Reproductive toxicants may adversely affect sexual function, ovarian failure, fertility as well as causing developmental toxicity in the offspring. [2] [3] Lowered effective fertility related to reproductive toxicity relates to both male and female effects alike and is reflected in decreased sperm counts, semen quality and ovarian failure.
Pomegranates were cultivated by Bronze Age cultures, and wild water chestnuts were consumed in large quantities by prehistoric Europeans. [9] Eucalyptus trees are the tallest known flowering plants, up to 100 m (330 ft) or more; they are grown for timber and for their oils, used in candy, perfumes and cough medicine. [10]

In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), [1] of an infection is the ...
The tertiary sex ratio is equivalent to the adult sex ratio (ASR), which is defined as the ratio of adult males to females in a population. [ 6 ] [ 7 ] The operational sex ratio (OSR) is the ratio of sexually active males to females in a population, and is therefore derived from a subset of the individuals included when calculating the ASR.

If the hazard prevents sperm from being made, sterility is permanent. Sperm shape. Reproductive hazards may cause the shape of sperm cells to be different.
