ABSTRACT

Objective: To describe changes in a semen analysis before getting a spontaneous pregnancy.
Material and methods: In an observational, descriptive, longitudinal and retrospective study a semen analysis of the first evaluation of 96 patients was compared with the exam accomplished before getting a spontaneous pregnancy. A descriptive analysis of the semen exam was performed and the results of both exams were compared by means of a t Student test with statistical significance for p‹‹0.05.
Results: In the first analysis, the volume, density, mobility, normal morphology, total number of mobile cells and total number of mobile cells with normal morphology (TNMCNM) were 2.45 ± 1.39mL, 79 ± 43 million/mL, 40 ± 21%, 27 ± 14%, 84 ± 84 million and 23 ± 29 million, respectively, and in the final analysis were 2.6 ±1.26 mL, 79 ± 42 million/mL, 43 ± 21%, 28 ± 14%, 97±98 million and 28±33 million, respectively. None of them were different. In four patients with low testosterone and a LH/FS ≥1 ratio, volume increased from 1 ± 0.31 to 1.65 ± 0.17 mL and normal morphology from 22 ± 7 to 31 ± 5. Both variables were different. In six patients with high prolactine and low testosterone or low FSH, density increased from 56 ± 21 to 114 ± 18 million/mL and TNMCNM from 14 ± 12 to 46 ± 32 million. Both variables were different.
Conclusion: Only those patients with low testosterone and a LH/FSH≥1 rate had an increase of semen volume and normal morphology. Those with high prolactine-low testosterone or high prolactine-low FSH had an increase of the total mobile cells and the total mobile cells with normal morphology. There were not changes in any semen variable of the other patients.
