Estimating male fertility in eastern and western Germany since 1991: A new lowest low?

Male Fertility Around the World and Over Time: How Different is it from Female Fertility?

“…Despite the relative lack of research, empirical evidence on patterns and levels of male fertility has been produced in a variety of contexts (Brouard ; Donadjé ; Dudel and Klüsener ; Estee ; Keilman et al. ; Kuczynski ; Lognard ; Nordfalk et al.…”

Measuring male fertility rates in developing countries with Demographic and Health Surveys: An assessment of three methods

“…The focus on female fertility is explained by a variety of factors, including the implicit assumption that spouses share identical reproductive interests and behaviors (Greene and Biddlecom 2000), lack of data, quality problems with male fertility data, and the fact that the reproductive age range is less clearly defined for males than for females (Andro and Desgrées du Loû 2009;Estee 2004;Field et al 2016;Greene and Biddlecom 2000;Paget and Timaeus 1994;Ratcliffe, Hill, and Walraven 2000;Zhang 2011). Male fertility data is available in many Western countries through civil registration and vital statistics systems (CRVS), and these have been used in a number of studies on male fertility in developed countries (Brouard 1977;Dudel and Klüsener 2016;Lognard 2010;Tragaki and Bagavos 2014;United Nations 2013;Zhang 2011). However, CRVS systems are deficient in many developing countries, and the collection of fertility data in surveys -especially using full birth histories -has to a large extent focused on females.…”

New opportunities for comparative male fertility research: insights from a new data resource based on high-quality birth registers

“…Substantial differences between males and females have also been recorded in the mean age at childbirth. It has, for instance, been shown that in Germany males are on average 3-4 years older than females at childbirth (Dudel and Klüsener 2016). Moreover, according to estimates by Schoumaker (2017), fathers in Mali and Niger are on average up to 12 years older than mothers.…”

“…Why male and female fertility can differ substantially with respect to quantum and timing is not yet well understood. Several mechanisms have been proposed to explain differences in fertility levels, including the ratio of males to females of reproductive age (Dudel and Klüsener 2016;Keilman et al 2014), and gender differences in the timing of births (Schoumaker 2019(Schoumaker , 2017. But the impact of each of these and other potential mechanisms on the quantum of male and female fertility has not been thoroughly studied, and the extent of their respective contributions to fertility differentials remains unknown.…”

“…For instance, survey data on the fertility of males is generally considered to be less reliable, as males are prone to underreport their number of children (e.g., Rendall et al 1999, Vere 2008. However, in recent years, several studies assessing male fertility based on birth register data have been published (Jalovaara et al 2018, Bagavos and Tragaki 2017, Dudel and Klüsener 2016, UN Department of Economic and Social Affairs 2015, Nordfalk et al 2015, Nisén et al 2014, Carmichael 2013, Lappegård et al 2011, Zhang 2011) that focused on single countries or on comparisons of countries. The comparative studies were, however, often limited to a cross-sectional perspective.…”
