The most common form of sterilization in dogs and cats is surgical, spaying in females and castration in males. Non-surgical fertility control can either result in sterilization or temporary contraception and could offer a cheaper way to keep wild dog and cat populations under control. As of 2019, only contraceptives are commercially available.
Terms oligospermia, oligozoospermia, and low sperm count refer to semen with a low concentration of sperm [1] and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically oligoasthenoteratozoospermia). There has been interest ...
Necrospermia is usually confused with asthenozoospermia, which is the inability of the sperm to move even when alive. To check for necrospermia, samples with a high percentage of immobile sperm are stained to check for vitality. If they are dead sperm they will be stained, as the membrane is broken and the dye enters indiscriminately.
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml).
Another way to look at costs is to determine the expected cost of establishing a pregnancy. Thus, if a clomiphene treatment has a chance to establish a pregnancy in 8% of cycles and costs $780, the expected cost is $9,400 to establish a pregnancy, compared to an IVF cycle (cycle fecundity 40%) with a corresponding expected cost of $46,800 ...
In domestic dogs, sexual maturity occurs between the ages of 6 and 12 months for both males and females, although this can be delayed until up to two years of age for some large breeds. [2] Pregnancy is possible as soon as the first estrus cycle, but breeding is not recommended prior to the second cycle. [3]
The average age of death of intact dogs was 7.9 years versus a significantly older 9.4 years for altered dogs. Plus a male dog that is fixed won't try and mount every person who comes over to ...
Sperm count and its relationship to pregnancy rate Numerous studies show the association between obesity in men and infertility. In the developed world, the temporal trend for the reduction in sperm parameters (sperm count, motility, morphology, volume, fructose level, and pH) reflects the increasing prevalence of obesity.
