes secondary sexual characteristics of puberty. Sperms develop from spermatogonia mature into primary spermatocytes. Secondary spermatocytes form after first meiotic division of the primary spermatocytes. Secondary spermatocytes undergo second meiotic division to spermatids. Both divisions take place in the seminiferous tubules after which spermatids migrate to the sertoli cells (McLafferty et al., 38). Maturation of spermatids into spermatozoa involves leydig cells that produce GnRH, LH (ICSH), DHT, testosterone, ABP, and inhibin that regulate spermatogenesis. The epididymis stores mature sperms. Upon sufficient stimulation, spermatozoa move through vas deferens, ampulla, ejaculatory duct , urethra then outside the body. The tubular pathway contracts to propel the ejaculate.

This total irrelevancy of policies that these institutions advocate for developing countries is nothing new even in respect of those East Asian economies like South Korea and Taiwan. However these latter countries could successfully ignore the Washington dictated reformist formula and achieve a greater degree of equality among their citizens. Globalization and/or globalism particularly refer to a set of liberal economic principles that underlie the very nature of how best to expand international trade and commerce links beyond the national borders of countries (Nagdeman, 2009).
