  abstract: Eight pony stallions were paired by estimated daily sperm
  abstract: output (DSO) and randomly assigned to one of two treatments.
  abstract: Stallions received 44 []g/kg BW estradiol cypionate (ECP) or
  abstract: an equivalent volume of physiological saline solution on
  abstract: alternate days during the breeding season. Blood samples
  abstract: collected immediately preceding each injection were assayed
  abstract: for luteinizing hormone (LH), estradiol-17[] (E2) and
  abstract: testosterone (T). Semen collected at 3.5-d intervals was
  abstract: evaluated for spermatozoal motility, total number of sperm
  abstract: per ejaculate and seminal plasma E2 (SE2). Prior to and
  abstract: after four, eight and 12 wk on treatment, DSO was determined.
  abstract: Data were separated into nine 10-d periods for statistical
  abstract: analysis. As expected, E2 was higher (p<.05) in the ECP-
  abstract: treated group after 20 d (period 2) of treatment and for the
  abstract: remainder of the experiment. Although, E2 was higher (p<.05)
  abstract: in the C group prior to treatment, there was no difference
  abstract: between groups after 10 d of treatment. ECP stallions had
  abstract: higher (p<.05) DSO after 30 d on treatment. After 40 and 50
  abstract: d (periods 4 and 5), ECP stallions demonstrated higher
  abstract: (p<.05) total sperm per period. This was preceded by higher
  abstract: (p<.05) LH concentrations for ECP stallions after periods 1
  abstract: and 2. There were no differences (p>.05) in SE2 between
  abstract: groups after periods 1 and 2. Between 30 and 70 d, ECP
  abstract: stallions had higher SE2 concentrations. Elevated SE2 in ECP
  abstract: stallions was moderately correlated to total sperm per period
  abstract: (r =.53). No differences (p>.05) were seen between 30 and 60
  abstract: d for LH, after 60 d for DSO or after 60, 70 or 80 d for
  abstract: total sperm per period. ECP stallions had higher (p<.05) DSO
  abstract: and total sperm per period after 90 d. Additionally, LH
  abstract: remained higher (p<.05) in the ECP group after 60 d. Seminal
  abstract: plasma E2 was higher (p<.05) in ECP stallions after 90 d.
  abstract: There were no differences between the two groups for
  abstract: testicular cell data. Elevated LH concentrations in ECP
  abstract: stallions demonstrated that estrogen treatment did not
  abstract: inhibit LH in this study. Treatment with ECP did not have a
  abstract: detrimental effect on potential DSP in this study.
