Does mercury poisoning cause infertility?

How are metals linked to infertility?
Heavy metals alter several reproductive functions in both males and females like a decrease in sperm count, motility, viability, spermatogenesis, hormonal imbalance, follicular atresia, and delay in oocyte maturation, and so forth, and thus, forms an important aspect of reproductive toxicology.
Does mercury affect male fertility?
Mercury treatment produced a reduction in sperm quantity (testis and epididymis) and daily sperm production, following by decrease in sperm motility and increase on head and tail morphologic abnormalities.
What can mercury do to a fetus?

Can heavy metals cause male infertility?
Metals can cause male infertility through affection of spermatogenesis and sperm quality. Strong evidences confirm that male infertility in metal-exposed humans is mediated via various mechanisms such as production of reactive oxygen species (ROS).
Can heavy metals affect fertility?
Heavy Metals and Fertility Heavy metals have been identified as factors affecting human fertility. Significant correlations were found between different heavy metals and clinical parameters (age, body mass index, ethnicity) as well as gynecological conditions (uterine fibroids, miscarriages, hormonal disorders).
How does human fertilization work?
Human fertilization is the fusion of an egg and sperm resulting in a zygote. It is a complex process that occurs in many steps. The egg and sperm are known as gametes or the sex cells of the body. Successful human fertilization relies on a few key events. First, ovulation, or the release of one egg from the ovary, needs to occur.

Could humans ever live on Mercury?
Mercury is the second hottest planet, and it’s very very close to the Sun. This is far too hot for humans to ever live on Mercury in their current form.
Can two egg cells be used to fertilize a human being?
No. For human fertilization to give rise to the development of a new human being, there must be an egg and a sperm. To date, fertilization using two egg cells is impossible. Not even Reproductive Medicine has been able to make this possible.
