Correction to: Comparative testis structure and function in three representative mice strains

Erratum to: Cell and Tissue Research https://doi.org/10.1007/s00441-020–03239-0

The authors regret that in our published paper entitled “Comparative testis structure and function in three representative mice strains.” Cell and Tissue Research, 2020 Jul 14; the Tables 1, 3 and 4 as well as Fig. 2 are presenting some inaccurate information.

Table 1 Biometric and morphometric data in three different mice strains (mean ± SEM)

Table 3 Cell counts and ratios per seminiferous tubule cross sections at stage VII of the seminiferous epithelium cycle, in three different mice strains (mean ± SEM)

Table 4 Comparative data related to biometry, testis stereology and spermatogenesis in mice strains already investigated

Specifically, the data referring to seminiferous tubules diameter and cell counts need to be corrected. However, as detailed in the "Material and Methods" section, these data are used for calculating quantitative testicular parameters, such as the total length of seminiferous tubule per testis and per testis gram; cell ratios; Sertoli cell efficiency and numbers; and daily sperm production per testis and per gram of testis. Although imperative, the replacement of the absolute values of each of these cited parameters, in overall, did not change the comparative observations and the biological context of our results. Therefore, the error does not affect the interpretation of the results or the scientific conclusions of the article in any way.

The authors would like to apologize for any inconvenience made by this mistake.

Therefore, in our article we make the following corrigendum in the text:

• 1. Replacement of Tables 1, 3 and 4 showing the correct values for tubular diameter, total length of seminiferous tubule per testis and per testis gram and cell counts and ratios.

• 2. Replacement of Fig. 2 with the correct values for Sertoli cell efficiency and numbers and daily sperm production per testis and per gram of testis. Consequently, the subtitle must be corrected as follows (for the changes, see underlined text):

Fig. 2

Sertoli cell and sperm production parameters in the three mice strains investigated (a–e). As it can be noted, the only statistical difference observed was on daily sperm production per testis (e), which was significantly increased in Swiss mice (*) in comparison to the C57BL/6. T test was performed to compare differences between C57BL/6 and Swiss strains (p < 0.05) due to Gaussian distribution in these groups”

As a consequence of the tables and figure alterations, the text has the following changes (for the changes, see underlined text).
