TLDR
The data suggest that variations in male reproductive function may affect population based birth rates and, therefore, may be more important than previously understood.About:

Tony M. Plant,Gary R. Marshall +1 more
TL;DR: An integrative analysis of the role of FSH in the control of testicular function in higher primates, including man is provided, with the presentation of a model for the operation of the FSH-inhibin B feedback control system regulating sperm production postpubertally in monkey and man.

Semen quality and male reproductive health: the controversy about human sperm concentration decline
TL;DR: In this paper, a meta-analysis of 61 articles published by Carlsen et al. concluded that the mean sperm count of healthy men had declined by 1% per year over the previous 50 years.
Journal ArticleDOI
Therapeutic potential of selective estrogen receptor modulators.

Evidence for decreasing quality of semen during past 50 years.
TL;DR: There has been a genuine decline in semen quality over the past 50 years, and as male fertility is to some extent correlated with sperm count the results may reflect an overall reduction in male fertility.
Laboratory manual for the examination of human semen and semen-cervical mucus interaction.
TL;DR: This laboratory manual consists of 2 sections which describe methods of examination of human semen and semen-cervical mucus interaction in order to standardize procedures and facilitate evaluation and comparison of research reports.

Decline in Semen Quality among Fertile Men in Paris during the Past 20 Years
TL;DR: The volume of seminal fluid, the sperm concentration, and the percentages of motile and morphologically normal spermatozoa in 1351 healthy fertile men from 1973 through 1992 were measured.
Journal ArticleDOI
Evidence of deteriorating semen quality in the United Kingdom: birth cohort study in 577 men in Scotland over 11 years
TL;DR: Data confirm previously published data from other countries that semen quality is changing, declining by about 2.1% per year Research is urgently required to examine the function as well as the number of sperm and to assess whether these changes are affecting human health and male fertility.

Semen analyses in 1,283 men from the United States over a 25-year period: no decline in quality
TL;DR: The data show no decline in sperm counts over a 25-year period in 1,283 men who banked sperm before vasectomy at three distinct geographical sites in the United States.
