Taurus – Physical – Root: REPRODUCTIVE-SKIN

Reproductive toxicity has many specific differences from toxicity related to other systems. Since reproduction requires interaction between two people, whereas other forms of environmental toxicity typically affect the development of disease in an exposed person, the expression reproductive toxicity always alludes to a reproductive unit or couple. This aspect is characteristic, however obvious it may be.

For example, it is possible that exposure to a toxic substance by one member of a reproductive couple (e.g., the male) may manifest as an adverse reproductive outcome in the other member of the couple (e.g., increased frequency of miscarriages). Any attempt to analyze the environmental causes of reproductive toxicity must take into account the couple-specific data. There are other characteristic aspects of reproductive toxicology.

Unlike renal, cardiac or pulmonary function, reproductive function develops intermittently. Consequently, occupational exposures may interfere with reproduction, even if they go unnoticed during periods when fertility is not desired. This intermittent characteristic may make it difficult to identify a reproductive toxicant for humans. Another unique feature of reproduction, stemming directly from that prior consideration, is that full assessment of the functional integrity of the reproductive system requires that the couple attempt to achieve pregnancy.

The overall functioning of the reproductive system is controlled by the nervous system and by hormones produced by the glands (endocrine system). The male reproductive neuroendocrine axis consists primarily of the central nervous system (CNS), anterior pituitary and testes. The hypothalamus integrates signals from the CNS and the periphery, and directly regulates the secretion of gonadotropins by the anterior pituitary. In turn, gonadotropins act mainly on the interstitial Leydig cells and the Sertoli and germ cells found in the seminiferous tubules to regulate spermatogenesis and testicular hormone production.

I invite everyone to read Matias’ post with the topic of the day.

Finally, I encourage everyone to reflect on the concept of the day. No one else but us can re-signify our own being
