Heredity, environment, and lifestyle can all play a part when it comes to infertility. Heredity, environment, and lifestyle can all play a part when it comes to what causes infertility in men and women.
Many genetic and environmental factors as well as crop management decisions during seed production influence the vigor of seeds. Among these factors are variety, weather conditions during seed development and maturation, mechanical damage during harvest or cleaning, inadequate drying, and unsuitable storage conditions.
Choline found in cottonseed oil helps to metabolize lipids located in the liver so that liver damage caused by an accumulation of lipids is prevented (otherwise known as fatty liver disease).

The differences in susceptibility were more pronounced at the moderate damage levels and that the damage in less susceptible cultivars increased or decreased according to the insect pressure. There were significant differences in the gossypol, tannins, moisture, phenols and sugar content among the genotypes tested.
Cottonseed meal had similar damage to seminiferous epithelium when compared to bulls fed 16 gday ' of free gossypol from whole cottonseed. The spermicidal effect of gossypol may also depend on the predominant + or - gossypol enantiomer present in the cottonseed product due to its stereospecific.
The situation becomes complicated due to climate change and variability as temperature and unpredicted rainfalls during production are badly affecting cottonseed quality. Physical quality losses by seed cracking during ginning and physiological quality losses arising from respiration are inevitable and irreducible.
However, cotton can withstand as much as 75% defoliation before the third true leaf stage without impacting yield, although maturity may be delayed. Factors that inhibit early leaf development include: cold temperatures, wind or hail damage, and foliage feeding insects. Root damaging organisms can also stunt early leaf development.

Other factors, such as planting too deep, poor seed bed conditions, compacted soil, nematode or insect infestations, and misapplication of soil-applied herbicides, may increase the problem. Additionally, seedling diseases tend to be more severe in reduced tillage situations and when beds are absent.
The location of seed structures plays an important role in determining the seeds’ susceptibility to mechanical injuries and weather damage. Impacts to the embryonic axis can cause severe damage, resulting in abnormal seedlings or death of the seed.
Sawan et al (1999) found that both seed size and seed density are correlated with seedling vigour in cotton. Small seeds may lack food reserves, and large seeds may be more easily damaged by harvesting or have metabolic abnormality. These can be removed from an otherwise healthy seedlot by seiving.
Four in 10 cases are linked to the male partner, estimates the american society for reproductive medicine.
Numerous factors affect the general functional quality of the egg shell. These factors affect the quality of the shell mostly prior to when the egg is laid. The thickness of an egg shell is determined by the amount of time it spends in the shell gland (uterus) and the rate of calcium deposition during egg shell formation.
Overton - feeding whole cottonseed to both free-ranging and ranched deer is a common practice this time of year. But a recent study done by the texas agricultural experiment station finds a toxic element in whole cottonseed adversely retards antler growth, lessens body condition scores and lowers.

“environmental factors account for 79 percent of the color variability in cotton,” says dever. “when total rainfall after the cotton opens exceeds 2 inches, loss in color grade will occur. Discoloration can also be caused by the action of microorganisms in connection with boll rot or insect damage.
Food and feed products may contain a number of antinutritional factors that may adversely affect protein digestibility and amino acid availability. Antinutritional factors may occur naturally, such as glucosinolates in mustard and rapeseed protein products, trypsin inhibitors and hemagglutinins in legumes, tannins in legumes and cereals, phytates in cereals and oilseeds, and gossypol in cottonseed protein products.
