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 ...
It is the most widely used fertility drug. [6] Other medications in this class include tamoxifen and raloxifene, although both are not as effective as clomiphene and are thus less widely used for fertility purposes.

[22] [23] "Typical use" means that an individual uses their contraceptive pill at inconsistent times day to day and/or misses scheduled doses. [21] The study reporting the "typical use" failure rate failed to differentiate COCPs and POPs as distinct medications and instead studied them as a combined group, decreasing the validity of this finding.
Nearly 50 years of research links two common insecticides used in food, yards and households to dramatically lower sperm count in men worldwide, a new study found.
The research is mixed on whether cycling affects male fertility, including sperm—but doctors offer some tips on protecting your swimmers, if you have concerns.
