[1] [2] In primates, reproductive synchrony usually takes the form of conception and birth seasonality. [3] The regulatory "clock", in this case, is the sun's position in relation to the tilt of the earth. In nocturnal or partly nocturnal primates—for example, owl monkeys—the periodicity of the moon may also come into play.
Chance of fertilization by menstrual cycle day relative to ovulation [15] Pregnancy rates for sexual intercourse are highest during the menstrual cycle time from some 5 days before until 1 to 2 days after ovulation. [16] For optimal pregnancy chance, there are recommendations of sexual intercourse every 1 or 2 days, [17] or every 2 or 3 days. [18]

The small plant in front is about 1 cm (0.4 in) tall. The concept of "individual" is obviously stretched by this asexual reproductive process. Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents
At birth, female babies have around 1 to 2 million oocytes, and roughly 1,000 immature eggs are lost each month after the first period. In their late 30s, most women have about 25,000 oocytes ...
In a study from 1993, the mean value was given as 9.2 cm, in a study from 2006 only 6.27 cm with a variation of the lengths between 4.1 and 9.5 cm. [71] [72] If the woman is not sufficiently aroused with a deep penetration the penis bumps against the cervix causing pain. If the stretching capacity of the vagina is exceeded by a too large penis ...
Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. [6] [7] Sexual reproduction also occurs in some unicellular eukaryotes. [2] [8] Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such as bacteria and archaea.
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [1] By analogy, the term is used in human reproduction , but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious recessive traits resulting from ...
