santolla have shown the development of sex cells in males and females (Vinuesa, 1984; Vinuesa & Labal de Vinuesa, 1998; Lovrich & Vinuesa, 2016), and established that oogenesis in females is a cycle that lasts 20 to 23 months; two parallel gametogenic cycles in the ovaries occur.
Since the origin of an ovotestis in Loxechinus albus could consider have any number of possibilities, such as a simultaneous hermaphrodite with unsynchronized gametogenic cycles or the ova had been spawned out leaving residual sperm.
where n is the number of oysters present in a given gametogenic stage, s is the numerical ranking of the given gametogenic stage, and N is the total number of individuals in the sample (Seed 1969, Braley 1982, Braley 1984).
The close correlation between the annual neurosecretory cycle of the "type al cells" and the gametogenic cycle has suggests a possible role of these cells in the control of the reproduction in mytilids; secretory material is accumulated in the cerebral ganglia (contain 75% of the neurosecretory cells) during gametogenesis and then evacuated from the cells when the gametes become fully mature (Mathieu et al.).
Reproductive cycle: Histological analysis showed that the variations in gonad weight, color and tubule diameter reflected different gametogenic stages (level of maturity).
In other hand, the peak observed in January (period of sexual rest), and the increase in spring did not match with the gametogenic cycle.
The particularity of this case resides in the fact that the left ovary whose ovulatory and gametogenic function has been inhibited by presence of the tumor mass, regained its activity in the first month after the laparoscopic removal of the cyst.

It combines the gametogenic and steroidogenic functions in a unique manner (Longman).
were determined by assigning the numeric ranks 0-4 for each gametogenic stage (0=spent 1=early developing 2=nearly ripe 3=ripe 4=spawning).
capitata has been observed to spawn during the summer months (Heyward, 1986; Hunter, 1988; Kolinski and Cox, 2003; Padilla-Gamino and Gates, 2012); however, there is no information on the length of the gametogenic cycle or on seasonal spawning in single individuals.
Sampled Platygyra acuta colonies covered three spawning events in 1998, 1999, and 2011; all had a single annual gametogenic cycle and similar annual patterns of gametogenesis with oogenesis occurring for 6-7 months from November 1998 to May 1999 and from November 2010 to June 2011 (Figures 2 and 3).
